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

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()
```

Whether or not this connection is connected.

Specified by:

getConnectedState in interface RhinoConnection

Returns:

state of the connection

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

The version of Rhino this connection is to. Only available for Rhino versions 2.2 and above. This method returns null for versions of Rhino prior to 2.2.

Specified by:

getServerRhinoVersion in interface RhinoConnection

Returns:

Rhino version

setAllowedExecutionContext
```
public void setAllowedExecutionContext(ExecutionContext ctx)
```
Description copied from interface: RhinoConnection

Tell this connection to only allow particular connection contexts. See ExecutionContext for more details.

Specified by:

setAllowedExecutionContext in interface RhinoConnection

Parameters:

ctx - the context to allow
