groovy.lang
Class Closure.WritableClosure

java.lang.Object
  groovy.lang.GroovyObjectSupport
      groovy.lang.Closure
          groovy.lang.Closure.WritableClosure

All Implemented Interfaces:

GroovyObject, Writable, java.lang.Cloneable, java.lang.Runnable

Enclosing class:

Closure

private class Closure.WritableClosure
extends Closure
implements Writable

Implementation note: This has to be an inner class! Reason: Closure.this.call will call the outer call method, but with the inner class as executing object. This means any invokeMethod or getProperty call will be called on this inner class instead of the outer!
