template<typename KEY, typename T>

template bool edm::detail::ThreadSafeRegistry< KEY, T >::getMapped	(	key_type const &	k,
		value_type &	result
	)		const

Retrieve the value_type object with the given key. If we return 'true', then 'result' carries the value_type object. If we return 'false, no matching key was found, and the value of 'result' is undefined.

const

Retrieve a pointer to the value_type object with the given key. If there is no object associated with the given key 0 is returned.

template<typename KEY, typename T>

template bool edm::detail::ThreadSafeRegistry< KEY, T >::insertMapped

(

value_type const &

v

)

Insert the given value_type object into the registry. If there was already a value_type object with the same key, we don't change it. This should be OK, since it should have the same contents if the key is the same. Return 'true' if we really added the new value_type object, and 'false' if the value_type object was already present.
