WeakBase (Java UNO Runtime Reference)

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
```
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.

public WeakBase()
```
- Method Detail
  - queryAdapter
```
public XAdapter queryAdapter()
```
    Method of XWeak. The returned XAdapter implementation can be used to keep 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()
```
    Obsolete method of XTypeProvider.
    
    Specified by:
    
    getImplementationId in interface XTypeProvider
