public abstract class FixableProcedure
extends NativeProcedure
implements NamedValue

A fixable procedure is a Scheme procedure similar to a NativeProcedure, but which does not need access to the Interpreter to be implemented, causes no side-effects, and requires three or fewer arguments. In general, most purely functional procedures are fixable.

Method Summary

Value	apply() A fixable procedure must subclass one of the following methods
Value	apply(Value v1)
Value	apply(Value[] v)
Value	apply(Value v1, Value v2)
Value	apply(Value v1, Value v2, Value v3)
