com.fr.third.jgroups.protocols.TCPPING

public class TCPPING
extends Discovery

The TCPPING protocol defines a static cluster membership. The cluster members are retrieved by directly contacting the members listed in initial_hosts, sending point-to-point discovery requests.

The TCPPING protocol defines a static configuration, which requires that you to know in advance where to find all of the members of your cluster.

构造器详细资料

TCPPING

public TCPPING()

方法详细资料

isDynamic

public boolean isDynamic()

指定者:

isDynamic 在类中 Discovery

getInitialHosts

public java.util.List<PhysicalAddress> getInitialHosts()

Returns the list of initial hosts as configured by the user via XML. Note that the returned list is mutable, so careful with changes !

返回:

List

list of initial hosts. This variable is only set after the channel has been created and set Properties() has been called

setInitialHosts

public void setInitialHosts(java.util.List<PhysicalAddress> initial_hosts)

getPortRange

public int getPortRange()

setPortRange

public void setPortRange(int port_range)

getDynamicHostList

public java.lang.String getDynamicHostList()

clearDynamicHostList

public void clearDynamicHostList()

getInitialHostsList

public java.lang.String getInitialHostsList()

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

down

public java.lang.Object down(Event evt)

从类复制的说明: Protocol

An event is to be sent down the stack. The layer may want to examine its type and perform some action on it, depending on the event's type. If the event is a message MSG, then the layer may need to add a header to it (or do nothing at all) before sending it down the stack using down_prot.down(). In case of a GET_ADDRESS event (which tries to retrieve the stack's address from one of the bottom layers), the layer may need to send a new response event back up the stack using up_prot.up().

覆盖:

down 在类中 Discovery

discoveryRequestReceived

public void discoveryRequestReceived(Address sender,
                            java.lang.String logical_name,
                            PhysicalAddress physical_addr)

覆盖:

discoveryRequestReceived 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
