oracle.dss.dataView.ComponentHandle
public abstract class ComponentHandle
Represents a component in a Dataview
. A ComponentHandle
provides access to the component that it represents. It also provides information about the component, through the ComponentInfo
object. Concrete subclasses of this class provide information that is specific to the kind of component they describe.
ComponentHandle
classes are used by Dataview
objects to pass access and information to other classes. For example, when you listen for a SelectEvent
, you can access the selected component by getting the ComponentHandle
object from the event.

ComponentInfo
for the component that this ComponentHandle
represents. Concrete subclasses return appropriate subclasses of the ComponentInfo
class. For example, a DataComponentHandle
returns a DataComponentInfo
object, which provides the row and column of the component.ComponentHandle
represents. Returns null
if there is no ComponentInfo
or if the ComponentInfo
is null
