Detailed Description

<<cert>> A QoS policy for all DDS_Entity types that can act as factories for one or more other DDS_Entity types.

Entity:

DDS_DomainParticipantFactory, DDS_DomainParticipant, DDS_Publisher, DDS_Subscriber

Properties:

RxO = NO
Changeable = YES

Usage

This policy controls the behavior of the DDS_Entity as a factory for other entities.

This policy is mutable. A change in the policy affects only the entities created after the change; not the previously created entities.

The setting of autoenable_created_entities to DDS_BOOLEAN_TRUE indicates that the factory create_<entity> operation will automatically invoke the DDS_Entity_enable operation each time a new DDS_Entity is created. Therefore, the DDS_Entity returned by create_<entity> will already be enabled. A setting of DDS_BOOLEAN_FALSE indicates that the DDS_Entity will not be automatically enabled. The application will need to enable it explicitly by means of DDS_Entity_enable operation.

The default setting of autoenable_created_entities = DDS_BOOLEAN_TRUE means that, by default, it is not necessary to explicitly call DDS_Entity_enable on newly created entities.
