 Method redirectors can use the following [[https://github.com/SpongePowered/Mixin/wiki/Injection-Point-Reference|injection point references]]:

 The ''INVOKE'' injection point reference is used for invocations of ''target'' in ''method'', which means that it can be used in order to redirect a method immediately before it is called.

 Instance method redirectors are similar to static methood redirectors, but they should have an additional parameter at the start of their parameter lists for the objects on which their ''target''s are invoked.
