Since:: DOM Level 3

virtual void xercesc::DOMBuilder::setErrorHandler ( DOMErrorHandler *const handler ) [pure virtual]

Set the error handler.

This method allows applications to install their own error handler to trap error and warning messages.

Any previously set handler is merely dropped, since the parser does not own them.

"Experimental - subject to change"

Parameters:

handler

A const pointer to the user supplied error handler.

See also:: getErrorHandler

Since:: DOM Level 3

virtual void xercesc::DOMBuilder::setEntityResolver ( DOMEntityResolver *const handler ) [pure virtual]

Set the entity resolver.

This method allows applications to install their own entity resolver. By installing an entity resolver, the applications can trap and potentially redirect references to external entities.

Any previously set resolver is merely dropped, since the parser does not own them.

"Experimental - subject to change"

Parameters:

handler

A const pointer to the user supplied entity resolver.

See also:: getEntityResolver

Since:: DOM Level 3

virtual void xercesc::DOMBuilder::setFilter ( DOMBuilderFilter *const filter ) [pure virtual]

Set the application filter.

When the application provides a filter, the parser will call out to the filter at the completion of the construction of each Element node. The filter implementation can choose to remove the element from the document being constructed (unless the element is the document element) or to terminate the parse early. If the document is being validated when it's loaded the validation happens before the filter is called.

Any previously set filter is merely dropped, since the parser does not own them.

"Experimental - subject to change"

Parameters:

filter

A const pointer to the user supplied application filter.

See also:: getFilter

Since:: DOM Level 3

virtual void xercesc::DOMBuilder::setFeature	(	const XMLCh *const	name,
		const bool	state
	)			`[pure virtual]`

It is possible for a DOMBuilder to recognize a feature name but to be unable to set its value.

"Experimental - subject to change"

See http://xml.apache.org/xerces-c/program-dom.html#DOMBuilderFeatures for the list of supported features.

Parameters:

	name	The feature name.
	state	The requested state of the feature (true or false).

Exceptions:

DOMException

NOT_SUPPORTED_ERR: Raised when the DOMBuilder recognizes the feature name but cannot set the requested value.
NOT_FOUND_ERR: Raised when the DOMBuilder does not recognize the feature name.

Since:: DOM Level 3

virtual DOMDocument* xercesc::DOMBuilder::parse ( const DOMInputSource & source ) [pure virtual]

Parse via an input source object.

This method invokes the parsing process on the XML file specified by the DOMInputSource parameter. This API is borrowed from the SAX Parser interface.

The parser owns the returned DOMDocument. It will be deleted when the parser is released.

"Experimental - subject to change"

Parameters:

source

A const reference to the DOMInputSource object which points to the XML file to be parsed.

Returns:: If the DOMBuilder is a synchronous DOMBuilder the newly created and populated DOMDocument is returned. If the DOMBuilder is asynchronous then null is returned since the document object is not yet parsed when this method returns.

Exceptions:

	SAXException	Any SAX exception, possibly wrapping another exception.
	XMLException	An exception from the parser or client handler code.
	DOMException	A DOM exception as per DOM spec.

virtual DOMDocument* xercesc::DOMBuilder::parseURI ( const XMLCh *const systemId ) [pure virtual]

Parse via a file path or URL.

This method invokes the parsing process on the XML file specified by the Unicode string parameter 'systemId'.

The parser owns the returned DOMDocument. It will be deleted when the parser is released.

"Experimental - subject to change"

Parameters:

systemId

A const XMLCh pointer to the Unicode string which contains the path to the XML file to be parsed.

Returns:: If the DOMBuilder is a synchronous DOMBuilder the newly created and populated DOMDocument is returned. If the DOMBuilder is asynchronous then null is returned since the document object is not yet parsed when this method returns.

Exceptions:

The parser owns the returned DOMDocument. It will be deleted when the parser is released.

"Experimental - subject to change"

Parameters:

systemId

A const char pointer to a native string which contains the path to the XML file to be parsed.

Returns:: If the DOMBuilder is a synchronous DOMBuilder the newly created and populated DOMDocument is returned. If the DOMBuilder is asynchronous then null is returned since the document object is not yet parsed when this method returns.

virtual void xercesc::DOMBuilder::parseWithContext	(	const DOMInputSource &	source,
		DOMNode *const	contextNode,
		const short	action
	)			`[pure virtual]`

Parse via an input source object.

This method invokes the parsing process on the XML file specified by the DOMInputSource parameter, and inserts the content into an existing document at the position specified with the contextNode and action arguments. When parsing the input stream the context node is used for resolving unbound namespace prefixes.

