Class ScriptBuilder

java.lang.Object
  com.google.bitcoin.script.ScriptBuilder

public class ScriptBuilder
extends Object

Tools for the construction of commonly used script types. You don't normally need this as it's hidden behind convenience methods on Transaction, but they are useful when working with the protocol at a lower level.
