A sample of any complex data type, which can be inspected and manipulated reflectively.
Objects of type DDS_DynamicData represent corresponding objects of the type identified by their DDS_TypeCode. Because the definition of these types may not have existed at compile time on the system on which the application is running, you will interact with the data using an API of reflective getters and setters.
For example, if you had access to your data types at compile time, you could do this:
Instead, you will do something like this:
DDS_DynamicData objects can represent any complex data type, including those of type kinds DDS_TK_ARRAY, DDS_TK_SEQUENCE, DDS_TK_STRUCT, DDS_TK_UNION, DDS_TK_VALUE, and DDS_TK_SPARSE. They cannot represent objects of basic types (e.g. integers and strings). Since those type definitions always exist on every system, you can examine their objects directly.
The members of a data type can be identified in one of two ways: by their name or by their numeric ID. The former is often more transparent to human users; the latter is typically faster.
You define the name and ID of a type member when you add that member to that type. When you define a sparse type, you will typically choose both explicitly. If you define your type in IDL or XML, the name will be the field name that appears in the type definition; the ID will be the one-based index of the field in declaration order. For example, in the following IDL structure, the ID of theLong
is 2.
For unions (DDS_TK_UNION), the ID of a member is the discriminator value corresponding to that member.
The "members" of array and sequence types, unlike those of structure and union types, don't have names or explicit member IDs. However, they may nevertheless be accessed by "ID": the ID is one more than the index. (The first element has ID 1, the second 2, etc.)
Multi-dimensional arrays are effectively flattened by this pattern. For example, for an array theArray
[4][5], accessing ID 7 is equivalent to index 6, or the second element of the second group of 5.
To determine the length of a collection-typed member of a structure or union, you have two choices:
The Dynamic Data API is large when measured by the number of methods it contains. But each method falls into one of a very small number of categories. You will find it easier to navigate this documentation if you understand these categories.
Managing the lifecycle of DDS_DynamicData objects is simple. You have two choices:
DDSDynamicDataTypeSupport | DDS_DynamicData |
---|---|
DDSDynamicDataTypeSupport::create_data | ::DDS_DynamicData::DDS_DynamicData |
DDSDynamicDataTypeSupport::delete_data | ::DDS_DynamicData::~DDS_DynamicData |
You can also copy DDS_DynamicData objects:
You can test them for equality:
And you can print their contents:
Most methods get or set the value of some field. These methods are named according to the type of the field they access.
The names of integer types vary across languages. The programming API for each language reflects that programming language. However, if your chosen language does not use the same names as the language that you used to define your types (e.g., IDL), or if you need to interoperate among programming languages, you will need to understand these differences. They are explained the following table.
Type | IDL | C, C++ | C# | Java |
---|---|---|---|---|
16-bit integer | short | DDS_Short | short | short |
32-bit integer | long | DDS_Long | int | int |
64-bit integer | long long | DDS_LongLong | long | long |
When working with a DDS_DynamicData object representing an array or sequence, calling one of the "get" methods below for an index that is out of bounds will result in DDS_RETCODE_NO_DATA. Calling "set" for an index that is past the end of a sequence will cause that sequence to automatically lengthen (filling with default contents).
Get | Set |
---|---|
DDS_DynamicData::get_complex_member | DDS_DynamicData::set_complex_member |
In addition to getting or setting a field, you can "clear" its value; that is, set it to a default zero value.
Not all components of your application will have static knowledge of all of the fields of your type. Sometimes, you will want to query meta-data about the fields that appear in a given data sample.
Sometimes, you may want to change the association between a data object and its type. This is not something you can do with a typical object, but with DDS_DynamicData objects, it is a powerful capability. It allows you to, for example, examine nested structures without copying them by using a "bound" DDS_DynamicData object as a view into an enclosing DDS_DynamicData object.
Keys can be specified in dynamically defined types just as they can in types defined in generated code. However, there are some minor restrictions when sparse value types are involved (see DDS_TK_SPARSE).
Due to the way in which DDS_DynamicData objects manage their internal state, it is typically more efficient, when setting the field values of a DDS_DynamicData for the first time, to do so in the declared order of those fields.
For example, suppose a type definition like the following:
The richness of the type system makes it difficult to fully characterize the performance differences between all access patterns. Nevertheless, the following are generally true:
my_float
, then my_bytes
, and finally my_short
. DDS_DynamicData::DDS_DynamicData | ( | const DDS_TypeCode * | type, |
const DDS_DynamicDataProperty_t & | property | ||
) |
The constructor for new DDS_DynamicData objects.
The type parameter may be NULL. In that case, this DDS_DynamicData must be bound with DDS_DynamicData::bind_type or DDS_DynamicData::bind_complex_member before it can be used.
If the DDS_TypeCode is not NULL, the newly constructed DDS_DynamicData object will retain a reference to it. It is not safe to delete the DDS_TypeCode until all samples that use it have themselves been deleted.
