Constant Field Values

Method Detail

name

String name()

Returns the name of this primitive.

Returns:

name

primitiveType

DistributedPrimitive.Type primitiveType()

Returns the type of primitive.

Returns:

primitive type

applicationId

default ApplicationId applicationId()

Returns the application owning this primitive.

Returns:

application id

destroy

default CompletableFuture<Void> destroy()

Purges state associated with this primitive.

Implementations can override and provide appropriate clean up logic for purging any state state associated with the primitive. Whether modifications made within the destroy method have local or global visibility is left unspecified.

Returns:

CompletableFuture that is completed when the operation completes

addStatusChangeListener

default void addStatusChangeListener(Consumer<DistributedPrimitive.Status> listener)

Registers a listener to be called when the primitive's status changes.

Parameters:

listener - The listener to be called when the status changes.

removeStatusChangeListener

default void removeStatusChangeListener(Consumer<DistributedPrimitive.Status> listener)

Unregisters a previously registered listener to be called when the primitive's status changes.

Parameters:

listener - The listener to unregister

statusChangeListeners

default Collection<Consumer<DistributedPrimitive.Status>> statusChangeListeners()

Returns the collection of status change listeners previously registered.

Returns:

collection of status change listeners
