Interface Closure

All Known Implementing Classes:

TclClosure

public interface Closure

A Closure is a snippet of code that can access variables from one context while running in another. Closures are used with Expect4J to define handlers that are executed whenever a corresponding Match is found.

Currently in Java, all variables accessed by the Closure need to be marked as final. To export information from the Closure context to the context in which the Closure is defined, consider using buffers such as final StringBuffer.
