Class MethodMap

java.lang.Object
  harpoon.Backend.Maps.MethodMap

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

ClassMethodMap, InterfaceMethodMap

public abstract class MethodMap
extends Object
implements Serializable

A MethodMap assigns an ordering to the methods in a class. Typically a separate MethodMap will be used for class and interface methods. Note that a MethodMap does not specify a direct offset, since the size of each method pointer will be machine-dependent and the start of the method table may be offset from the class descriptor pointer. The function of an OffsetMap is to take the orderings specified by a pair of MethodMaps (one for single-inheritance classes, one for interfaces) and layout a class descriptor table from it, computing appropriate byte offsets to the various method pointers.
