; Author: Jonathan Meyer, 10 July 1996
; Purpose: Example of using invokeinterface
; -------------------------------------------------------------------------
;
; Demonstrates invoking an interface method
;
.class public examples/InvokeInterface
.super java/lang/Object
; standard initializer
.method public <init>()V
aload_0
invokenonvirtual java/lang/Object/<init>()V
return
.end method
;
; This is a rather silly example - since the result of calling the
; interface method isn't actually used. But it does illustrate how to
; use invokeinterface.
;
.method public example(Ljava/util/Enumeration;)V
.limit stack 1
.limit locals 3
; push local variable 1 (the Enumeration object)
aload_1
; now call the hasMoreElements() interface method.
invokeinterface java/util/Enumeration/hasMoreElements()Z 1
; store the integer result in local variable 2
istore_2
; done
return
.end method
.method public static main([Ljava/lang/String;)V
return
.end method
