Class TWspHeaderSegmenter

class TWspHeaderSegmenter;

Description

TWspHeaderSegmenter segments a WSP buffer into WSP header/value pairs. It detects boundaries between header/values based on the WAP-WSP spec.

• To construct, buffer and string pool is passed in

• Call to TWspHeaderSegmenter::NextL(TWspField &) to iterate through the buffer - this returns a TWspField

• TWspHeaderSegmenter::NextL(TWspField &) returns KErrNotFound when done

Members

• Offset()constOffset returns the current offset into the buffer being parsed.
• TWspHeaderSegmenter(RStringPool,const TStringTable &,TPtrC8)Constructor

inline TWspHeaderSegmenter(RStringPool aPool, const TStringTable &aStringTable, TPtrC8 aBuffer);

Pre-Condition

The string table must be opened with the WSP Sting constants table

Description

Constructor

Parameters

RStringPool aPool In - an opened RStringPool - owned by the caller const TStringTable &aStringTable In - the string table in the string pool to use TPtrC8 aBuffer In - the buffer containing the WSP header data - owned by the caller

IMPORT_C TInt NextL(TWspField &aWspHeader);

Description

NextL iterates through the buffer. Each call returns a TWspField in the paramater.

Parameters

TWspField &aWspHeader Out - a TWspField containing the header <name,value> pair.

Return value

TInt KErrNone if next field is returned KErrNotFound at the end of the buffer - no TWspField param returned KErrCorrupt if segmenting does not parse correctly

Leave codes

RStringPool::OpenFStringL StringPool leave code if opening string fails.

inline TInt Offset() const;

Description

Offset returns the current offset into the buffer being parsed.

Return value

TInt TInt offset value. It will point to beginning of next segmented field. If NextL has not been called it will be set to 0. The beginning of the buffer. If buffer has been completely parsed, will return KErrNotFound.
