类 DemoToken

java.lang.Object

com.fr.third.jgroups.auth.AuthToken

com.fr.third.jgroups.auth.DemoToken

所有已实现的接口:

AUTH.UpHandler, Streamable

public class DemoToken
extends AuthToken
implements AUTH.UpHandler

AuthToken implementation which shows how to send messages back and forth in order to perform authentication. Could be used as a template for a challenge-response based AuthToken impl.

从以下版本开始:

方法详细资料

getName

public java.lang.String getName()

从类复制的说明: AuthToken

Used to return the full package and class name of the implementation. This is used by the AUTH protocol to create an instance of the implementation.

指定者:

getName 在类中 AuthToken

返回:

a java.lang.String object of the package and class name

init

public void init()

覆盖:

init 在类中 AuthToken

authenticate

public boolean authenticate(AuthToken token,
                   Message msg)

从类复制的说明: AuthToken

This method should be implemented to perform the actual authentication of joining members.

指定者:

authenticate 在类中 AuthToken

参数:

token - the token sent by the joiner

msg - the Message object containing the actual JOIN_REQ

返回:

true if authenticaion passed or false if it failed.

writeTo

public void writeTo(java.io.DataOutput out)
             throws java.lang.Exception

从接口复制的说明: Streamable

指定者:

writeTo 在接口中 Streamable

抛出:

java.lang.Exception

readFrom

public void readFrom(java.io.DataInput in)
              throws java.lang.Exception

从接口复制的说明: Streamable
