Package org.apache.avalon.fortress.impl.handler Description

The handler package includes the lifestyle support systems.

Note that although these handlers make use of the avalon lifecycle interfaces, they are not 'real' components, and not every part of the lifecycle is supported. In particular, a handler doesn't start/stop or execute in any way.

The contents of this package are not a part of the fortress client API.
