public class StubCode
extends TreeCode

StubCode is used to generate non-canonical tree code stubs for native methods. That is, a StubCode is a thunk from runtime-native methods to the JNI interface which C-code "native methods" conform to.

StubCode will generate a thunk for any old method you give to its constructor. It is the job of the nativeTreeCodeFactory() in Runtime1.Runtime to weed out native from non-native methods, give the proper ones to StubCode, and do the right thing with the stubs that StubCode makes.
