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.

Method Summary

Modifier and Type	Method and Description
String	getFormalDescriptor() Returns the formal descriptor.
String	getMethodName() Returns the method name not including parameters.
Integer	getModifier() Returns the modifier used in the Java class file.
IMCType	getType() Returns the class this method is declared in.
Boolean	isNative() Whether this method is native.

Method Detail

getType

IMCType getType()

Returns the class this method is declared in.

Returns:

the class declaring this method
