An adapter 'matching' the AdapterKey
is an adapter, which is
registered with an AdapterKey
, whose TypeToken
key (
AdapterKey.getKey()
) refers to the same type or a sub-type of the
given AdapterKey
's TypeToken
key (@see
TypeToken.isAssignableFrom(TypeToken)
and whose role (
AdapterKey.getRole()
)) equals the role of the given
AdapterKey
's role.
If there is more than one adapter that 'matches' the given
AdapterKey
, or there is no one 'matching' it, null
will be returned.