In most cases, it is not necessary to call this constructor explicitly. Instead, use DDSDynamicDataTypeSupport::create_data, and the DDS_TypeCode and properties will be specified for you. Using the factory method also ensures that the memory management contract documented above is followed correctly, because the DDSDynamicDataTypeSupport object maintains the DDS_TypeCode used by the samples it creates.
However you create a DDS_DynamicData object, you must delete it when you are finished with it. If you choose to use this constructor, delete the object with the destructor: ::DDS_DynamicData::~DDS_DynamicData.
NOTE that RTI Connext does not explicitly generate any exceptions in this constructor, because C++ exception support is not consistent across all platforms on which RTI Connext runs. Therefore, to check whether construction succeeded, you must use the DDS_DynamicData::is_valid method. Alternatively, you can create an DDS_DynamicData object with DDSDynamicDataTypeSupport::create_data, which returns NULL on failure, eliminating the need to call DDS_DynamicData::is_valid.
type | <<in>> The type of which the new object will represent an object. |
property | <<in>> Properties that configure the behavior of the new object. Most users can simply use DDS_DYNAMIC_DATA_PROPERTY_DEFAULT. |
DDS_Boolean DDS_DynamicData::is_valid | ( | ) | const |
Indicates whether the object was constructed properly.
This method returns DDS_BOOLEAN_TRUE if the constructor succeeded; it returns DDS_BOOLEAN_FALSE if the constructor failed for any reason, which should also have resulted in a log message. It is only necessary to call this method if you created the DDS_DynamicData object using the constructor, ::DDS_DynamicData::DDS_DynamicData.
Possible failure reasons include passing an invalid type or invalid properties to the constructor.
This method is necessary because C++ exception support is not consistent across all of the platforms on which RTI Connext runs. Therefore, the implementation does not throw any exceptions in the constructor.

Deeply copy from the given object to this object.

Indicate whether the contents of another DDS_DynamicData sample are the same as those of this one.
This operation compares the data and type of existing members. The types of non-instantiated members may differ in sparse types.
DDS_DynamicData& DDS_DynamicData::operator= | ( | const DDS_DynamicData & | src | ) |
DDS_Boolean DDS_DynamicData::operator== | ( | const DDS_DynamicData & | other | ) | const |
Indicate whether the contents of another DDS_DynamicData sample are the same as those of this one.
This operation compares the data and type of existing members. The types of non-instantiated members may differ in sparse types.
DDS_ReturnCode_t DDS_DynamicData::clear_all_members | ( | ) |
Clear the contents of all data members of this object, including key members.
DDS_ReturnCode_t DDS_DynamicData::clear_nonkey_members | ( | ) |
Clear the contents of all data members of this object, not including key members.
This method is only applicable to sparse value types.
DDS_ReturnCode_t DDS_DynamicData::clear_member | ( | const char * | member_name, |
DDS_DynamicDataMemberId | member_id | ||
) |
Clear the contents of a single data member of this object.
This method is only applicable to sparse value types.
member_name | <<in>> The name of the member or NULL to look up the member by its ID. |
member_id | <<in>> The ID of the member or DDS_DYNAMIC_DATA_MEMBER_ID_UNSPECIFIED to look up by name. See Member Names and IDs. |
DDS_ReturnCode_t DDS_DynamicData::set_buffer | ( | DDS_Octet * | storage, |
DDS_Long | size | ||
) |
Associate a buffer with this dynamic data object.
The DynamicData object will use the input buffer to store its value.
If the DynamicData object already has a value, this function will clear the contents of all data members.
The memory of the buffer being replaced will be freed, unless the buffer was assigned by a previous call to this method.
If the size of the input buffer is not big enough to hold the future value of the DynamicData object, the set operations will return DDS_RETCODE_OUT_OF_RESOURCES when the size is exceeded.
The internal representation of a DynamicData object is based on CDR encapsulation and introduces additional overhead beyond the data representation of the equivalent C structure. When providing an input buffer, try to account for that overhead.
The method DDS_DynamicData::get_estimated_max_buffer_size can be used to obtain an estimated maximum size for the input buffer. This size is calculated based on an assignment pattern where the value of a data member is set a single time between calls to DDS_DynamicData::clear_all_members.
DDS_ReturnCode_t DDS_DynamicData::get_estimated_max_buffer_size | ( | DDS_Long & | size | ) |
Get the estimated maximum buffer size for a DynamicData object.
This method gets the estimated maximum buffer size of a DynamicData object based on the associated type.
The output size is calculated based on an assignment pattern where the value of a data member is set a single time between calls to DDS_DynamicData::clear_all_members.
If this is not the case (for example, the value of a string member is set multiple times), the maximum size returned by this method may not be representative.
This method can be used to obtain the size of the buffer provided to the method DDS_DynamicData::set_buffer.
size | <<out>> Estimated maximum buffer size in bytes. |
DDS_ReturnCode_t DDS_DynamicData::print | ( | FILE * | fp, |
int | indent | ||
) | const |
Output a textual representation of this object and its contents to the given file.
