/**
* Delete command annotation
*
* A method annotated with the Delete annotation will generate a generic
* implementation of a delete administrative command responsible for
* delete instances of the type as referenced by the annotated method.
*
* The deleted type is determine by the annotated method which must
* follow one of the two following patterns :
* List<X> getXs();
* or
* void setX(X x);
*
* X is the type of instance that will be deleted, the name of the
* method is actually immaterial. So for example, the following
* <pre>
*
* will all be valid annotated methods.
*
* The instance to be removed from the parent must be resolved by the
* resolver attribute. The resolver can use injection or the command
* invocation parameters (using the {@link org.glassfish.api.Param}
* annotation) to get enough information to look up or retrieve the
* instance to be deleted.
*
* Usually, most instances can be looked up by using the instance type
* and its key (provided by the --name or --target parameters for instance).
*
* See {@link Create} for initialization information
