Class CDTDModel

class CDTDModel : public CBNFParser;

Description

Creates a tree that represents a specified DTD.

To use it:

1. call the base class function ProcessDataL() with the filename of the DTD, and call CommitL()

2. call GeneratedTree() to get the tree

Derivation

• MDataProviderObserver - MDataProviderObserver provides a virtual interface for any class to observe any MDataProvider, and provide data receiving services
• CBase - Base class for all classes to be instantiated on the heap

• CBNFParser - Base class for parsers that use a BNF tree to parse an input stream

• CDTDModel - Creates a tree that represents a specified DTD

static IMPORT_C CDTDModel *NewL(CAttributeLookupTable &aLUT);

Description

Allocates and constructs a new BNF parser.

Parameters

CAttributeLookupTable &aLUT Attribute lookup table in which to store attributes for the rule tree

Return value

CDTDModel * New parser

virtual IMPORT_C ~CDTDModel();

Description

protected: IMPORT_C CDTDModel(CAttributeLookupTable &aLUT);

Description

Parameters

CAttributeLookupTable &aLUT

virtual IMPORT_C void ResetL();

Description

Reset the parser to a state where it can accept and parse new input.

If no BNF tree yet exists the virtual method TreeL() is called to obtain the BNF tree for this parser. Any existing state of parsing and input data is destroyed.

IMPORT_C CBNFNode *GeneratedTree();

Description

Gets the root node of the tree generated to process the DTD.

It transfers ownership of the tree to the caller.

Return value

CBNFNode * Root node of the tree

IMPORT_C void BuildWml11DTDL(CBNFNode &aPackageRootNode);

Description

Builds a parser tree for the WML1.1 DTD.

Parameters

CBNFNode &aPackageRootNode A root node to which the generated tree is attached

protected: virtual IMPORT_C CBNFNode *TreeL();

Description

Creates a BNF rule tree to parse the input stream.

This overrides CBNFParser::TreeL().

Return value

CBNFNode * BNF rule tree

protected: virtual IMPORT_C void StartConditional(TParserNodeTypes aRuleType);

Description

Parameters

TParserNodeTypes aRuleType

protected: virtual IMPORT_C void EndConditional(TParserNodeTypes aRuleType, TBool aSuccess);

Description

Parameters

TParserNodeTypes aRuleType TBool aSuccess

class CDTDElementAttribute : public CBase;

Description

Represents an attribute of a DTD element.

Derivation

• CBase - Base class for all classes to be instantiated on the heap

• CDTDModel::CDTDElementAttribute - Represents an attribute of a DTD element

Members

Defined in CDTDModel::CDTDElementAttribute:

~CDTDElementAttribute()

inline virtual ~CDTDElementAttribute();

Description

Destructor.

Member enumerations

Enum KValueType

KValueType

Description
