Examples of com.alibaba.fastjson.asm.MethodVisitor.visitTypeInsn()

com.alibaba.fastjson.asm.MethodVisitor.visitTypeInsn()
Visits a type instruction. A type instruction is an instruction that takes the internal name of a class as parameter. @param opcode the opcode of the type instruction to be visited. This opcode is either NEW, ANEWARRAY, CHECKCASTor INSTANCEOF. @param type the operand of the instruction to be visited. This operand must be the internal name of an object orarray class (see {@link Type#getInternalName() getInternalName}).
