public class: BasicDependencyManager [javadoc | source]

All Implemented Interfaces:

DependencyManager is the record keeper of the dependencies in Geronimo. The DependencyManager does not enforce any dependencies, it is simply a place where components can register their intent to be dependent on another component. Since a JMX Component can pretty much do whatever it wants a component must watch the components it depends on to assure that they are following the J2EE-Management state machine.

The DependencyManager uses the nomenclature of parent-child where a child is dependent on a parent. The names parent and child have no other meaning are just a convience to make the code readable.
