Class ProfileData

java.lang.Object
org.jruby.runtime.profile.builtin.ProfileData
All Implemented Interfaces:
ProfileCollection
public class ProfileData extends Object implements ProfileCollection
Encapsulates the logic of recording and reporting profiled timings of method invocations. This keeps track of aggregate values for callers and callees of each method.
