TSqlBufWIterator Class Reference

class TSqlBufWIterator

TSqlBufWIterator iterator gives write-only access to the flat buffer content (RSqlBufFlat class). For convenience, with TSqlBufWIterator flat buffer fields can be set as: TInt, TInt64, TReal, 16-bit text, 8-bit binary block.

MoveTo(TInt)

void

MoveTo

(

TInt

aIndex

)

[inline]

Moves to the specified field in the flat buffer.

Parameters

TInt aIndex

Field index

Next()

TBool

(

)

[inline]

Moves to the next flat buffer field

Set(RSqlBufFlat &)

void

Set

(

RSqlBufFlat &

aBuf

)

[inline]

Initializes the iterator. After the initialization the iterator points to the first flat buffer field - 1.

Parameters

RSqlBufFlat & aBuf

A reference to the buffer which will be iterated.

SetAsNotPresent(TInt, TInt)

void	SetAsNotPresent	(	TInt	aType,
			TInt	aLength
		)	[inline]

Sets the current flat buffer field as "Not present".

Parameters

TInt aType	Field type. One of TSqlColumnType enum item values or ESqlText8.
TInt aLength	Field length in bytes

SetBinary(const TDesC8 &)

TInt

SetBinary

(

const TDesC8 &

aValue

)

[inline]

Initializes current flat buffer field with a block of binary data.

Parameters

const TDesC8 & aValue

An 8 bit descriptor pointing to the block of data to be set as a field content.

SetInt(TInt)

TInt

SetInt

(

TInt

aValue

)

[inline]

Initializes current flat buffer field with an integer value.

Parameters

TInt aValue

An integer value to be set as a field content

SetInt64(TInt64)

TInt

SetInt64

(

TInt64

aValue

)

[inline]

Initializes current flat buffer field with an 64 bit integer value.

Parameters

TInt64 aValue

A 64 bit integer value to be set as a field content

SetNull()

void

SetNull

(

)

[inline]

Sets the current flat buffer field to NULL.

SetReal(TReal)

TInt

SetReal

(

TReal

aValue

)

[inline]

Initializes current flat buffer field with a real value.

Parameters

TReal aValue

A real value to be set as a field content

SetText(const TDesC16 &)

TInt

SetText

(

const TDesC16 &

aValue

)

[inline]

Initializes current flat buffer field with a block of 16 bit text.

Parameters

const TDesC16 & aValue

A 16 bit descriptor pointing to the block of text to be set as a field content.

SetZeroBlob(TInt)

TInt

SetZeroBlob

(

TInt

aSize

)

[inline]

Initializes current flat buffer field with a zeroblob of the specified size.

Parameters

TInt aSize

The size, in bytes, of the zeroblob to be set as the field content.
