Java In A Nutshell, 5th Edition

The constants defined by this enumerated type specify the handshake status of the SSLEngine and often specify the action your code must take next in order to ensure correct operation. The values are the following:

NOT_HANDSHAKING

Handshaking is not currently in progress.

FINISHED

Handshaking just completed as a result of the wrap( ) or unwrap( ) call that generated this value.

NEED_WRAP

The SSLEngine needs to send more handshake data, so a call to wrap( ) is necessary.

NEED_UNWRAP

The SSLEngine needs to receive more handshake data, so a call to unwrap( ) is necessary.

NEED_TASK

The SSLEngine needs to perform an authentication or related task, so you must repeatedly call getdelegatedTask( ) and run( ) any Runnable objects it returns.

public enum SSLEngineResult.HandshakeStatus { // Enumerated Constants NOT_HANDSHAKING , FINISHED , NEED_TASK , NEED_WRAP , NEED_UNWRAP ; // Public Class Methods public static SSLEngineResult.HandshakeStatus valueOf (String name ); public static final SSLEngineResult.HandshakeStatus[ ] values ( ); }
