Member Function Documentation

virtual bool DOMImplementation::hasFeature	(	const XMLCh *	feature,
		const XMLCh *	version
	)			const [pure virtual]

Test if the DOM implementation implements a specific feature.

Parameters:

	feature	The name of the feature to test (case-insensitive). The values used by DOM features are defined throughout the DOM Level 2 specifications and listed in the section. The name must be an XML name. To avoid possible conflicts, as a convention, names referring to features defined outside the DOM specification should be made unique.
	version	This is the version number of the feature to test. In Level 2, the string can be either "2.0" or "1.0". If the version is not specified, supporting any version of the feature causes the method to return true.

Returns:

true if the feature is implemented in the specified version, false otherwise.

Since:

DOM Level 1

virtual DOMDocumentType* DOMImplementation::createDocumentType	(	const XMLCh *	qualifiedName,
		const XMLCh *	publicId,
		const XMLCh *	systemId
	)			[pure virtual]

Creates an empty DOMDocumentType node.

Entity declarations and notations are not made available. Entity reference expansions and default attribute additions do not occur. It is expected that a future version of the DOM will provide a way for populating a DOMDocumentType.

Parameters:

	qualifiedName	The qualified name of the document type to be created.
	publicId	The external subset public identifier.
	systemId	The external subset system identifier.

Returns:

A new DOMDocumentType node with ownerDocument set to null.

Exceptions:

DOMException

INVALID_CHARACTER_ERR: Raised if the specified qualified name contains an illegal character. NAMESPACE_ERR: Raised if the qualifiedName is malformed. NOT_SUPPORTED_ERR: May be raised by DOM implementations which do not support the "XML" feature, if they choose not to support this method. Other features introduced in the future, by the DOM WG or in extensions defined by other groups, may also demand support for this method; please consult the definition of the feature to see if it requires this method.

Since:

DOM Level 2

virtual DOMDocument* DOMImplementation::createDocument	(	const XMLCh *	namespaceURI,
		const XMLCh *	qualifiedName,
		DOMDocumentType *	doctype,
		MemoryManager *const	manager = XMLPlatformUtils::fgMemoryManager
	)			[pure virtual]

Creates a DOMDocument object of the specified type with its document element.

Parameters:

	namespaceURI	The namespace URI of the document element to create.
	qualifiedName	The qualified name of the document element to be created.
	doctype	The type of document to be created or null. When doctype is not null, its ownerDocument attribute is set to the document being created.
	manager	Pointer to the memory manager to be used to allocate objects.

Returns:

A new DOMDocument object.

Exceptions:

DOMException

INVALID_CHARACTER_ERR: Raised if the specified qualified name contains an illegal character. NAMESPACE_ERR: Raised if the qualifiedName is malformed, if the qualifiedName has a prefix and the namespaceURI is null, or if the qualifiedName has a prefix that is "xml" and the namespaceURI is different from " http://www.w3.org/XML/1998/namespace" , or if the DOM implementation does not support the "XML" feature but a non-null namespace URI was provided, since namespaces were defined by XML. WRONG_DOCUMENT_ERR: Raised if doctype has already been used with a different document or was created from a different implementation. NOT_SUPPORTED_ERR: May be raised by DOM implementations which do not support the "XML" feature, if they choose not to support this method. Other features introduced in the future, by the DOM WG or in extensions defined by other groups, may also demand support for this method; please consult the definition of the feature to see if it requires this method.

Since:

DOM Level 2

virtual void* DOMImplementation::getFeature	(	const XMLCh *	feature,
		const XMLCh *	version
	)			const [pure virtual]

This method returns a specialized object which implements the specialized APIs of the specified feature and version, as specified in DOM Features.

This method also allow the implementation to provide specialized objects which do not support the DOMImplementation interface.

Parameters:

	feature	The name of the feature requested (case-insensitive). Note that any plus sign "+" prepended to the name of the feature will be ignored since it is not significant in the context of this method.
	version	This is the version number of the feature to test.

Returns:

Returns an object which implements the specialized APIs of the specified feature and version, if any, or null if there is no object which implements interfaces associated with that feature.

Since:

DOM Level 3

virtual DOMDocument* DOMImplementation::createDocument

(

MemoryManager *const

manager = XMLPlatformUtils::fgMemoryManager

)

[pure virtual]

Non-standard extension.

Create a completely empty document that has neither a root element or a doctype node.

static DOMImplementation* DOMImplementation::getImplementation

(

)

[static]

Non-standard extension.

Factory method for getting a DOMImplementation object. The DOM implementation retains ownership of the returned object. Application code should NOT delete it.

static bool DOMImplementation::loadDOMExceptionMsg	(	const short	msgToLoad,
		XMLCh *const	toFill,
		const XMLSize_t	maxChars
	)			[static]

Non-standard extension.

Load the default error text message for DOMException.

Parameters:

	msgToLoad	The DOM ExceptionCode id to be processed
	toFill	The buffer that will hold the output on return. The size of this buffer should at least be 'maxChars + 1'.
	maxChars	The maximum number of output characters that can be accepted. If the result will not fit, it is an error.

Returns:

true if the message is successfully loaded
