WSCindexVariantData

Form WSCindexVariantData() Function Constructor of an indexed variant type data list structure Create an instance of an indexed variant type data list Description Parameters None. Return value A pointer to an instance of an indexed variant type data list Notice Samples WSCindexVariantData indexdata; long data1 = 100; char* str1 = "data"; //Memorize values by attaching the index indexdata["data1"] = data1; indexdata["data2"] = str1; //When you want to do the same using setData() indexdata.setData("data1",data1); indexdata.setData("data2",str1); //Obtain memorized data by specifying the index long val1 = indexdata["data1"]; WSCstring val2 = indexdata["data2"]; //When you want to do the same using getData() long val3 = indexdata.getData("data1"); WSCstring val4 = indexdata.getData("data2"); //Obtaining the index: char* index1 = indexdata.getIndex(0); //"data1" is returned char* index2 = indexdata.getIndex(1); //"data2" is returned //Obtaining a value by a position long val5 = indexdata.getData(0); WSCstring val6 = indexdata.getData(1); //Obtaining the number of data: long num = indexdata.getNum(); //Deleting data by specifying the index indexdata.del("data2"); //Deleting data by specifying a position indexdata.delPos(0); //Clearing all data at once indexdata.clear();

Form WSCindexVariantData(WSCindexVariantData&) Function Copy constructor of an indexed variant type data Duplicate the given list Description Parameters None. Return value A pointer to an instance of indexed variant type data list Notice Samples //Memorize values attaching the index WSCindexVariantData indexdata; indexdata["data1"] = (void*)data1; indexdata["data2"] = (void*)data2; //Copy another indexdata2 by a copy constructor WSCindexVariantData indexdata2(indexdata);

Form long setData(char* index,WSCvariant data) Function Store variant type data specifying the index Various type data can be specified because it is variant type. Description Parameters (in)char* index Index name (in)WSCvariant data Daata Return value WS_NO_ERR= Normal, otherwise error Notice Samples Refer to WSCindexVariantData()

Form char* getIndex(long pos) Function Obtain a specified position index Description Parameters (in)long pos Data position (Top is 0) Return value Index name Notice Samples Refer to WSCindexVariantData()

Form WSCvariant &getData(char* index) Function Obtain data corresponding to a specified index Description Parameters (in)char* index Index Return value Stored data Notice When there is no data corresponding to the index, it returns 0 Samples Refer to WSCindexVariantData()

Form WSCvariant &getData(long pos) Function Obtain data of a specified position Description Parameters (in)long pos Data position (Top is 0) Return value Data Notice Samples Refer to WSCindexVariantData()

Form long getNum() Function Obtain the number of data that have list Description Parameters None. Return value The number of data Notice Samples Refer to WSCindexVariantData()

Form long del(char* index); Function Delete data corresponding to a specified index Description Parameters (in)char* index Index Return value WS_NO_ERR= Normal, otherwise error Notice Samples Refeer to WSCindexVariantData()

Form long delPos(long pos); Function Delete data of a specified position Description Parameters (in)long pos Data position (Top is 0) Return value WS_NO_ERR= Normal, otherwise error Notice Samples Refer to WSCindexVariantData()

Form void clear(); Function Delete all retained data Description Parameters None. Return value None. Notice Samples Refer to WSCindexVariantData()

Form WSCvariant& operator [] (char* index) Function Obtain data corresponding to a specified index Description Parameters (in)char* index Index Used as follows Return value Data Notice Samples Refer to WSCindexVariantData()

Form WSCindexVariantData& operator = (WSCindexVariantData& src) Function Copy operator Description Parameters (in)WSCindexVariant& src Copy source instance Return value Copied instance Notice Samples //Memorize values attached to the index WSCindexData indexdata; indexdata["data1"] = (void*)data1; indexdata["data2"] = (void*)data2; //Copy another indexdata2 by a copy constructor WSCindexData indexdata2; //Execute copy operator indexdata2 = indexdata;
