Detailed Description

DOMBuilder provides an API for parsing XML documents and building the corresponding DOM document tree. A DOMBuilder instance is obtained from the DOMImplementationLS interface by invoking its createDOMBuilder method. This implementation also allows the applications to install an error and an entity handler (useful extensions to the DOM specification).

Member Enumeration Documentation

enum DOMBuilder::ActionType

Action types for use in parseWithContext.

ACTION_REPLACE: Replace the context node with the result of parsing the input source. For this action to work the context node must be an DOMElement, DOMText, DOMCDATASection, DOMComment, DOMProcessingInstruction, or DOMEntityReference node.

ACTION_APPEND: Append the result of parsing the input source to the context node. For this action to work, the context node must be an DOMElement.

ACTION_INSERT_AFTER: Insert the result of parsing the input source after the context node. For this action to work the context nodes parent must be an DOMElement.

ACTION_INSERT_BEFORE: Insert the result of parsing the input source before the context node. For this action to work the context nodes parent must be an DOMElement.

nameSpaceKey Namespace key
Returns:
Grammar associated with the Namespace key.

Implemented in DOMBuilderImpl.

virtual void* 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.

Implemented in DOMBuilderImpl.

virtual Grammar* DOMBuilder::getRootGrammar (  )  const [pure virtual]

virtual void 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

Implemented in DOMBuilderImpl.

virtual void 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.

Implemented in DOMBuilderImpl.

virtual void DOMBuilder::resetCachedGrammarPool (  )  [pure virtual]

Clear the cached grammar pool

Implemented in DOMBuilderImpl.

virtual void 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.

Implemented in DOMBuilderImpl.

virtual void 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

Implemented in DOMBuilderImpl.

virtual void 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

Implemented in DOMBuilderImpl.

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

Set the state of a feature

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.
See also:
setFeature

canSetFeature

Since:
DOM Level 3

Implemented in DOMBuilderImpl.

virtual void 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

Implemented in DOMBuilderImpl.

virtual void 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.
