Constructor Detail

MetaConcurrentState

public MetaConcurrentState(String tag,
                           StateAction entry,
                           StateAction exit)

Construct a new MetaConcurrentState given its identifier (tag) and its entry and exit action.

Parameters:

tag - this state identifier

entry - this state entry action. Passing null means no action should be performed

exit - this state exit action. Passing null means no action should be performed

Throws:

NullPointerException - if the tag is null

Method Detail

checkAllowedSubstate

protected void checkAllowedSubstate(MetaState newMetaState)

Verifies that a sub-state of this state is a MetaSequentialState.

Overrides:

checkAllowedSubstate in class MetaCompositeState

Parameters:

newMetaState - the MetaState that shoud be checked

Throws:

IllegalArgumentException - if the parameter cannot be a sub-state of this state

newState

public State newState(CompositeState parent)

Description copied from class: MetaState

Create a new State based on this meta-state. Implementations of this method must call MetaState.checkParentState(CompositeState) to check that the passed state is admittable as parent state for the state that will be created.

Specified by:

newState in class MetaState

Parameters:

parent - the parent state for the state that will be created

Returns:

the new state
