Method Detail

getReference

                 T value)

Store a new inhabitant for the given descriptor.

Type Parameters:

T - inhabitant type.

value - inhabitant value.

Returns:

old inhabitant previously stored for the given descriptor or null if none stored.

remove

Remove a value for the descriptor if present in the scope instance store.

Parameters:

descriptor - key for the value to be removed.
