calculate the message body's length (not including the header and footer

Overrides:

calculateWrittenLength in class TunnelBuildMessageBase

getType

public int getType()

Description copied from interface: I2NPMessage

Return the unique identifier for this type of I2NP message, as defined in the I2NP spec

Specified by:

getType in interface I2NPMessage

Overrides:

getType in class TunnelBuildMessage

readMessage

public void readMessage(byte[] data,
                        int offset,
