java.lang.Object

com.vividsolutions.jump.util.Block

public abstract class Block
extends java.lang.Object

Simply a chunk of code that can be passed around. Facilitates Smalltalk-like programming. Also useful as a "lexical closure" i.e. a chunk of code with variables having long lifetimes.

Typically only one of the #yield methods needs to be implemented. Which one depends on the context.
