Name
DispatchHandler — dispatch to one of a list of handlers
Description
Dispatches to one of a list of handlers. When an exchange is handled,
each handler's condition is evaluated. If a condition
expression yields true, then the exchange is dispatched
to the associated handler with no further processing.
