Method Details

setStatus

public void setStatus(ActionStatus eStatus,
 Justification justification)

Description copied from class: Context

Set the ActionStatus and Justification for the status. NOTE: Classes overriding this method must call super.setStatus(status, justification) inside their overriding method to actually set the status and justification. Using the convenience method setStatus(status) will cause an infinite loop, and also abandon the Justification.

Overrides:

setStatus in class Context

setupNextStep

protected void setupNextStep()

Description copied from class: Context

If Context can have next steps (i.e., children), implement this method to add the next child context that should be executed.

Overrides:

setupNextStep in class Context

copy

public IfContext copy(Context newParent)

Description copied from class: Context

deep copy of the context, its status, and its children

Specified by:

copy in class Context

Parameters:

newParent - parent to attach the copied context too

Returns:

the copied context
