Examples of org.drools.asm.MethodVisitor.visitJumpInsn()

org.drools.asm.MethodVisitor.visitJumpInsn()
Visits a jump instruction. A jump instruction is an instruction that may jump to another instruction. @param opcode the opcode of the type instruction to be visited. Thisopcode is either IFEQ, IFNE, IFLT, IFGE, IFGT, IFLE, IF_ICMPEQ, IF_ICMPNE, IF_ICMPLT, IF_ICMPGE, IF_ICMPGT, IF_ICMPLE, IF_ACMPEQ, IF_ACMPNE, GOTO, JSR, IFNULL or IFNONNULL. @param label the operand of the instruction to be visited. This operandis a label that designates the instruction to which the jump instruction may jump.

            mv.visitVarInsn( Opcodes.ALOAD,
                             1 );
            mv.visitTypeInsn( Opcodes.INSTANCEOF,
                              Type.getInternalName( clazz ) );
            final Label l4 = new Label();
            mv.visitJumpInsn( Opcodes.IFNE,
                              l4 );


            //       return false;
            mv.visitLabel( l3 );
            mv.visitInsn( Opcodes.ICONST_0 );
