Package org.apache.commons.collections.buffer

This package contains implementations of the Buffer interface.

The following implementations are provided in the package:

• PriorityBuffer - provides for removal based on a comparator ordering
• BoundedFifoBuffer - implements a buffer with a fixed size that throws exceptions when full
• CircularFifoBuffer - implements a buffer with a fixed size that discards oldest when full
• UnboundedFifoBuffer - implements a buffer that grows in size if necessary

The following decorators are provided in the package:

• Synchronized - synchronizes method access for multi-threaded environments
• Unmodifiable - ensures the collection cannot be altered
• Predicated - ensures that only elements that are valid according to a predicate can be added
• Typed - ensures that only elements that are of a specific type can be added
• Transformed - transforms elements added to the buffer
• Blocking - blocks on get and remove until an element is available

Class Summary

Class	Description
AbstractBufferDecorator	Decorates another Buffer to provide additional behaviour.
BlockingBuffer	Decorates another Buffer to make BlockingBuffer.get() and BlockingBuffer.remove() block when the Buffer is empty.
BoundedBuffer	Decorates another Buffer to ensure a fixed maximum size.
BoundedFifoBuffer	The BoundedFifoBuffer is a very efficient implementation of Buffer that is of a fixed size.
CircularFifoBuffer	CircularFifoBuffer is a first in first out buffer with a fixed size that replaces its oldest element if full.
PredicatedBuffer	Decorates another Buffer to validate that additions match a specified predicate.
PriorityBuffer	Binary heap implementation of Buffer that provides for removal based on Comparator ordering.
SynchronizedBuffer	Decorates another Buffer to synchronize its behaviour for a multi-threaded environment.
TransformedBuffer	Decorates another Buffer to transform objects that are added.
TypedBuffer	Decorates another Buffer to validate that elements added are of a specific type.
UnboundedFifoBuffer	UnboundedFifoBuffer is a very efficient implementation of Buffer that can grow to any size.
UnmodifiableBuffer	Decorates another Buffer to ensure it can't be altered.
