Method Details

commit

ITransactionalOperation commit()

Returns an ITransactionalOperation that performs all manipulations applied by the policy since the previous init() call.

Returns:

An ITransactionalOperation that performs all manipulations applied by the policy since the last init() call.

getHost

default IVisualPart<? extends javafx.scene.Node> getHost()

Returns the host of this IPolicy, i.e. the IVisualPart this IPolicy is attached to.

Returns:

The host of this IPolicy.

init

void init()

Initializes the policy, so that the policy's "work" methods can be used. Calling a "work" method while the policy is not initialized will result in an IllegalStateException, as well as re-initializing before committing or rolling back.

rollback

void rollback()

Puts back this policy into an uninitialized state, reverting any changes that have been applied via the policy's work methods since the preceding init() call.
