Detailed Description

Indicates whether or not a sample has ever been read.

For each sample received, the middleware internally maintains a sample_state relative to each com.rti.dds.subscription.DataReader. The sample state can be either:

  • com.rti.dds.subscription.SampleStateKind.SampleStateKind.READ_SAMPLE_STATE indicates that the com.rti.dds.subscription.DataReader has already accessed that sample by means of a read or take operation.

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