DtVpfRow Class Reference

a class representing a row of data from a table. Rows don't really own any data, the columns own the data. The row only owns pointers to the data across the columns.

Member Function Documentation

DtVpfRow& DtVpfRow::operator=

(

const DtVpfRow &

row

)

Assignment operator is private to prevent copying.

virtual bool DtVpfRow::loadRow ( int  row )

virtual

loads this row with data from the columns at the given index

Returns

A boolean that represents the success or failure of the load

virtual const DtVpfTable* DtVpfRow::table ( ) const

virtual

returns the table that owns this row

Returns

A pointer to a DtVpfTable that owns this row

virtual const DtVpfData& DtVpfRow::operator[] ( const unsigned int  data ) const

virtual

allows indexed access to the elements of the row

Returns

A pointer to the data that is at the requested index

Exceptions

DtInvalidInput

if the index is out of range

virtual int DtVpfRow::size ( ) const

virtual

returns the number of elements in this row

Returns

An integer representing the number of elements in this row

virtual bool DtVpfRow::hasField ( const DtString &  field_name ) const

virtual

determines if the row has the named field

Returns

A boolean indicating whether or not the row has the requested field

virtual const DtVpfIntData* DtVpfRow::getIntField ( const DtString &  field ) const

virtual

Data specific type of data access.

Exceptions

DtInvalidInput

if the field is not the right type
