Class UTXO

java.lang.Object

org.bitcoinj.core.UTXO

All Implemented Interfaces:

java.io.Serializable

public class UTXO
extends java.lang.Object
implements java.io.Serializable

A UTXO message contains the information necessary to check a spending transaction. It avoids having to store the entire parentTransaction just to get the hash and index. Useful when working with free standing outputs.
