canDeploy

public boolean canDeploy(int deploySequenceId)

Description copied from interface: Deployer

Indicate whether the deployer (or if its a composite deployer then any of its contained deployers) is capable of deploying the task indicated by the DeploymentSequenceId. This method is called by the framework to co-ordinate and resolve deployment events.

Specified by:

canDeploy in interface Deployer

Returns:

true if the deployer can deploy the sequence.

initializeState

public void initializeState()

Description copied from interface: Stateful

Transition from 'Uninitialized' to 'Initialized'.

Specified by:

initializeState in interface Stateful

invalidateState

public void invalidateState()

Description copied from interface: Stateful

Transition from 'Valid' to 'Initialized' state. When 'operation' is performed, the state transition to valid again.

Specified by:

invalidateState in interface Stateful

releaseState

public void releaseState()

Description copied from interface: Stateful

Release state and any resources its holding.

Specified by:

releaseState in interface Stateful
