Method Details

doStep

public void doStep()

Description copied from class: Context

If Context has a concrete execution step to perform, it should happen in this method. This should not include setting up next steps (i.e., children to perform), which should happen in the setupNextStep method. Primitive actions and operators (i.e., leaf nodes in the context tree) are examples where this method should be implemented.

Overrides:

doStep in class Context

copy

public OperatorContext 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
