/**
    Used on an AMXProxy sub-interface only.  Indicates that the method
    is a proxy-based method for getting a child or List/Set/Map of children;
    <em>it doesn’t actually exist as an MBean attribute or method.  This annotation
    should not be applied when the method or Attribute actually does exist. This
    annotation is generally needed only when there are arbitrary types of children that
    are not known in advance and/or methods do not exist for them (eg because of derivation
    such as with config MBeans).
    <p>
    The proxy method to which the annotation is applied must be of one of the following forms,
    where the interface FooBar is a sub-interface of {@link org.glassfish.admin.amx.core.AMXProxy}.
    <code>
    <ul>
    <li>FooBar           getFooBar();        // gets a singleton child 
    <li>Set<FooBar>   getFooBar();        // gets all FooBar 
    <li>List<FooBar>  getFooBar();        // gets all FooBar 
    <li>Map<String,FooBar>  getFooBar();  // gets all FooBar 
    <li>FooBar[]         getFooBar();        // gets all FooBar 
    </ul>
    </code>
    The child type is derived from the method name, but if the standard derivation would result
    in the incorrect type then the annotation must include <code>type="child-type">, where
    "child-type" is the appropriate type.
