Class ConnectionResolver

java.lang.Object
  mx4j.remote.ProviderHelper
      mx4j.remote.ConnectionResolver

Direct Known Subclasses:

HTTPResolver, Resolver, Resolver

public abstract class ConnectionResolver

extends ProviderHelper

ConnectionResolver handles the details of creating connections for different protocols. Subclasses for the specific protocol are instantiated using a mechanism very similar to the one specified by JMXConnectorFactory. Here a subclass has a fully qualified name specified like this: .resolver..Resolver, for example Resolver This class is used from both the client and the server. The former uses it to lookup stubs or connections to the server side; the latter uses it to create server instances and make them availale to clients, for example via JNDI. The client and server methods have not been splitted into 2 different interfaces because most of the times they share common code, although it may have been a better design.

Method Summary

abstract java.lang.Object	bindClient(java.lang.Object client, java.util.Map environment) Connects the client returned by lookupClient(javax.management.remote.JMXServiceURL, java.util.Map) to the server side.
abstract javax.management.remote.JMXServiceURL	bindServer(java.lang.Object server, javax.management.remote.JMXServiceURL url, java.util.Map environment) Binds the server created by createServer(javax.management.remote.JMXServiceURL, java.util.Map) to a place specified by the JMXServiceURL.

Method Detail

newConnectionResolver

public static ConnectionResolver newConnectionResolver(java.lang.String proto,
                                                       java.util.Map environment)

Returns a subclass of ConnectionResolver for the specified protocol.

lookupClient

public abstract java.lang.Object lookupClient(javax.management.remote.JMXServiceURL url,
                                              java.util.Map environment)
                                       throws java.io.IOException

Looks up a connection with the server side as specified in the given JMXServiceURL. This method is used in implementations of JMXConnector.connect().

Throws:

java.io.IOException

bindClient(java.lang.Object, java.util.Map)

bindClient

public abstract java.lang.Object bindClient(java.lang.Object client,
                                            java.util.Map environment)
                                     throws java.io.IOException

Connects the client returned by lookupClient(javax.management.remote.JMXServiceURL, java.util.Map) to the server side.

Returns:

An object of the same type as the client passed in; normally the client object itself

Throws:

java.io.IOException

createServer

public abstract java.lang.Object createServer(javax.management.remote.JMXServiceURL url,
                                              java.util.Map environment)
                                       throws java.io.IOException

Creates an instance of the server as specified in the given JMXServiceURL. It is only a factory method, it should just return a fresh instance of the server; other methods are responsible to make it available to clients (for example exporting it). This method is used in implementations of JMXConnectorServerMBean.start().

Throws:

java.io.IOException

                                                          throws java.io.IOException

Binds the server created by createServer(javax.management.remote.JMXServiceURL, java.util.Map) to a place specified by the JMXServiceURL.

Returns:

a new JMXServiceURL that specifies where the server has been bound to.

Throws:

java.io.IOException

Unbinds the server bound by bindServer(java.lang.Object, javax.management.remote.JMXServiceURL, java.util.Map) from the place specified by the JMXServiceURL.

Throws:

                            throws java.io.IOException
