Examples of org.ow2.asm.MethodVisitor.visitJumpInsn()

org.ow2.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.
