Method Summary

Modifier and Type	Method	Description
ForeachContext	copy(Context newParent)	deep copy of the context, its status, and its children
protected void	resetConcreteContext()	This resets fields specific to concrete sub-classes and should be overridden by inheriting classes if additional resetting needs to happen.
protected void	setupArguments(List<? extends Object> inputArgs, List<? extends Object> returnArgs)	Sets up the variable for the "foreach" context.
protected void	setupNextStep()	If Context can have next steps (i.e., children), implement this method to add the next child context that should be executed.

 List<? extends Object> returnArgs)

Sets up the variable for the "foreach" context.

Specified by:

setupArguments in class ArgumentBasedContext

Parameters:

inputArgs - should be 2 arguments: element and collection

resetConcreteContext

protected void resetConcreteContext()

Description copied from class: Context

This resets fields specific to concrete sub-classes and should be overridden by inheriting classes if additional resetting needs to happen.

Overrides:

resetConcreteContext in class Context

copy

public ForeachContext copy(Context newParent)

Description copied from class: Context

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

Specified by:

copy in class Context
