Interface IMCMethod

All Known Implementing Classes:
MCMethod
public interface IMCMethod
A method representation.

There are many different ways methods are represented in Mission Control and in Java: MethodIdentfier, java.lang.String, stack trace locations, profiled methods, JFR methods etc.

Some IMCMethod implementations may support a wide range of method information while others might only be able provide the basic method name. It's up to the user of this interface to examine what is available. If information is missing null is returned.
