Matching

These QoS affect participant and endpoint matching.

These QoS affect participant and endpoint matching.

See the pages of each individual QoS for a desription of how the QoS must be set in order for two applications to be considered matching. Look for information about compatibility or request-offered (RxO) semantics.

DDS_DurabilityQosPolicy	kind
	<<basic>> <<spec>> The kind of durability.
DDS_CompressionSettings_t	compression_ids
	<<extension>> Mask that represents the compression algorithms enabled.
DDS_DataRepresentationQosPolicy	value
	<<spec>> Sequence of representation identifiers.
DDS_DataRepresentationQosPolicy	compression_settings
	<<basic>> <<extension>> Structure that contains the compression settings.
DDS_PresentationQosPolicy	access_scope
	<<spec>> Determines the largest scope spanning the entities for which the order and coherency of changes can be preserved.
DDS_PresentationQosPolicy	coherent_access
	<<spec>> Specifies support for coherent access. Controls whether coherent access is supported within the scope access_scope.
DDS_PresentationQosPolicy	ordered_access
	<<spec>> Specifies support for ordered access to the samples received at the subscription end. Controls whether ordered access is supported within the scope access_scope.

	<<basic>> <<spec>> The kind of liveliness desired.
DDS_LivelinessQosPolicy	lease_duration
	<<basic>> <<spec>> The duration within which a DDS_DataWriter must be asserted, or else it is assumed to be not alive.
