Class RemoveAction

java.lang.Object

All Implemented Interfaces:

IAction, IBufferAction, ISlotContainer

public class RemoveAction
extends ModifyAction
implements IBufferAction

The remove action does just that. It removes a chunk from a named buffer. Since buffers currently only contain one chunk, remove needs not specify anything other than the buffer name. If the named buffer doesn?t contain a chunk, no action is taken.

Method Detail

bind

public IAction bind(java.util.Map<java.lang.String,java.lang.Object> variableBindings)
             throws CannotInstantiateException

Description copied from interface: IAction

Bind is called during the creation of an instantiation of a produciton. By the time this gets called, we know that all the conditions are matched and all the variables have been assigned. This method merely creates a copy of this action and applies those bindings. the IAction returned by this method will be the actual one that is fired. Normally, an action should not change the contents of variableBindings

Specified by:

bind in interface IAction

Overrides:

bind in class ModifyAction

Returns:

Throws:

CannotInstantiateException

fire

public double fire(IInstantiation instantiation,
                   double firingTime)

post an event that will remove the contents of the buffer. We post an event because this is SOP.

Specified by:

fire in interface IAction

Overrides:

fire in class ModifyAction

Parameters:

instantiation - Description of the Parameter

firingTime - when this production was fired

Returns:

Description of the Return Value
