CAttributeLookupTable Class Reference

class CAttributeLookupTable : public CBase

Provides an attribute lookup table, which maintains a global set of unique IDs to be defined for document node attributes and language tags.

It does this by generating a unique (in the scope of the lookup table object) ID for any string passed to it. Once a string has been seen once, any further references to it will map back to the same ID value.

Des2IDL(const TDesC &)

IMPORT_C const HBufC * Des2IDL ( const TDesC & )

Gets a unique ID for a specified descriptor.

If this is the first time the descriptor has been used, a new ID will be allocated.

Parameters

const TDesC & Descriptor to get ID for

FindDes(const TDesC &)

CAttributeLookupTableNode * FindDes ( const TDesC & ) [private]

Parameters

const TDesC &

Hash(const TDesC &)

TUint Hash ( const TDesC & ) [private]

Parameters

const TDesC &

KeyExists(const TDesC &)

IMPORT_C const HBufC * KeyExists ( const TDesC & )

Tests if an ID has been allocated for a specified descriptor.

Parameters

const TDesC & Descriptor to test

NewL()

IMPORT_C CAttributeLookupTable * NewL ( ) [static]

Allocates and constructs a new attribute lookup table.

Reset()

IMPORT_C void Reset ( )

Clears all allocated IDs.
