public interface VariableManagerOwner

This interface is implemented by objects that manage Variables. Specifically, it has accessors, getVariableManager() and ensureVariableManager() through which this object's VariableValueManager can be retrieved.

For example, ViewObjectImpl implements this interface. To be precise, ComponentObjectImpl implements it and ViewObjectImpl inherits it.

Since:

JDeveloper 10.1.3

Method Summary

VariableValueManager	ensureVariableManager() Returns this object's Variable Value Manager.
java.lang.Class	getMessageBundleClass()
java.lang.String	getName() Returns the name of this Variable Manager Owner.
VariableValueManager	getVariableManager() Returns this object's current Variable Value Manager.
boolean	hasVariables() Returns a flag indicating whether this object has Variables or not.

Method Detail

getName

public java.lang.String getName()

Returns the name of this Variable Manager Owner.

Returns:

the name.

hasVariables

public boolean hasVariables()

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

Returns:

the flag indicating whether this object has Variables.

getVariableManager

public VariableValueManager getVariableManager()

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.

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

Returns:

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

ensureVariableManager

public VariableValueManager ensureVariableManager()

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

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()
