Method Detail

getSingleRecord

private static java.util.ArrayList<java.lang.String> getSingleRecord(java.util.List<java.util.List<java.lang.Object>> dataList,
                                                                     int position)

Gets the singles record in the arraylist of records ata certain position.

Parameters:

dataList - the list of records.

position - the position in which the record is to be gotten from.

Returns:

the single record.

checkContent

private static java.util.ArrayList<java.lang.Object> checkContent(java.util.ArrayList<java.lang.String> singleRecord)

Checks the content of the single record and assigns the datatype for each column.

Parameters:

singleRecord - the single record to be checked.

Returns:

the array of data type objects assigned to the single record.

checkLoop

private static void checkLoop(java.util.ArrayList<java.lang.Object> temp,
                              java.util.List<java.lang.Object> dataClass)
