Constructor Detail

InterpreterWrapper

public InterpreterWrapper()

Create an empty wrapper.

InterpreterWrapper

public InterpreterWrapper(Interpreter newintrp)

Wrap an interpreter into this wrapper.

Method Detail

setInterpreter

public Interpreter setInterpreter(Interpreter newintrp)

Set what the wrapped-up interpreter is.

setAttachedGraphicalObject

public GraphicalObject setAttachedGraphicalObject(GraphicalObject newGob)

Overrided to set the GraphicalObject for the wrapped-up interpreter too.

Overrides:

setAttachedGraphicalObject in class InterpreterImpl

Following copied from class: edu.berkeley.guir.lib.satin.interpreter.InterpreterImpl

Parameters:

gob - is the GraphicalObject this Interpreter is to be attached to. Okay if null temporarily.

getInterpreter

public Interpreter getInterpreter()

Get the wrapped-up interpreter.

isEnabled

public boolean isEnabled()

Description copied from interface: Interpreter

See if this interpreter is enabled or not (ie can run or not). This is used by the GraphicalObject and by MultiInterpreter before delegating any calls to the Interpreter.

If called by an MultiInterpreter, it just turns that MultiInterpreter off, but not any contained Interpreters.

Overrides:

isEnabled in class InterpreterImpl

toString

public String toString()

Overrides:

toString in class InterpreterImpl

clone

protected InterpreterWrapper clone(InterpreterWrapper iw)
