Creates an instance with the default settings.

Member Function Documentation

DataWriterShmemRefTransferModeSettings& rti::core::DataWriterShmemRefTransferModeSettings::enable_data_consistency_check

(

bool

the_enable_data_consistency_check

)

Controls if samples can be checked for consistency.

When this setting is true, the dds::pub::DataWriter sends an incrementing sequence number as an inline QoS with every sample. This sequence number allows a dds::sub::DataReader to use the dds::sub::DataReader::is_data_consistent API to detect if the dds::pub::DataWriter overwrote the sample before the dds::sub::DataReader could complete processing the sample.

[default] true
