Kind of:

	public void
testChildKeyMasksParentAdapterRegardlessOfType() {
		MutablePicoContainer parent = new
DefaultPicoContainer();
		MutablePicoContainer child = new
DefaultPicoContainer(parent);
		
		
		parent.addComponent("foo bar",239);
		parent.addComponent(515,515);
		// shall mask in parent
		child.addComponent("foo bar");
		
		// only 1 integer is resolvable here
		ByClass byClass = new ByClass(Integer.class);

		// shall retrieve all the integers from both
contaienrs
		assertEquals(1,byClass.lookup(child).size());
		
	
assertEquals(515,((ComponentAdapter)byClass.lookup(child).iterator().next()).getComponentKey());
	}


Here "foo bar" in child container ( which is string ) 
masks  integer keyed by "foo bar"
