Member Function Documentation

static DDS_ReturnCode_t DDSStringTypeSupport::register_type ( DDSDomainParticipant participant,
const char *  type_name = "DDS::String" 
)
static

Allows an application to communicate to RTI Connext the existence of the ::char* data type.

By default, The ::char* built-in type is automatically registered when a DomainParticipant is created using the type_name returned by DDSStringTypeSupport::get_type_name. Therefore, the usage of this function is optional and it is only required when the automatic built-in type registration is disabled using the participant property "dds.builtin_type.auto_register".

This method can also be used to register the same DDSStringTypeSupport with a DDSDomainParticipant using different values for the type_name.

If register_type is called multiple times with the same DDSDomainParticipant and type_name, the second (and subsequent) registrations are ignored by the operation.

Parameters
participant<<in>> the DDSDomainParticipant to register the data type ::char* with. Cannot be NULL.
type_name<<in>> the type name under with the data type ::char* is registered with the participant; this type name is used when creating a new DDSTopic. (See DDSDomainParticipant::create_topic.) The name may not be NULL or longer than 255 characters.
Returns
One of the Standard Return Codes, DDS_RETCODE_PRECONDITION_NOT_MET or DDS_RETCODE_OUT_OF_RESOURCES.
MT Safety:
UNSAFE on the FIRST call. It is not safe for two threads to simultaneously make the first call to register a type. Subsequent calls are thread safe.

DDSDomainParticipant::create_topic
static DDS_ReturnCode_t DDSStringTypeSupport::unregister_type ( DDSDomainParticipant participant,
const char *  type_name = "DDS::String" 
)
static

Allows an application to unregister the ::char* data type from RTI Connext. After calling unregister_type, no further communication using this type is possible.

Precondition
The ::char* type with type_name is registered with the participant and all DDSTopic objects referencing the type have been destroyed. If the type is not registered with the participant, or if any DDSTopic is associated with the type, the operation will fail with DDS_RETCODE_ERROR.
Postcondition
All information about the type is removed from RTI Connext. No further communication using this type is possible.
Parameters
participant<<in>> the DDSDomainParticipant to unregister the data type ::char* from. Cannot be NULL.
type_name<<in>> the type name under with the data type ::char* is registered with the participant. The name should match a name that has been previously used to register a type with the participant. Cannot be NULL.
Returns
One of the Standard Return Codes, DDS_RETCODE_BAD_PARAMETER or DDS_RETCODE_ERROR
MT Safety:
SAFE.
See Also
DDSStringTypeSupport::register_type
static const char* DDSStringTypeSupport::get_type_name ( )
static

Get the default name for the ::char* type.

Can be used for calling DDSStringTypeSupport::register_type or creating DDSTopic.

Returns
default name for the ::char* type.

static void DDSStringTypeSupport::print_data ( const char *  a_data)
static

<<eXtension>> Print value of data type to standard out.

The generated implementation of the operation knows how to print value of a data type.

Parameters
a_data<<in>> String to be printed.
