DataWriterAssertLiveliness Method

Manually asserts the liveliness of the DataWriter. This is used in combination with the liveliness QoS policy to indicate to DDS that the entity remains active.

Namespace: OpenDDSharp.DDS
Assembly: OpenDDSharp (in OpenDDSharp.dll) Version: 0.5.0.0

Syntax

Copy

public ReturnCode AssertLiveliness()

Public Function AssertLiveliness As ReturnCode

public:
ReturnCode AssertLiveliness()

member AssertLiveliness : unit -> ReturnCode

Return Value

Type: ReturnCode
The ReturnCode that indicates the operation result.

Remarks

This operation need only be used if the LivelinessQosPolicy setting is either ManualByParticipantLivelinessQos or ManualByTopicLivelinessQos. Otherwise, it has no effect.

NOTE: Writing data via the write operation on a DataWriter asserts liveliness on the DataWriter itself and its DomainParticipant. Consequently the use of AssertLiveliness is only needed if the application is not writing data regularly.
