org.rioproject.impl.watch.WatchInjector

The WatchInjector provides support for declarative Watch management, by taking a {@link org.rioproject.watch.WatchDescriptor} and creating{@link SamplingWatch} instances which are then registered foran instantiated service.

If the watch already exists in the bean's {@link WatchRegistry}, the watch will not be added.

The bean must declare a Java bean getter method that has as it's return type one of the following:

Supported primitive types: int.class, long.class, float.class, double.class
Supported types: Integer.class, Long.class, Lloat.class, Double.class

The read property return type is verified prior to watch creation. For example, given a bean called Foo, which declares a method called getCount() :

 public class Foo  { ... public long getCount() { return(value); } ... }

Finally, in the OperationalString, Watch declaration is accomplished using the embedded the <Monitor> element, for example:

 <SLA ID="backlog" Low="100" High="500"> <PolicyHandler type="scaling" max="10" lowerDampener="3000" upperDampener="3000"/> <Monitor name="entryCounter" property="count" period="10000"/> </SLA>

This declaration creates a {@link SamplingWatch} with a nameof entryCounter, which adds the value returned from the getCount() method every 10 seconds. @author Dennis Reedy
