Detailed Description

The definition of a particular data type, which you can use to inspect the name, members, and other properties of types generated with rtiddsgen or to modify types you define yourself at runtime.

You create com.rti.dds.typecode.TypeCode objects using the com.rti.dds.typecode.TypeCodeFactory singleton. Then you can use the methods on this class to inspect and modify the data type definition.

This class is based on a similar class from CORBA.

MT Safety:
SAFE for read-only access, UNSAFE for modification. Modifying a single com.rti.dds.typecode.TypeCode object concurrently from multiple threads is unsafe. Modifying a com.rti.dds.typecode.TypeCode from a single thread while concurrently reading the state of that com.rti.dds.typecode.TypeCode from another thread is also unsafe. However, reading the state of a com.rti.dds.typecode.TypeCode concurrently from multiple threads, without any modification, is safe.

Member Function Documentation

TCKind kind ( )

Gets the com.rti.dds.typecode.TCKind value of a type code.

Retrieves the kind of this com.rti.dds.typecode.TypeCode object. The kind of a type code determines which com.rti.dds.typecode.TypeCode methods may legally be invoked on it.

MT Safety:
SAFE.
Returns
The type code kind.
ExtensibilityKind extensibility_kind ( )

Gets the com.rti.dds.typecode.ExtensibilityKind value of a type code.

Retrieves the extensibility kind of this com.rti.dds.typecode.TypeCode object.

In some cases, it is desirable for types to evolve without breaking interoperability with deployed components already using those types. For example:

  • A new set of applications to be integrated into an existing system may want to introduce additional fields into a structure. These new fields can be safely ignored by already deployed applications, but applications that do understand the new fields can benefit from their presence.

  • A new set of applications to be integrated into an existing system may want to increase the maximum size of some sequence or string in a Type. Existing applications can receive data samples from these new applications as long as the actual number of elements (or length of the strings) in the received data sample does not exceed what the receiving applications expects. If a received data sample exceeds the limits expected by the receiving application, then the sample can be safely ignored (filtered out) by the receiver.

In order to support use cases such as these, the type system introduces the concept of extensible and mutable types.

  • A type may be final, indicating that the range of its possible data values is strictly defined. In particular, it is not possible to add elements to members of collection or aggregated types while maintaining type assignability.

  • A type may be extensible, indicating that two types, where one contains all of the elements/members of the other plus additional elements/members appended to the end, may remain assignable.

  • A type may be mutable, indicating that two types may differ from one another in the additional, removal, and/or transposition of elements/members while remaining assignable.

The extensibility of com.rti.dds.typecode.TCKind.TK_STRUCT, com.rti.dds.typecode.TCKind.TK_UNION, com.rti.dds.typecode.TCKind.TK_VALUE, and com.rti.dds.typecode.TCKind.TK_ENUM can be change using the built-in "Extensibility" annotation when the type is declared.

IDL examples:

struct MyType {
long member_1;
} //@Extensibility FINAL_EXTENSIBILITY
struct MyType {
long member_1;
} //@Extensibility EXTENSIBLE_EXTENSIBILITY
struct MyType {
long member_1;
} //@Extensibility MUTABLE_EXTENSIBILITY

XML example:

<struct name="MyType" extensibility="final">
<member name="member_1" type="long"/>
</struct>
<struct name="MyType" extensibility="extensible">
<member name="member_1" type="long"/>
</struct>
<struct name="MyType" extensibility="mutable">
<member name="member_1" type="long"/>
</struct>

XSD example:

<xsd:complexType name="MyType">
<xsd:sequence>
<xsd:element name="member_1" minOccurs="1" maxOccurs="1" type="xsd:int"/>
</xsd:sequence>
</xsd:complexType>
<!-- @struct true -->
<!-- @extensibility FINAL_EXTENSIBILITY -->
<xsd:complexType name="MyType">
<xsd:sequence>
<xsd:element name="member_1" minOccurs="1" maxOccurs="1" type="xsd:int"/>
</xsd:sequence>
</xsd:complexType>
<!-- @struct true -->
<!-- @extensibility EXTENSIBLE_EXTENSIBILITY -->
<xsd:complexType name="MyType">
<xsd:sequence>
<xsd:element name="member_1" minOccurs="1" maxOccurs="1" type="xsd:int"/>
</xsd:sequence>
</xsd:complexType>
<!-- @struct true -->
<!-- @extensibility MUTABLE_EXTENSIBILITY -->

For TypeCodes built at run-time using the com.rti.dds.typecode.TypeCodeFactory API, the extensibility can be provided as a parameter of the following APIs:

com.rti.dds.typecode.ExtensibilityKind
MT Safety:
SAFE.
Returns
The type code extensibility kind.
boolean equal ( TypeCode  tc)

Compares two com.rti.dds.typecode.TypeCode objects for equality.

