parseLite

protected void parseLite()
                  throws ProtocolException

Description copied from class: Message

Perform the most minimal parse possible to calculate the length of the message. This is only required for subclasses of ChildClass as root level messages will have their length passed into the constructor.

Implementations should adhere to the following contract: If parseLazy = true the 'length' field must be set before returning. If parseLazy = false the length field must be set either within the parseLite() method OR the parse() method. The overriding requirement is that length must be set to non UNKNOWN_MESSAGE value by the time the constructor exits.

Specified by:

parseLite in class Message

Throws:

ProtocolException

parse

public void parse()
           throws ProtocolException

Throws:

ProtocolException

bitcoinSerializeToStream

public void bitcoinSerializeToStream(OutputStream stream)
                              throws IOException

Description copied from class: Message

Serializes this message to the provided stream. If you just want the raw bytes use bitcoinSerialize().

Throws:

IOException

equals

public boolean equals(Object o)

Overrides:

equals in class Object
