public interface VariableManagerOwner
extends VariableManagerOwnerBase

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.
ResourceBundleDef	getResourceBundleDef()
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

java.lang.String getName()

Returns the name of this Variable Manager Owner.

Returns:

the name.

hasVariables

boolean hasVariables()

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

Specified by:

hasVariables in interface VariableManagerOwnerBase

Returns:

the flag indicating whether this object has Variables.

getVariableManager

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).

Specified by:

getVariableManager in interface VariableManagerOwnerBase

Returns:

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

ensureVariableManager

VariableValueManager ensureVariableManager()

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 VariableManagerOwnerBase

Returns:

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

getMessageBundleClass

java.lang.Class getMessageBundleClass()

Specified by:

getMessageBundleClass in interface VariableManagerOwnerBase

getResourceBundleDef

ResourceBundleDef getResourceBundleDef()
