Detailed Description

This abstract class defines an interface for fast, forward-only access to XML data. An object belonging to a derived-class implementation of this protocol is required to be re-usable, such that a new XML document can be parsed using the same reader object by calling close followed by another open.

See balxml_reader

Member Typedef Documentation

◆ StreamBufPtr

typedef bslma::ManagedPtr<bsl::streambuf> balxml::Reader::StreamBufPtr

◆ XmlResolverFunctor

typedef bsl::function<StreamBufPtr(const char *location, const char *namespaceUri)> balxml::Reader::XmlResolverFunctor

Type for a user supplied functor that finds and opens an external resource for the specified location and/or namespaceUri and returns that resource as a managed pointer to a stream. The location argument specifies the location of the external resource and is typically a filename or a URI, depending on the context. The namespaceUri argument always refers to the XML namespace of the entity to be resolved. A conforming functor returns an empty managed pointer if it cannot resolve the resource. For example, the reader may use a resolver to open an external entity, even if the reader does not do validation (see definition of <!ENTITY> in the XML standard). Note that either argument can be NULL in situations where its value is not needed or can be computed from the other argument.

Constructor & Destructor Documentation

◆ ~Reader()

virtual balxml::Reader::~Reader ( void )

virtual

Destroy this object. The implementation for this pure abstract base class does nothing.

Member Function Documentation

◆ advanceToNextNode()

virtual int balxml::Reader::advanceToNextNode ( )

pure virtual

Move to the next node in the data steam created by open thus allowing the node's properties to be queried via the Reader accessors. Return 0 on successful read, 1 if there are no more nodes to read, and a negative number otherwise. Note that each call to advanceToNextNode invalidates strings and data structures returned when Reader accessors where call for the "prior node". E.g., the pointer returned from nodeName for this node will not be valid once advanceToNextNode is called. Note that the reader will not be on a valid node until the first call to advanceToNextNode after the reader is opened. TBD: add comment about insignificant white space.

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

◆ close()

virtual void balxml::Reader::close ( )

pure virtual

Close the reader. Most, but not all state is reset. Specifically, the XML resource resolver and the prefix stack remain. The prefix stack shall be returned to the stack depth it had when setPrefixStack was called. Call the method open to reuse the reader. Note that close invalidates all strings and data structures obtained via Reader accessors. E.g., the pointer returned from nodeName for this node will not be valid once close is called.

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

◆ documentEncoding()

virtual const char * balxml::Reader::documentEncoding ( ) const

pure virtual

Return the document encoding or NULL on error. The returned pointer is owned by this object and must not be modified or deallocated by the caller. The returned pointer becomes invalid when close is called or the reader is destroyed.

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

◆ dumpNode()

void balxml::Reader::dumpNode ( bsl::ostream & os ) const

Print the information about the current node to the specified output os stream.

◆ errorInfo()

virtual const ErrorInfo & balxml::Reader::errorInfo ( ) const

pure virtual

Return a reference to the non-modifiable error information for this reader. The returned value becomes invalid when close is called or the reader is destroyed.

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

◆ getColumnNumber()

virtual int balxml::Reader::getColumnNumber ( ) const

pure virtual

Return the current column number within the input stream. The current column number is the number of characters since the last newline was read by the reader plus one, i.e., the first column of each line is column number one. Return 0 if not available. Note that a derived-class implementation is not required to count columns and may just return 0.

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

◆ getLineNumber()

virtual int balxml::Reader::getLineNumber ( ) const

pure virtual

Return the current line number within the input stream. The current line is the last line for which the reader has not yet seen a newline. Lines are counted starting at one from the time a stream is provided to open. Return 0 if not available. Note that a derived-class implementation is not required to count lines and may just return 0.

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

◆ isEmptyElement()

virtual bool balxml::Reader::isEmptyElement ( ) const

pure virtual

Return true if the current node is an element (i.e., node type is BAEXML_NODE_TYPE_ELEMENT) that ends with />; and false otherwise. Note that <a/> will be considered empty but <a></a> will not.

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

◆ isError()

bool balxml::Reader::isError ( ) const

inline

Return true if the derived object encountered a error. This method is equivalent to a call to errorInfo().isError();

◆ isFatalError()

bool balxml::Reader::isFatalError ( ) const

inline

Return true if the derived object encountered a fatal error. This method is equivalent to a call to errorInfo().isFatalError();

◆ isOpen()

virtual bool balxml::Reader::isOpen ( ) const

pure virtual

Return true if open was called successfully and close has not yet been called and false otherwise.

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

◆ isWarning()

bool balxml::Reader::isWarning ( ) const

inline

Return true if the derived object encountered a warning. This method is equivalent to a call to errorInfo().isWarning();

◆ lookupAttribute() [1/4]

virtual int balxml::Reader::lookupAttribute	(	ElementAttribute *	attribute,
		const char *	localName,
		const char *	namespaceUri
	)		const

pure virtual

Find the attribute with the specified localName and specified namespaceUri in the current node, and fill in the specified attribute structure. Return 0 on success, 1 if there is no attribute found with localName and namespaceUri, and a negative value otherwise. If namespaceUri == 0 or a blank string is passed, then the document's default namespace will be used. The strings that were filled into the attribute structure are invalid upon the next advanceToNextNode or close is called.

