Method ServiceMethod

contrib/fb303/cpp/ServiceTracker.cpp:428–443

* Creates a ServiceMethod, used for tracking a single service method * invocation (via the ServiceTracker). The passed name of the * ServiceMethod is used to group statistics (e.g. counts and durations) * for similar invocations; the passed signature is used to uniquely * identify the particular invocation in the log. * * note: A version of this constructor is provided that automatically *

 *                                invocation (usually name plus parameters).
