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

com.alibaba.fastjson.asm.MethodVisitor.visitMethodInsn()
Visits a method instruction. A method instruction is an instruction that invokes a method. @param opcode the opcode of the type instruction to be visited. This opcode is either INVOKEVIRTUAL,INVOKESPECIAL, INVOKESTATIC, INVOKEINTERFACE or INVOKEDYNAMIC. @param owner the internal name of the method's owner class (see {@link Type#getInternalName() getInternalName}) or {@link com.alibaba.fastjson.asm.Opcodes#INVOKEDYNAMIC_OWNER}. @param name the method's name. @param desc the method's descriptor (see {@link Type Type}).
