Luca Burgazzoli updated CAMEL-13948:
------------------------------------
Description:
The camel registry support binding multiple classes to the same entry via the
bind method:
{code:java}
void bind(String id, Class<?> type, Object bean)
{code}
The underlying implementation is roughly:
{code:java}
void bind(String id, Class<?> type, Object bean) {
computeIfAbsent(id, k -> new LinkedHashMap<>()).put(type, bean);
}
{code}
So assuming I have a class MyLogComponent which extends LogComponent and I do
the following binding:
{code:java}
Component a = new LogComponent()
Component b = new MyLogComponent()
registry.bind("log", LogComponent.class, a )
registry.bind("log", MyLogComponent.class, b)
{code}
then lookupByNameAndType may return different values depending on the type used
for looking up the beans:
{code:java}
registry.lookupByNameAndType("log", LogComponent.class) ==> a
registry.lookupByNameAndType("log", MyLogComponent.class) ==> b
registry.lookupByNameAndType("log", DefaultComponent.class) ==> a or b
(depends on the order)
{code}
