de.dante.extex.interpreter.type.dimen
Class ImmutableDimen

java.lang.Object
  extended byde.dante.extex.interpreter.type.glue.GlueComponent
      extended byde.dante.extex.interpreter.type.dimen.Dimen
          extended byde.dante.extex.interpreter.type.dimen.ImmutableDimen
All Implemented Interfaces:
FixedDimen, FixedGlueComponent, java.io.Serializable
public class ImmutableDimen
extends Dimen
implements java.io.Serializable

This class provides objects of type Dimen where all assignment methods are redefined to produce a run-time exception. Thus the object is in fact immutable.
