public class PredicatedBuffer extends PredicatedCollection implements Buffer
Bufferto validate that additions match a specified predicate.
This buffer exists to provide validation for the decorated buffer. It is normally created to decorate an empty buffer. If an object cannot be added to the buffer, an IllegalArgumentException is thrown.
One usage would be to ensure that no null entries are added to the buffer.
Buffer buffer = PredicatedBuffer.decorate(new UnboundedFifoBuffer(), NotNullPredicate.INSTANCE);
This class is Serializable from Commons Collections 3.1.
