    • getResultType

      long getResultType()

      
      Get result type

      Returns:result type.See Also:EDMConstants.QueryOptions

    • getValue

      EDMSelect getValue()
                  throws EdmiException

      
      Get query result in case of single value - RESULT_AS_VALUE.

      Returns:query result as EDMSelect. If result type is not RESULT_AS_VALUE, an exception will be thrown.Throws:EdmiException - if the method fails.

      int noOfRows()
            throws EdmiException

      
      Get number of rows in the query matrix

      Returns:number of rows in the query matrixThrows:EdmiException - if the method fails

    • noOfColumns

      int noOfColumns()
               throws EdmiException

      
      Get number of columns in the query matrix

    • free

      void free()
         throws EdmiException

      
      Free the query , i.e. invalidate the query result and release the memory allocated by JNI.

      Throws:EdmiException - if the method fails

    • resultIsEmpty

      boolean resultIsEmpty()

      
      To check whether the query matched, i.e. whether the result is empty.

      Returns:true if the query result does not ciontain any data, true else

    • getRow

      EDMRow getRow(int row)
             throws EdmiException

      
      Get specific row from query result

                    boolean sdaiTyped)
             throws EdmiException

      
      Get specific row from query result

      Parameters:row - row number of cell (counting from 0)sdaiTyped - if True, EDMSelects will be filled with exact Sdai Type of value, otherwise just 5 basic types used - double,int,long,string,selectReturns:specified rowThrows:EdmiException - if the method fails
