                 throws I2NPMessageException

Description copied from interface: I2NPMessage

Read the body into the data structures, after the initial type byte and the uniqueId / expiration, using the current class's format as defined by the I2NP specification

Parameters:

data - data to read from

offset - where to start in the data array

dataSize - how long into the data to read

type - I2NP message type
