AbstractContinuationState

public AbstractContinuationState()

Method Detail

getChildContState

public ContinuationState getChildContState()

Get the child ContinuationState

Specified by:

getChildContState in interface ContinuationState

Returns:

child ContinuationState

setChildContState

public void setChildContState(ContinuationState childContState)

Set the child ContinuationState. Child ContinuationState is added when branching the flow using all FlowContinuableMediators except Sequence Mediator.

Specified by:

setChildContState in interface ContinuationState

Parameters:

childContState - ContinuationState to be added as the child

getPosition

public int getPosition()

Get the position of the mediator in the current flow.

Specified by:

getPosition in interface ContinuationState

Returns:

position

setPosition

public void setPosition(int position)

Set the position of the mediator in the flow which is currently being processed. Position should be updated only when branching to a new flow (i.e. not necessary to update for each and every mediator execution in the flow)

Specified by:

setPosition in interface ContinuationState

Parameters:

position - position of the mediator which is currently being processed in the flow.

hasChild

public boolean hasChild()

Check whether child ContinuationState exists

Specified by:

hasChild in interface ContinuationState

Returns:

whether child ContinuationState exists

getLeafChild

public ContinuationState getLeafChild()

Get the Leaf Child of this ContinuationState. When mediate using the ContinuationStateStack, first we start from the Lead Child of the ContinuationState.

Specified by:

getLeafChild in interface ContinuationState

Returns:

Leaf child of the ContinuationState

addLeafChild

public void addLeafChild(ContinuationState leafChild)

Add a Leaf child to this ContinuationState

Specified by:

addLeafChild in interface ContinuationState

Parameters:

leafChild - ContinuationState which can be added as a Leaf child for this SeqContinuationState

removeLeafChild

public void removeLeafChild()

Remove the Leaf child form this ContinuationState.

Specified by:

removeLeafChild in interface ContinuationState
