Example 20 with Label

use of jodd.asm5.Label in project intellij-community by JetBrains.

the class AdvancedEnhancer method emitCurrentCallback.

private static void emitCurrentCallback(CodeEmitter e, int index) {
    e.load_this();
    e.getfield(getCallbackField(index));
    e.dup();
    $Label end = e.make_label();
    e.ifnonnull(end);
    // stack height
    e.pop();
    e.load_this();
    e.invoke_static_this(BIND_CALLBACKS);
    e.load_this();
    e.getfield(getCallbackField(index));
    e.mark(end);
