com.sun.star.lib.uno.helper
Class WeakBase

java.lang.Object
  com.sun.star.lib.uno.helper.WeakBase

All Implemented Interfaces:: XTypeProvider, XInterface, XWeak

Direct Known Subclasses:: ComponentBase

public class WeakBase
extends Object
implements XWeak, XTypeProvider
extends Object
implements XWeak, XTypeProvider

This class can be used as the base class for UNO components. It implements the capability to be kept weak (com.sun.star.uno.XWeak) and it implements com.sun.star.lang.XTypeProvider which is necessary for using the component with StarBasic.

Method Detail

queryAdapter

public XAdapter queryAdapter()

Method of XWeak. The returned XAdapter implementation can be used to keap a weak reference to this object.

Specified by:: queryAdapter in interface XWeak

Returns:: a com.sun.star.uno.XAdapter implementation.

finalize

protected void finalize()
                 throws Throwable

Override of Object.finalize. When there are no references to this object anymore then the garbage collector calls this method. Thereby causing the adapter object to be notified. The adapter, in turn, notifies all listeners (com.sun.star.uno.XReference)

Overrides:: finalize in class Object

Throws:: Throwable

getTypes

public Type[] getTypes()

Method of XTypeProvider. It returns an array of Type objects which represent all implemented UNO interfaces of this object.

Specified by:: getTypes in interface XTypeProvider

Returns:: Type objects of all implemented interfaces.

getImplementationId

public byte[] getImplementationId()

Method of XTypeProvider. It provides an identifier that represents the set of UNO interfaces implemented by this class. All instances of this class which run in the same Java Virtual Machine return the same array. (This only works as long the ClassLoader preserves the class even if no instance exist.)

Specified by:: getImplementationId in interface XTypeProvider

Returns:: identifier as array of bytes
