Detailed Description

DDSTopic entity and associated elements

Typedef Documentation

typedef struct DDS_PrintFormatProperty DDS_PrintFormatProperty

A collection of attributes used to configure how data samples will be formatted when converted to a string.

Enumeration Type Documentation

enum DDS_PrintFormatKind

Format kinds available when converting data samples to string representations.

Enumerator:

DDS_DEFAULT_PRINT_FORMAT	Use a default format specific to RTI Connext to represent the data when converting to a string.
DDS_XML_PRINT_FORMAT	Use an XML format to represent the data when converting to a string.
DDS_JSON_PRINT_FORMAT	Use a JSON format to represent the data when converting to a string.

Function Documentation

DDS_Boolean DDS_TopicQos_equals	(	const struct DDS_TopicQos *	self,
		const struct DDS_TopicQos *	other
	)

Compares two DDS_TopicQos for equality.

Parameters

self	<<in>> This TopicQos.
other	<<in>> The other TopicQos to be compared with this TopicQos

Returns

DDS_BOOLEAN_TRUE if the two Qos objects are equal or DDS_BOOLEAN_FALSE otherwise.

Referenced by DDS_TopicQos::operator!=(), and DDS_TopicQos::operator==().

Variable Documentation

struct DDS_PrintFormatProperty DDS_PRINT_FORMAT_PROPERTY_DEFAULT

Sentinel constant indicating default values for DDS_PrintFormatProperty.

Pass this object instead of your own DDS_PrintFormatProperty object to use the default property values:

retCode = FooTypeSupport::data_to_string( 
     sample, 
     DDS_PRINT_FORMAT_PROPERTY_DEFAULT);
