Interface Variable<X>

All Superinterfaces:

javolution.lang.Reference<X>

All Known Implementing Classes:

Variable.Global, Variable.Local

public interface Variable<X>
extends javolution.lang.Reference<X>

This interface represents a symbol on whose value a Function depends. If the functions is not shared between multiple-threads the simple Variable.Local implementation can be used. For global functions (functions used concurrently by multiple threads) the Variable.Global implementation with context-local settings is recommended.
