Additional Inherited Members | |
 Public Member Functions inherited from DDS::DataReader | |
| InstanceHandle_t | get_instance_handle () |
| This operation returns the InstanceHandle_t that identifies the DataReader. | |
| StatusMask | get_status_changes () |
| This returns the list of triggered communication statuses in the DataReader. More... | |
| ReturnCode_t | enable () |
| Enables the DataReader. More... | |

| ReturnCode_t | delete_readcondition (ReadCondition *a_condition) |
| Destroys a ReadCondition (or QueryCondition). More... | |
| ReturnCode_t | delete_contained_entities () |
| This operation deletes all the ReadCondition and QueryCondition objects previously created by means of the DataReader_create_readcondition() and DataReader_create_querycondition() operations. More... | |

| ReturnCode_t | set_listener (DataReaderListener *a_listener, StatusMask mask) |
| Installs a DataReaderListener on DataReader dr. More... | |
| DataReaderListener * | get_listener () |
