## Package org.apache.commons.collections.buffer

This package contains implementations of the `Buffer` interface.

Description

Class Summary
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.

## Package org.apache.commons.collections.buffer Description

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
