Re: invokeexpr's

[Ondrej LHOTAK <olhotak@sable.mcgill.ca>]

InvokeExpr's are split into two types: StaticInvokeExpr and
InstanceInvokeExpr. A StaticInvokeExpr is used to call a static method,
so it does not use a receiver object. InstanceInvokeExpr is used to call
non-static methods.

InstanceInvokeExpr are further subdivided into InterfaceInvokeExpr,
VirtualInvokeExpr, and SpecialInvokeExpr. These correspond to the
three bytecodes invokeinterface, invokevirtual, and invokespecial,
respectively. The first is used to call a method declared in an
interface, the second a method declared in a class, and the third to
call a constructor.

Hope that helps.
