DataReader Methods |
The DataReader type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | CreateQueryCondition(String, String) |
Creates a QueryCondition to read samples with any sample states, any view states and any instance states.
|
| CreateQueryCondition(SampleStateMask, ViewStateMask, InstanceStateMask, String, String) |
Creates a QueryCondition with the desired sample states, view states and instance states.
|
| CreateReadCondition |
Creates a ReadCondition to read samples with any sample states, any view states and any instance states.
|
| CreateReadCondition(SampleStateMask, ViewStateMask, InstanceStateMask) |
Creates a ReadCondition to read samples with the desired sample states, view states and instance states.
|
| DeleteContainedEntities |
Deletes all the entities that were created by means of the "create" operations on the DataReader. That is, it
deletes all contained ReadCondition and QueryCondition objects.
|
| DeleteReadCondition |
Deletes a ReadCondition attached to the DataReader. Since QueryCondition specializes ReadCondition it can
also be used to delete a QueryCondition.
|
| Enable |
Enables the Entity. The enable operation is idempotent. Calling enable on an already enabled Entity returns
Ok and has no effect.
(Inherited from Entity.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetListener |
Allows access to the attached DataReaderListener.
|
| GetLivelinessChangedStatus |
Allows access to the LivelinessChangedStatus communication status.
|
| GetMatchedPublicationData |
This operation retrieves information on a publication that is currently "associated" with the DataReader; that is, a publication
with a matching Topic and compatible QoS that the application has not indicated should be "ignored" by means of the
DomainParticipant IgnorePublication operation.
|
| GetMatchedPublications |
Gets the list of publications currently "associated" with the DataReader; that is, publications that have a
matching Topic and compatible QoS that the application has not indicated should be "ignored" by means of the
DomainParticipant IgnorePublication operation.
|
| GetQos |
Gets the DataReader QoS policies.
|
| GetRequestedDeadlineMissedStatus |
Allows access to the RequestedDeadlineMissedStatus communication status.
|
| GetRequestedIncompatibleQosStatus |
Allows access to the RequestedIncompatibleQosStatus communication status.
|
| GetSampleLostStatus |
Allows access to the SampleLostStatus communication status.
|
| GetSampleRejectedStatus |
Allows access to the SampleRejectedStatus communication status.
|
| GetSubscriptionMatchedStatus |
Allows access to the SubscriptionMatchedStatus communication status.
|
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| SetListener(DataReaderListener) |
Sets the DataReaderListener using the DefaultStatusMask.
|
| SetListener(DataReaderListener, StatusMask) |
Sets the DataReaderListener.
|
| SetQos |
Sets the DataReader QoS policies.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| WaitForHistoricalData |
Waits until all "historical" data is received.
This operation is intended only for DataReader entities that have a non-Volatile DurabilityQosPolicyKind.
