Refactoring

[RobertObkircher]

• use anonymous namespaces instead of "static"
• create folders like "class" and "interpeter" and "jvm/jni"
• "namespace class" won't work, so we need a better name
• should namespaces be indented or not?

namespace {
int x;
}
namespace {
   int x;
}

• Move ClassFile into it's own file and add more useful helper functions
• rename ClassFile to Class? or maybe split it into Class (with members: header, padding, ClassFile)
• Should we just use the jni types? I would get rid of Reference and replace it by pointers to Object.
• Make more things private / improve encapsulation
• Try to teach the debugger how to display constant pool entries (or store the classname directly in the ClassFile to make it easier to see)
• Remove unnecessary usage of the "inline" keyword

I like Reference

• move the various utility functions in interpreter.cpp into a separate file

[RobertObkircher]

• eliminate "this_class" and replace it with a string for the name
• CONSTANT_Class_info* could just store the ClassFile * instead. For that the parser would have to know the address of the result (which it does, but it would have to be documented, so that the caller doesn't copy the result).

[RobertObkircher]

• store sizeof(type) in the (primitive) class to make array operations simpler?

[RobertObkircher]

• create helper functions for pushing/popping frames

[mischnic]

• allocate_array doesn't have to be generic anymore, use clazz->offset_of_array_after_header and clazz->element_size instead.
