Detailed Description

DDS_InstanceStateKind and associated elements

Typedef Documentation

A bit-mask (list) of instance states, i.e. DDS_InstanceStateKind.

Enumeration Type Documentation

Indicates is the samples are from a live DDS_DataWriter or not.

For each instance, the middleware internally maintains an instance state. The instance state can be:

Enumerator
DDS_ALIVE_INSTANCE_STATE 

Instance is currently in existence.

DDS_NOT_ALIVE_DISPOSED_INSTANCE_STATE 

Not alive disposed instance. The instance has been disposed by a DataWriter.

DDS_NOT_ALIVE_NO_WRITERS_INSTANCE_STATE 

Not alive no writers for instance. None of the DDS_DataWriter objects are currently alive (according to the LIVELINESS) are writing the instance.

Variable Documentation

const DDS_InstanceStateMask DDS_ANY_INSTANCE_STATE

Any instance state ALIVE_INSTANCE_STATE | NOT_ALIVE_DISPOSED_INSTANCE_STATE | NOT_ALIVE_NO_WRITERS_INSTANCE_STATE.

const DDS_InstanceStateMask DDS_NOT_ALIVE_INSTANCE_STATE

Not alive instance state NOT_ALIVE_DISPOSED_INSTANCE_STATE | NOT_ALIVE_NO_WRITERS_INSTANCE_STATE.
