length

public int length()
Returns the total length, in bytes, of this structure.
Specified by:
length in interface Handshake.Body
length in interface Constructed
Returns:
The length of this structure.

random

public Random random()
Gets the SSL nonce.
Returns:
The nonce.

sessionId

public byte[] sessionId()

toString

public String toString()
Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() and such.

It is typical, but not required, to ensure that this method never completes abruptly with a RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

Overrides:
toString in interface Object
Returns:
the String representing this Object, which may be null

toString

public String toString(String prefix)
Returns a printable representation of this structure, with the given prefix prepended to each line.
Specified by:
toString in interface Handshake.Body
toString in interface Constructed
Parameters:
prefix - The prefix to prepend to each line of the output. This value may be null.
Returns:
A printable representation of this structure.

version

public ProtocolVersion version()
Gets the protocol version field.
Returns:
The protocol version field.
