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.

Basic Settings

	<<basic>> <<spec>> Duration of the deadline period.
dds::core::policy::Ownership	kind
	<<basic>> <<spec>> The kind of ownership
dds::core::policy::Liveliness	kind
	<<basic>> <<spec>> The kind of liveliness desired.
dds::core::policy::Liveliness	lease_duration
	<<basic>> <<spec>> The duration within which a dds::pub::DataWriter must be asserted, or else it is assumed to be not alive.
dds::core::policy::Partition	name
	<<basic>> <<spec>> A list of partition names

Advanced Settings

rti::core::CompressionSettings	compression_ids
	<<extension>> Mask that represents the compression algorithms enabled.
dds::core::policy::DataRepresentation	value
	<<spec>> Sequence of representation identifiers.
