clever Context with generic type "auto-cast" feature
----------------------------------------------------
Key: CHAIN-56
URL: https://issues.apache.org/jira/browse/CHAIN-56
Project: Commons Chain
Issue Type: Improvement
Affects Versions: 2.0
Reporter: Simone Tripodi
Fix For: 2.0
Generics could help us on improving the Context class; since it is clear that
Context is a place where storing/retrieving objects identified by a key, I
propose adding two helper methods:
{code}
/** @since 2.0 */
<T> T retrieve( String key );
/** @since 2.0 */
<T> void store( String key, T object );
{code}
that would help users avoid the redundant code of type cast/checking when
assignments are already known (it throws a {{ClassCastException}} if types are
not assignable). At the same time, old pattern is supported, users can choose
their
preferred way to go, depending on their needs.
