doReadMessage

protected void doReadMessage(InputStream in,
 int size)
                      throws I2CPMessageException,
IOException

Description copied from class: I2CPMessageImpl

Read in the payload part of the message (after the initial 4 byte size and 1 byte type)

Specified by:

doReadMessage in class I2CPMessageImpl

Parameters:

in - InputStream

size - payload size

Throws:

I2CPMessageException

IOException

readMessage

public void readMessage(InputStream in,
 int length,
 int type)
                 throws I2CPMessageException,
IOException

Read the body into the data structures

Specified by:

readMessage in interface I2CPMessage

Overrides:

readMessage in class I2CPMessageImpl

Parameters:

in - stream to read from

length - number of bytes in the message payload

type - type of message (should equal getType())

Throws:

IOException

I2CPMessageException - if the stream doesn't contain a valid message that this class can read.
