@Deprecated(since="2021-04-30") public abstract class AbstractCollectionDecorator extends java.lang.Object implements java.util.Collection
Deprecated.Commons Collections 3 is in maintenance mode. Commons Collections 4 should be used instead.Decorates anotherCollection
to provide additional behaviour.Each method call made on this
Collection
is forwarded to the decoratedCollection
. This class is used as a framework on which to build to extensions such as synchronized and unmodifiable behaviour. The main advantage of decoration is that one decorator can wrap any implementation ofCollection
, whereas sub-classing requires a new class to be written for each implementation.This implementation does not perform any special processing with
iterator()
. Instead it simply returns the value from the wrapped collection. This may be undesirable, for example if you are trying to write an unmodifiable implementation it might provide a loophole.- Since:
- Commons Collections 3.0