MT Safety:
SAFE.

For equality and assignability purposes, com.rti.dds.typecode.TCKind.TK_STRUCT and com.rti.dds.typecode.TCKind.TK_VALUE are considered equivalent.

The com.rti.dds.typecode.TypeCode of structs inheriting from other structs has a com.rti.dds.typecode.TCKind.TK_VALUE kind.

For example:

struct MyStruct: MyBaseStruct {
long member_1;
};

The code generation for the previous type will generate a com.rti.dds.typecode.TypeCode with com.rti.dds.typecode.TCKind.TK_VALUE kind.

Parameters
tc<<in>> Type code that will be compared with this com.rti.dds.typecode.TypeCode.
Exceptions
com.rti.dds.infrastructure.ExceptionCode_t.BAD_PARAMif tc is null.
Returns
com.rti.dds.infrastructure.true if the type codes are equal. Otherwise, com.rti.dds.infrastructure.false.
See Also
http://java.sun.com/javase/6/docs/api/org/omg/CORBA/TypeCode.html#equal(org.omg.CORBA.TypeCode)
boolean equals ( Object  tc)

Compares two com.rti.dds.typecode.TypeCode objects for equality.

MT Safety:
SAFE.
Parameters
tc<<in>> Type code that will be compared with this com.rti.dds.typecode.TypeCode.
Returns
com.rti.dds.infrastructure.true if the type codes are equal. Otherwise, com.rti.dds.infrastructure.false.
See Also
http://java.sun.com/javase/6/docs/api/java/lang/Object.html#equals(java.lang.Object)
boolean assignable ( TypeCode  from)

Checks if this com.rti.dds.typecode.TypeCode is assignable from the input com.rti.dds.typecode.TypeCode.

MT Safety:
SAFE.

This method checks if this type code is assignable from the type code provided as a parameter.

In order to maintain the loose coupling between data producers and consumers, especially as systems change over time, it is desirable that the two be permitted to use slightly different versions of a type, and that the infrastructure perform any necessary translation. To support type evolution and inheritance the type system defines the "is-assignable-from" directed binary relationship between every pair of types in the Type System.

Intuitively, if T1 is-assignable-from T2, it means that in general it is possible, in a structural way, to set the contents of an object of type T1 to the contents of an object of T2 (or perhaps a subset of those contents) without leading to incorrect interpretations of that information.

For example:

struct MyBaseType {
long member_1;
};
struct MyDerivedType: MyBaseType {
long member_2;
};

The previous two types that are related to each other by an inheritance relationship are assignable.

For additional information on type assignability refer to the OMG Extensible and Dynamic Topic Types for DDS Specification.

Parameters

Returns
com.rti.dds.infrastructure.true if the "this" is assignable from "from". Otherwise, com.rti.dds.infrastructure.false.

Calling this method clones the type code passed as the tc parameter if the type code is not a builtin one. To delete this cloned type code, call com.rti.dds.typecode.TypeCodeFactory.delete_tc.

The ability to modify a com.rti.dds.typecode.TypeCode – such as by adding a member – is important if you are using the Dynamic Data APIs.

Here's a simple code example that adds two fields to a data type, one an integer and another a sequence of integers.

// Integer:
myTypeCode.add_member(
"myFieldName",
TypeCode.MEMBER_ID_INVALID,
TypeCode.TC_LONG,
// New field is a required non-key member:
TypeCode.NONKEY_REQUIRED_MEMBER);
// Sequence of 10 or fewer integers:
myTypeCode.add_member(
"myFieldName",
TypeCode.MEMBER_ID_INVALID,
TypeCodeFactory.get_instance().create_sequence_tc(10, TypeCode.TC_LONG),
// New field is a required non-key member:
TypeCode.NONKEY_REQUIRED_MEMBER);
MT Safety:
UNSAFE.

A sentinel indicating an invalid com.rti.dds.typecode.TypeCode member index.

final byte NONKEY_MEMBER
static

A flag indicating that a type member is optional and not part of the key.

If a type is used with the Dynamic Data facility, a com.rti.dds.dynamicdata.DynamicData sample of the type will only contain a value for a com.rti.dds.typecode.TypeCode.NONKEY_MEMBER field if one has been explicitly set (see, for example, com.rti.dds.dynamicdata.DynamicData.DynamicData.set_int). The middleware will not assume any default value.