"Experimental - subject to change"

Parameters:

	source	A const reference to the DOMInputSource object which points to the XML file to be parsed.
	contextNode	The node that is used as the context for the data that is being parsed. This node must be a Document node, a DocumentFragment node, or a node of a type that is allowed as a child of an element, e.g. it can not be an attribute node.
	action	This parameter describes which action should be taken between the new set of node being inserted and the existing children of the context node.

Exceptions:

DOMException

NOT_SUPPORTED_ERR: Raised when the DOMBuilder doesn't support this method.
NO_MODIFICATION_ALLOWED_ERR: Raised if the context node is readonly.

Since:: DOM Level 3

virtual void* xercesc::DOMBuilder::getProperty ( const XMLCh *const name ) const [pure virtual]

Query the current value of a property in a DOMBuilder.

The builder owns the returned pointer. The memory allocated for the returned pointer will be destroyed when the builder is deleted.

To ensure assessiblity of the returned information after the builder is deleted, callers need to copy and store the returned information somewhere else; otherwise you may get unexpected result. Since the returned pointer is a generic void pointer, see http://xml.apache.org/xerces-c/program-dom.html#DOMBuilderProperties to learn exactly what type of property value each property returns for replication.

Parameters:

name

The unique identifier (URI) of the property being set.

Returns:: The current value of the property. The pointer spans the same life-time as the parser. A null pointer is returned if nothing was specified externally.

Exceptions:

DOMException

NOT_FOUND_ERR: Raised when the DOMBuilder does not recognize the requested property.

virtual void xercesc::DOMBuilder::setProperty	(	const XMLCh *const	name,
		void *	value
	)			`[pure virtual]`

Set the value of any property in a DOMBuilder.

See http://xml.apache.org/xerces-c/program-dom.html#DOMBuilderProperties for the list of supported properties.

It takes a void pointer as the property value. Application is required to initialize this void pointer to a correct type. See http://xml.apache.org/xerces-c/program-dom.html#DOMBuilderProperties to learn exactly what type of property value each property expects for processing. Passing a void pointer that was initialized with a wrong type will lead to unexpected result. If the same property is set more than once, the last one takes effect.

Parameters:

	name	The unique identifier (URI) of the property being set.
	value	The requested value for the property. See http://xml.apache.org/xerces-c/program-dom.html#DOMBuilderProperties to learn exactly what type of property value each property expects for processing. Passing a void pointer that was initialized with a wrong type will lead to unexpected result.

Exceptions:

DOMException

NOT_FOUND_ERR: Raised when the DOMBuilder does not recognize the requested property.

virtual void xercesc::DOMBuilder::release ( ) [pure virtual]

Called to indicate that this DOMBuilder is no longer in use and that the implementation may relinquish any resources associated with it.

Access to a released object will lead to unexpected result.

virtual void xercesc::DOMBuilder::resetDocumentPool ( ) [pure virtual]

Reset the documents vector pool and release all the associated memory back to the system.

When parsing a document using a DOM parser, all memory allocated for a DOM tree is associated to the DOM document.

If you do multiple parse using the same DOM parser instance, then multiple DOM documents will be generated and saved in a vector pool. All these documents (and thus all the allocated memory) won't be deleted until the parser instance is destroyed.

If you don't need these DOM documents anymore and don't want to destroy the DOM parser instance at this moment, then you can call this method to reset the document vector pool and release all the allocated memory back to the system.

It is an error to call this method if you are in the middle of a parse (e.g. in the mid of a progressive parse).

Exceptions:

IOException

An exception from the parser if this function is called when a parse is in progress.

virtual Grammar* xercesc::DOMBuilder::loadGrammar	(	const DOMInputSource &	source,
		const short	grammarType,
		const bool	toCache = `false`
	)			`[pure virtual]`

Preparse schema grammar (XML Schema, DTD, etc.

) via an input source object.

This method invokes the preparsing process on a schema grammar XML file specified by the DOMInputSource parameter. If the 'toCache' flag is enabled, the parser will cache the grammars for re-use. If a grammar key is found in the pool, no caching of any grammar will take place.

"Experimental - subject to change"

Parameters:

	source	A const reference to the DOMInputSource object which points to the schema grammar file to be preparsed.
	grammarType	The grammar type (Schema or DTD).
	toCache	If `true`, we cache the preparsed grammar, otherwise, no chaching. Default is `false`.

Returns:: The preparsed schema grammar object (SchemaGrammar or DTDGrammar). That grammar object is owned by the parser.

Exceptions:

	SAXException	Any SAX exception, possibly wrapping another exception.
	XMLException	An exception from the parser or client handler code.
	DOMException	A DOM exception as per DOM spec.
