Field Detail

node

protected DataManagerNode node

Aggregated node class instance

Constructor Detail

DataManagerNodeCtrl

public DataManagerNodeCtrl()

Default ctor initializes a new node instance. Do not use this to set up control for an existing node.

DataManagerNodeCtrl

public DataManagerNodeCtrl(DataManagerNode node)

Node constructor. Sets our node reference to the given node instance

DataManagerNodeCtrl

public DataManagerNodeCtrl(Controllable node)

Controllable constructor. Sets our node reference by casting the given Controllable reference to a DataManagerNode

Method Detail

getNode

public DataManagerNode getNode()

Initializing accessor for our local node instance. If no instance was defined on creation, then this method creates a new instance to return.

setNode

public void setNode(DataManagerNode node)

set the aggregated node instance. This should generally be done at construction time.

info

public void info(java.lang.String text)

Utility to log an informational message. This calls through to our node log method if we have a node reference, otherwise it just calls System.out.println with the given text. This method does not call getNode(), so it is safe to use it during ctor and initialization processing.

stateChanged

public void stateChanged(int prevState,
                         int currState)

React to a state change. The state change may have come from this bean, or it may have come from another control interface. The node has embedded state change logic which protects against invalid or redundent state transitions, so we don't need to worry about protecting the calls here.

There are more state changes in SAND then there are in the ServiceMBean, so we only pick up on some of the more major state changes here, like running or stopped. Here's how the other ServiceMBean state transitions are handled:

• create: a new MBean instance is created by the root node in the process of walking the NodeInstance[]s in the Configuration. This gets called once, regardless of what happens to the contained node.
• destroy: typically the container calls the service, and the service shuts down the node. Notifications aren't necessary.

Specified by:

stateChanged in interface ControlWrapper

paramChanged

public void paramChanged(java.lang.String paramName)

Our current MBean UIs are web browser pages that read the parameters each time the page is generated, so we don't currently react to parameter changes.

Specified by:

paramChanged in interface ControlWrapper

setControllable

public void setControllable(Controllable node)

Passthrough to setNode

Specified by:

setControllable in interface ControlWrapper

getControllable

public Controllable getControllable()

Wraps getNode

Specified by:

getControllable in interface ControlWrapper

sandInitialize

public void sandInitialize()
                    throws ControlWrapperException

Register and create this MBean

Specified by:

sandInitialize in interface ControlWrapper

Throws:

ControlWrapperException

startService

public void startService()
                  throws java.lang.Exception

Call the node startup processing when the service starts. This is public to allow for reflective access from an external control adaptor.

Throws:

java.lang.Exception

stopService

public void stopService()
                 throws java.lang.Exception

Call the node shutdown processing when the service stops. This is public to allow for reflective access from an external control adaptor.

Throws:

java.lang.Exception