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

pure virtual

Find the attribute with the specified localName and specified namespaceId in the current node, and fill in the specified attribute structure. Return 0 on success, 1 if there is no attribute found with localName and namespaceId, and a negative value otherwise. If namespaceId == -1, then the document's default namespace will be used. The strings that were filled into the attribute structure are invalid upon the next advanceToNextNode or close is called.

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

◆ lookupAttribute() [3/4]

virtual int balxml::Reader::lookupAttribute	(	ElementAttribute *	attribute,
		const char *	qname
	)		const

pure virtual

Find the attribute with the specified qname (qualified name) in the current node, and fill in the specified attribute structure.

◆ lookupAttribute() [4/4]

virtual int balxml::Reader::lookupAttribute	(	ElementAttribute *	attribute,
		int	index
	)		const

pure virtual

pure virtual

Set up the reader for parsing using the data contained in the specified (XML) stream, set the base URL to the optionally specified url and set the encoding value to the optionally specified encoding ("ASCII", "UTF-8", etc). Return 0 on success and non-zero otherwise. If url is null or a blank string is passed, then base URL will be empty. The encoding passed to Reader::open will take effect only when there is no encoding information in the original document, i.e., the encoding information obtained from the (XML) stream trumps all. If there is no encoding provided within the document and encoding is null or a blank string is passed, then set the encoding to the default "UTF-8".

pure virtual

Set up the reader for parsing using the data contained in the specified (XML) buffer of the specified size, set the base URL to the optionally specified url and set the encoding value to the optionally specified encoding ("ASCII", "UTF-8", etc). Return 0 on success and non-zero otherwise. If url is null or a blank string is passed, then base URL will be empty. The encoding passed to Reader::open will take effect only when there is no encoding information in the original document, i.e., the encoding information obtained from the (XML) buffer trumps all. If there is no encoding provided within the document and encoding is null or a blank string is passed, then set the encoding to the default "UTF-8". It is an error to open a reader that is already open. Note that the reader will not be on a valid node until advanceToNextNode is called.

Set up the reader for parsing using the data contained in the XML file described by the specified filename, and set the encoding value to the optionally specified encoding ("ASCII", "UTF-8", etc). Returns 0 on success and non-zero otherwise. The encoding passed to Reader::open will take effect only when there is no encoding information in the original document, i.e., the encoding information obtained from the XML file described by the filename trumps all. If there is no encoding provided within the document and encoding is null or a blank string is passed, then set the encoding to the default "UTF-8". It is an error to open a reader that is already open. Note that the reader will not be on a valid node until advanceToNextNode is called.

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

◆ options()

virtual unsigned int balxml::Reader::options ( ) const

pure virtual

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

◆ prefixStack()

virtual PrefixStack * balxml::Reader::prefixStack ( ) const

pure virtual

Return a pointer to the modifiable prefix stack that is used by this reader to manage namespace prefixes or 0 if namespace support is disabled. The behavior is undefined if the returned prefix stack is augmented in any way after calling open and before calling close.

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

◆ resolver()

virtual XmlResolverFunctor balxml::Reader::resolver ( ) const

pure virtual

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

◆ setOptions()

virtual void balxml::Reader::setOptions ( unsigned int flags )

pure virtual

Set the options to the flags in the specified flags. The options for the reader are persistent, i.e., the options are not reset by close. The behavior is undefined if this method is called after calling open and before calling close; except that derived classes are permitted to specify valid behavior for calling this function for specific arguments while the reader is open.

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

◆ setPrefixStack()

virtual void balxml::Reader::setPrefixStack ( PrefixStack * prefixes )

pure virtual

Set the prefix stack to the stack at the optionally specified prefixes address or disable prefix stack support if prefixes is null. This stack is used to push and pop namespace prefixes as the parse progresses, so that, at any point, the stack will reflect the set of active prefixes for the current node. It is legitimate to pass a stack that already contains prefixes, these prefixes shall be preserved when close is called, i.e., the prefix stack shall be returned to the stack depth it had when setPrefixStack was called. The behavior is undefined if this method is called after calling open and before calling close.

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.

◆ setResolver()

virtual void balxml::Reader::setResolver ( XmlResolverFunctor resolver )

pure virtual

Set the external XML resource resolver to the specified resolver. The XML resource resolver is used by the balxml_reader to find and open an external resources (See the XmlResolverFunctor typedef for more details). The XML resource resolver remains valid; it is not affected by a call to close and should be available until the reader is destroyed. The behavior is undefined if this method is called after calling open and before calling close.

Implemented in balxml::MiniReader, and balxml::Utf8ReaderWrapper.
