<<interface>> Conditions specifically dedicated to read operations and attached to one DDS::DataReader.
DDS::ReadCondition objects allow an application to specify the data samples it is interested in (by specifying the desired sample_states
, view_states
as well as instance_states
in DDS::TypedDataReader::read and DDS::TypedDataReader::take variants.
This allows RTI Connext to enable the condition only when suitable information is available. They are to be used in conjunction with a WaitSet as normal conditions.
More than one DDS::ReadCondition may be attached to the same DDS::DataReader.
Note: If you are using a ReadCondition simply to detect the presence of new data, consider using a DDS::StatusCondition with the DATA_AVAILABLE_STATUS instead, which will perform better in this situation.
System::UInt32 DDS::ReadCondition::get_sample_state_mask | ( | ) |
Retrieves the set of sample_states
for the condition.
System::UInt32 DDS::ReadCondition::get_view_state_mask | ( | ) |
Retrieves the set of view_states
for the condition.
System::UInt32 DDS::ReadCondition::get_instance_state_mask | ( | ) |
Retrieves the set of instance_states
for the condition.
DataReader ^ DDS::ReadCondition::get_datareader | ( | ) |
Returns the DDS::DataReader associated with the DDS::ReadCondition.
There is exactly one DDS::DataReader assicated with each DDS::ReadCondition.