This method is equivalent to DDSDynamicDataTypeSupport::print_data.
Warning: This operation may not display any data for members at the end of a data structure that have not been explicitly set before the data sample is serialized. This will not be a problem on a received data sample, which should always correctly display all members.
fp | <<in>> The file to which the object should be printed. |
indent | <<in>> The output of this method will be pretty-printed. This argument indicates the amount of initial indentation of the output. |
void DDS_DynamicData::get_info | ( | DDS_DynamicDataInfo & | info_out | ) | const |
Fill in the given descriptor with information about this DDS_DynamicData.
info_out | <<out>> The descriptor object whose contents will be overwritten by this operation. |
DDS_ReturnCode_t DDS_DynamicData::bind_type | ( | const DDS_TypeCode * | type | ) |
If this DDS_DynamicData object is not yet associated with a data type, set that type now to the given DDS_TypeCode.
This advanced operation allows you to reuse a single DDS_DynamicData object with multiple data types.
Note that the DDS_DynamicData object will retain a reference to the DDS_TypeCode object you provide. It is not safe to delete the DDS_TypeCode until after it is unbound.
type | <<in>> The type to associate with this DDS_DynamicData object. |
DDS_ReturnCode_t DDS_DynamicData::unbind_type | ( | ) |
Dissociate this DDS_DynamicData object from any particular data type.
This step is necessary before the object can be associated with a new data type.
This operation clears all members as a side effect.
DDS_ReturnCode_t DDS_DynamicData::bind_complex_member | ( | DDS_DynamicData & | value_out, |
const char * | member_name, | ||
DDS_DynamicDataMemberId | member_id | ||
) |
Use another DDS_DynamicData object to provide access to a complex field of this DDS_DynamicData object.
For example, consider the following data types:
Suppose you have an instance of MyOuterType
, and you would like to examine the contents of its member complexMember
. To do this, you must bind another DDS_DynamicData object to that member. This operation will bind the type code of the member to the provided DDS_DynamicData object and perform additional initialization.
The following example demonstrates the usage pattern. Note that error handling has been omitted for brevity.
This operation is only permitted when the object toBeBound
(named as in the example above) is not currently associated with any type, including already being bound to another member. You can see in the example that this object is created directly with the constructer and is not provided with a DDS_TypeCode.
Only a single member of a given DDS_DynamicData object may be bound at one time – however, members of members may be recursively bound to any depth. Furthermore, while the outer object has a bound member, it may only be modified through that bound member. That is, after calling this member, all "set" operations on the outer object will be disabled until DDS_DynamicData::unbind_complex_member has been called. Furthermore, any bound member must be unbound before a sample can be written or deleted.
This method is logically related to DDS_DynamicData::get_complex_member in that both allow you to examine the state of nested objects. They are different in an important way: this method provides a view into an outer object, such that any change made to the inner object will be reflected in the outer. But the DDS_DynamicData::get_complex_member operation copies the state of the nested object; changes to it will not be reflected in the source object.
Note that you can bind to a member of a sequence at an index that is past the current length of that sequence. In that case, this method behaves like a "set" method: it automatically lengthens the sequence (filling in default elements) to allow the bind to take place. See Getters and Setters.
value_out | <<out>> The object that you wish to bind to the field. |
member_name | <<in>> The name of the member or NULL to look up the member by its ID. |
member_id | <<in>> The ID of the member or DDS_DYNAMIC_DATA_MEMBER_ID_UNSPECIFIED to look up by name. See Member Names and IDs. |
DDS_ReturnCode_t DDS_DynamicData::unbind_complex_member | ( | DDS_DynamicData & | value | ) |
Tear down the association created by a DDS_DynamicData::bind_complex_member operation, committing any changes to the outer object since then.
Some changes to the outer object will not be observable until after you have performed this operation.
If you have called DDS_DynamicData::bind_complex_member on a data sample, you must unbind before writing or deleting the sample.
value | <<in>> The same object you passed to DDS_DynamicData::bind_complex_member. This argument is used for error checking purposes. |
const DDS_TypeCode* DDS_DynamicData::get_type | ( | ) | const |
Get the data type, of which this DDS_DynamicData represents an instance.
DDS_TCKind DDS_DynamicData::get_type_kind | ( | ) | const |
Get the kind of this object's data type.
This is a convenience method. It's equivalent to calling DDS_DynamicData::get_type followed by DDS_TypeCode::kind.
DDS_UnsignedLong DDS_DynamicData::get_member_count | ( | ) | const |
Get the number of members in this sample.
For objects of type kind DDS_TK_ARRAY or DDS_TK_SEQUENCE, this method returns the number of elements in the collection.
For objects of type kind DDS_TK_STRUCT or DDS_TK_VALUE, it returns the number of fields in the sample, which will always be the same as the number of fields in the type.
For objects of type kind DDS_TK_SPARSE, it returns the number of fields in the sample, which may be less than or equal to the number of fields in the type.

) | const |
Indicates whether a member of a particular name/ID exists in this data sample.
