Interface IMCFrame

All Known Implementing Classes:

AggregatableFrame, AggregatableFrame, MCFrame, StructTypes.JfrFrame

public interface IMCFrame

A stack trace frame.

It's recommended, but by design not a requirement, that classes that implements IMCFrame also implement IMCMethod. This allow classes in higher layers to treat a frame just like a method, for instance when using Eclipse object contribution mechanism.

This can be implemented simply by letting getMethod() return this.
