Public Attributes | |
SampleIdentity_t | related_sample_identity |
The identity of another sample related to this one. | |
GUID_t | related_source_guid |
Identifies the application logical data source that is related to the sample being written. | |
GUID_t | related_reader_guid |
Identifies a DataReader that is logically related to the sample. | |
Properties | |
static System::Int32 | PRIORITY_UNDEFINED [get] |
Initializer value for DDS::PublishModeQosPolicy::priority and/or DDS::ChannelSettings_t::priority. | |
static System::Int32 | PRIORITY_AUTOMATIC [get] |
Constant value for DDS::PublishModeQosPolicy::priority and/or DDS::ChannelSettings_t::priority. | |
Provides meta information associated with the sample.
This can be used by a content filter to perform filtering on meta data.
SampleIdentity_t DDS::FilterSampleInfo::related_sample_identity |
The identity of another sample related to this one.
The value of this field identifies another sample that is logically related to the one that is written. For example, the DDS::DataWriter created by a Replier uses this field to associate the identity of the request sample with a reponse sample.
To specify that there is no related sample identity, use the value DDS::SampleIdentity_t::UNKNOWN_SAMPLE_IDENTITY.
A DDS::DataReader can inspect the related sample identity of a received sample by accessing the fields DDS::SampleInfo::related_original_publication_virtual_guid and DDS::SampleInfo::related_original_publication_virtual_sequence_number.
GUID_t DDS::FilterSampleInfo::related_source_guid |
Identifies the application logical data source that is related to the sample being written.
The related_source_guid can be set by using the field DDS::WriteParams_t::related_source_guid when writing a sample using the method DDS::TypedDataWriter::write_w_params.
GUID_t DDS::FilterSampleInfo::related_reader_guid |
Identifies a DataReader that is logically related to the sample.
The related_reader_guid can be set by using the field DDS::WriteParams_t::related_reader_guid when writing a sample using the method DDS::TypedDataWriter::write_w_params.
