Constructor Detail

ConnectionImpl

protected ConnectionImpl(String[] hosts,
                         String username,
                         String password)
                  throws ConnectionException

Throws:

ConnectionException

Method Detail

setNamespace

public void setNamespace(String namespace)

Description copied from interface: RhinoConnection

Set the current Rhino namespace associated with this connection. This namespace will be set as the active namespace if/when the connection needs to be re-established. Note that this method only affects local state, it does *not* invoke the NamespaceManagementMBean in Rhino to set the current active namespace.

Specified by:

setNamespace in interface RhinoConnection

Parameters:

namespace - the namespace. May be null to indicate the default namespace.

connect

public void connect()
             throws ConnectionException

Description copied from interface: RhinoConnection

Try to connect this connection.

Specified by:

connect in interface RhinoConnection

Throws:

ConnectionException - if the connection attempt failed

disconnect

public void disconnect()

Description copied from interface: RhinoConnection

Disconnect this connection.

Specified by:

disconnect in interface RhinoConnection

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

testConnection

public void testConnection()
                    throws ConnectionException

Description copied from interface: RhinoConnection

Test this connection by invoking a basic MBean operation. If the test fails, an reconnect attempt will be triggered automatically.

Specified by:

testConnection in interface RhinoConnection

Throws:

ConnectionException - if the test failed and the attempt to automatically reconnect failed.

reconnect

public void reconnect()
               throws ConnectionException

Description copied from interface: RhinoConnection

Disconnect then connect this connection.

Specified by:

reconnect in interface RhinoConnection

Throws:

ConnectionException - if the connection attempt failed

getJmxConnector

public JMXConnector getJmxConnector()

Description copied from interface: RhinoConnection

Get the JMXConnector associated with this MBeanServer connection.

Specified by:

getJmxConnector in interface RhinoConnection

Returns:

a JMXConnector instance

getConnectedState

public boolean getConnectedState()

Description copied from interface: RhinoConnection

Whether or not this connection is connected.

Specified by:

getConnectedState in interface RhinoConnection

state of the connection

getServerHost

public String getServerHost()

Description copied from interface: RhinoConnection

The host name of the current connection. Useful if this connection is configured to try multiple hosts.

Specified by:

getServerHost in interface RhinoConnection

Returns:

host where this connection object is currently connected to Rhino

getServerPort

public int getServerPort()

Description copied from interface: RhinoConnection

The port of the current connection. Useful if this connection is configured to try multiple hosts.

Specified by:

getServerPort in interface RhinoConnection

Returns:

port where this connection object is currently connected to Rhino

getServerNodeId

public int getServerNodeId()

Description copied from interface: RhinoConnection

The node ID of the server the current connection is to. Useful if this connection is configured to try multiple hosts.

Specified by:

getServerNodeId in interface RhinoConnection

Returns:

node id of Rhino where this connection object is currently connected to

getServerRhinoVersion

public RhinoVersion getServerRhinoVersion()

Description copied from interface: RhinoConnection
