Detailed Description

A list of data representations supported by a DDS_DataWriter or DDS_DataReader.

Typedef Documentation

typedef DDS_Short DDS_DataRepresentationId_t

A two-byte signed integer that identifies a data representation.

Variable Documentation

const DDS_DataRepresentationId_t DDS_XCDR_DATA_REPRESENTATION

Corresponds to the Extended Common Data Representation encoding version 1.

const DDS_DataRepresentationId_t DDS_XML_DATA_REPRESENTATION

Corresponds to the XML Data Representation (unsupported).

Note

This value is currently not supported.

const DDS_DataRepresentationId_t DDS_XCDR2_DATA_REPRESENTATION

Corresponds to the Extended Common Data Representation encoding version 2.

const DDS_DataRepresentationId_t DDS_AUTO_DATA_REPRESENTATION

Representation is automatically chosen based on the type.

For plain language binding, if the allow_data_representation annotation is not specified or if it contains the value XCDR, RTI Connext translates this field to DDS_XCDR_DATA_REPRESENTATION. Otherwise, it translates this field to DDS_XCDR2_DATA_REPRESENTATION.

For the FlatData language binding, RTI Connext translates this field to DDS_XCDR2_DATA_REPRESENTATION.

Examples:

HelloWorldPlugin.c.

const char* const DDS_DATA_REPRESENTATION_QOS_POLICY_NAME

Stringified human-readable name for DDS_DataRepresentationQosPolicy.
