This artifact provides a single jar that contains all classes required to use remote EJB and JMS, including
all dependencies. It is intended for use by those not using maven, maven users should just import the EJB and
JMS BOM's instead (shaded JAR's cause lots of problems with maven, as it is very easy to inadvertently end up
with different versions on classes on the class path).
This package contains implementations of the
{@link org.apache.commons.collections.Bag Bag} and
{@link org.apache.commons.collections.SortedBag SortedBag} interfaces.
A bag stores an object and a count of the number of occurences of the object.
The following implementations are provided in the package:
- HashBag - implementation that uses a HashMap to store the data
- TreeBag - implementation that uses a TreeMap to store the data
The following decorators are provided in the package:
- Synchronized - synchronizes method access for multi-threaded environments
- Unmodifiable - ensures the bag 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 each element added to the bag
