public java.lang.String getProxyClassName()

Gets the Proxy class name for the corresponding deployment platform.

Returns:

the String proxy class name

getApplicationModule

public ApplicationModule getApplicationModule()

isRegWithPiggyMan

public boolean isRegWithPiggyMan()

Is component registered with Piggy back Manager

Returns:

boolean

addListener

public void addListener(ComponentObjectListener listener)

Add a listener for the Component Object

Parameters:

listener - a listener for the component object

setName

protected void setName(java.lang.String name)

Name this object.

Overrides:

setName in class NamedObjectImpl

Parameters:

name - the name to be given to this object.

setParent

protected void setParent(NamedObjectImpl parent)

Sets this object's parent.

Parameters:

parent - the named object that is to be the parent of this object.

getVariableManager

public VariableValueManager getVariableManager()

Description copied from interface: VariableManagerOwner

Returns this object's current Variable Value Manager. It will return null if Variable Value Manager has been initialized.

When a framework object is first created, its Variable Value Manager may be null. This method does not initialize (create) the Variable Value Manager.

VariableManagerOwner.ensureVariableManager() in contrast, ensures that the Variable Value Manager is initialized (created).

Specified by:

getVariableManager in interface VariableManagerOwner

Returns:

this object's current Variable Value Manager. May return null if one was not yet initialized.

hasVariables

public boolean hasVariables()

Description copied from interface: VariableManagerOwner

Returns a flag indicating whether this object has Variables or not.

Specified by:

hasVariables in interface VariableManagerOwner

Returns:

the flag indicating whether this object has Variables.

ensureVariableManager

public VariableValueManager ensureVariableManager()

Description copied from interface: VariableManagerOwner

Returns this object's Variable Value Manager. If this object current has no Variable Value Manager, it will initialize (create) one.

Specified by:

ensureVariableManager in interface VariableManagerOwner

Returns:

this object's Variable Value Manager. Will create a Variable Value Manager if this object had no Variable Value Manager.

getMessageBundleClass

public java.lang.Class getMessageBundleClass()

Specified by:

getMessageBundleClass in interface VariableManagerOwner
