                         LookupChangeListener<? super T> lookupChangeListener)

Binds the given lookup change listener that is wrapped within a WeakLookupChangeListener. Adds the given listener and calls LookupChangeListener#lookupChanged(LookupChangeEvent) for the first time.

Type Parameters:

T - a T object.

Parameters:

lookupChangeListener - the listener that is added

type - a Class object.

bindWeak

public <T> void bindWeak(@Nonnull
                         TypedLookupChangeListener<T> lookupChangeListener)

Binds the given lookup change listener (that is wrapped within a WeakLookupChangeListener) with the key retrieved from TypedLookupChangeListener#getType(). Adds the given listener and calls LookupChangeListener#lookupChanged(LookupChangeEvent) for the first time.

Type Parameters:

T - a T object.

Parameters:

lookupChangeListener - the listener that is added
