TDbColSetIter(const CDbColSet &)

IMPORT_C

TDbColSetIter

(

const CDbColSet &

aColSet

)

Parameters

const CDbColSet & aColSet

Member Functions Documentation

Col()

TDbColNo

Col

(

)

const [inline]

Returns a column ordinal in the set for the currently referenced column definition.

operator TAny *()

operator TAny *

(

)

const [inline]

operator*()

const TDbCol &

operator*

(

)

const [inline]

Dereferences the iterator on the current column definition.

operator++()

IMPORT_C TDbColSetIter &

operator++

(

)

operator++(TInt)

TDbColSetIter

operator++

(

TInt

)

[inline]

Moves the iterator to the next column in the set post increment operator.

Note that this is implemented in terms of the pre-increment operator, and is less efficient.

Parameters

TInt

operator->()

const TDbCol *

operator->

(

)

const [inline]

Gets a member of the currently referenced column definition. This enables the use of the following constructs:

if (iter->iType==EDbColText && iter->iMaxLength<50)
