org.apache.avalon.framework.component.ComponentSelector
A ComponentSelector selects Components based on a hint. The contract is that all the Components implement the same role.
A role is better understood by the analogy of a play. There are many different roles in a script. Any actor or actress can play any given part and you get the same results (phrases said, movements made, etc.). The exact nuances of the performance is different.

Below is a list of things that might be considered the same role:
- XMLInputAdapter and PropertyInputAdapter
- FileGenerator and SQLGenerator
The ComponentSelector does not specify the methodology of getting the Component, merely the interface used to get it. Therefore the ComponentSelector can be implemented with a factory pattern, an object pool, or a simple Hashtable.

Deprecated: Use {@link org.apache.avalon.framework.service.ServiceSelector} instead.
