com.fr.third.jgroups.protocols.SHARED_LOOPBACK_PING

public class SHARED_LOOPBACK_PING
extends Discovery

Discovery protocol running over SHARED_LOOPBACK only. Doesn't send discovery requests and responses, but fetches discovery information directly from SHARED_LOOPBACK. Used mainly by unit test.

方法详细资料

init

public void init()
          throws java.lang.Exception

从类复制的说明: Protocol

Called after instance has been created (null constructor) and before protocol is started. Properties are already set. Other protocols are not yet connected and events cannot yet be sent.

覆盖:

init 在类中 Discovery

抛出:

java.lang.Exception - Thrown if protocol cannot be initialized successfully. This will cause the ProtocolStack to fail, so the channel constructor will throw an exception

isDynamic

public boolean isDynamic()

指定者:

isDynamic 在类中 Discovery

findMembers

public void findMembers(java.util.List<Address> members,
               boolean initial_discovery,
               Responses responses)

从类复制的说明: Discovery

Fetches information (e.g. physical address, logical name) for the given member addresses. Needs to add responses to the Responses object. If Discovery.async_discovery is true, this method will be called in a separate thread, otherwise the caller's thread will be used.

指定者:

findMembers 在类中 Discovery

参数:

members - A list of logical addresses (typically UUIDs). If null, then information for all members is fetched

initial_discovery - Set to true if this is for the initial membership discovery. Some protocols (e.g. file based ones) may return only the information for the coordinator(s).

responses - The list to which responses should be added
