T
- The type parameter corresponding to the type parameter of the
Class
used as key (getKey()
).public class AdapterKey<T>
extends java.lang.Object
Class
key and String
role to register adapters at
and retrieve them from IAdaptable
s. Using an AdapterKey
instead of just a Class
or TypeToken
key allows to register
several adapters under the same key, serving different roles. Nevertheless,
adapters can still be accessed in a type-safe manner. To register a default
adapter for a certain Class
or TypeToken
key, the
DEFAULT_ROLE
may be used.
Creating AdapterKey
s is supported by get(Class, String)
and
get(TypeToken, String)
, as well as get(Class)
and
get(TypeToken)
respectively, where the latter two will use the
DEFAULT_ROLE
.
