Typedef Documentation

◆ DDS_SampleStateMask

A bit-mask (list) of sample states, i.e. DDS_SampleStateKind.

Enumeration Type Documentation

◆ DDS_SampleStateKind

Indicates whether or not a sample has ever been read.

For each sample received, the middleware internally maintains a sample_state relative to each DDSDataReader. The sample state can be either:

The sample state will, in general, be different for each sample in the collection returned by read or take.

Enumerator
DDS_READ_SAMPLE_STATE 

Sample has been read.

DDS_NOT_READ_SAMPLE_STATE 

Sample has not been read.
