template<typename caller_type >

string registry::get_service_by_type	(	caller_type &	caller,
		string	service_type
	)

Synchronously looks up a service by its service type.

Parameters:

caller	The Caller to use to perform the lookup.
service_type	A string identifying the service type to look up.

Returns:

The private group name of the first service found matching the specified type. If no service is found, returns an empty string.

string registry::service_group_registry

(

)

[inline]

Returns a string identifying the group to which all Registry instances belong.

This is the group where clients should direct their queries.

Returns:

A string identifying the group to which all Registry instances belong.
