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
