getDescription

public String getDescription()

setDescription

public void setDescription(String description)

processExecutionPhase

public void processExecutionPhase(ExecutionContext context)

Called by the Executor to signal a new phase in the execution

Specified by:

processExecutionPhase in interface ExecutionPhaseListener

Parameters:

context -

updateStatusRegion

protected void updateStatusRegion(ExecutionContext context)

Updates the level status panel.

processPoints

protected void processPoints(ExecutionContext context)

Processes the points set by the executable element. This default implementation first mirrors the points as set by the executable element, followed by letting all PointAdaptors set on the executable element as aspects adapt the points as they wish.

updateTotals

protected void updateTotals(ExecutionContext context)

processLevel

protected void processLevel(ExecutionContext context)

Checks for level changes. The actual level check is done by checkLevelChange. This method merely takes care of informing the LevelChangeListeners in case a level change happened.

informLevelChangeListeners

protected void informLevelChangeListeners(ExecutionContext context)

Informs all listeners in the execution stack about a level change.

checkLevelChange

protected abstract int checkLevelChange(ExecutionContext context,
                                        int currentLevel)

Overwrite to implement a different level/points logic. Default logic simply uses += level = > +- 100.

Returns:

the new level. This can be the old level value

initializeHandler

protected abstract void initializeHandler(ExecutionContext context)
