Detailed Description

template<class ServiceType>
class My_registry_query_and_acquire< ServiceType >

A service acquiring registry query convenience class.

Uses the My_registry_query_string class to get a list of service names matching the pattern, acquires references for these and keeps them until the instance's destruction.

Typical use pattern is:

My_registry_query_and_acquire<SERVICE_TYPE(foo)> qry("foo", registry_ref);
if (qry->init()) error_out();
for (SERVICE_TYPE(foo) *x : qry) {
  x->method();
}
