Detailed Description

This class defines the information about an attribute that will come out of the scanner during parsing.

This information does not depend upon the type of validator because it is not tied to any scheme/DTD type info. Its just the raw XML 1.0 information that will be reported about an attribute in the startElement() callback method of the XMLDocumentHandler class. Hence it is not intended to be extended or derived from. Its designed to be used as is.

The 'specified' field of this class indicates whether the attribute was actually present or whether it was faulted in because it had a fixed or default value.

The code receiving this information can ask its validator for more info about the attribute, i.e. get its declaration from the DTD/Schema info.

Because of the heavy use (and reuse) of instances of this class, and the number of string members it has, this class takes pains to not reallocate string members unless it has to. It keeps up with how long each buffer is and only reallocates if the new value won't fit.

Constructor & Destructor Documentation

XMLAttr::XMLAttr ( MemoryManager *const manager = XMLPlatformUtils::fgMemoryManager )

The default constructor just setsup an empty attribute to be filled in the later.

Though the initial state is a reasonable one, it is not documented because it should not be depended on.

Parameters

manager The configurable memory manager

XMLAttr::XMLAttr	(	const unsigned int	uriId,
		const XMLCh *const	attrName,
		const XMLCh *const	attrPrefix,
		const XMLCh *const	attrValue,
		const XMLAttDef::AttTypes	type = `XMLAttDef::CData`,
		const bool	specified = `true`,
		MemoryManager *const	manager = `XMLPlatformUtils::fgMemoryManager`,
		DatatypeValidator *	datatypeValidator = `0`,
		const bool	isSchema = `false`
	)

This is the primary constructor which takes all of the information required to construct a complete attribute object.

Parameters

uriId	The id into the validator's URI pool of the URI that the prefix mapped to. Only used if namespaces are enabled/supported.
attrName	The base name of the attribute, i.e. the part after any prefix.
attrPrefix	The prefix, if any, of this attribute's name. If this is empty, then uriID is meaningless as well.
attrValue	The value string of the attribute, which should be fully normalized by XML rules!
type	The type of the attribute. This will indicate the type of normalization done and constrains the value content. Make sure that the value set meets the constraints!
specified	Indicates whether the attribute was explicitly specified or not. If not, then it was faulted in from a FIXED or DEFAULT value.
manager	The configurable memory manager
datatypeValidator	type used to validate the attribute, if it was validated by an XML Schema
isSchema	true if and only if this attribute was validated by an XML Schema

XMLAttr::XMLAttr	(	const unsigned int	uriId,
		const XMLCh *const	rawName,
		const XMLCh *const	attrValue,
		const XMLAttDef::AttTypes	type = `XMLAttDef::CData`,
		const bool	specified = `true`,
		MemoryManager *const	manager = `XMLPlatformUtils::fgMemoryManager`,
		DatatypeValidator *	datatypeValidator = `0`,
		const bool	isSchema = `false`
	)

This is the primary constructor which takes all of the information required to construct a complete attribute object.

Parameters

uriId	The id into the validator's URI pool of the URI that the prefix mapped to. Only used if namespaces are enabled/supported.
rawName	The raw name of the attribute.
attrValue	The value string of the attribute, which should be fully normalized by XML rules!
type	The type of the attribute. This will indicate the type of normalization done and constrains the value content. Make sure that the value set meets the constraints!
specified	Indicates whether the attribute was explicitly specified or not. If not, then it was faulted in from a FIXED or DEFAULT value.
manager	The configurable memory manager
datatypeValidator	type used to validate the attribute, if it was validated by an XML Schema
isSchema	true if and only if this attribute was validated by an XML Schema

Member Function Documentation

QName * XMLAttr::getAttName ( ) const

This method returns the attribute name in a QName format.

const XMLCh * XMLAttr::getName ( ) const

This method gets a const pointer to the name of the attribute.

The form of this name is defined by the validator in use.

References QName::getLocalPart().

const XMLCh * XMLAttr::getPrefix ( ) const

This method will get a const pointer to the prefix string of this attribute.

Since prefixes are optional, it may be zero.

References QName::getPrefix().

const XMLCh* XMLAttr::getQName ( ) const

This method will get the QName of this attribute, which will be the prefix if any, then a colon, then the base name.

If there was no prefix, its the same as the getName() method.

bool XMLAttr::getSpecified ( ) const

This method will get the specified flag, which indicates whether the attribute was explicitly specified or just faulted in.

XMLAttDef::AttTypes XMLAttr::getType ( ) const

This method will get the type of the attribute.

The available types are defined by the XML specification.

unsigned int XMLAttr::getURIId ( ) const

This method will get the id of the URI that this attribute's prefix mapped to.

If namespaces are not on, then its value is meaningless.

References QName::getURI().

const XMLCh * XMLAttr::getValue ( ) const

This method will get the value of the attribute.

The value can be be an empty string, but never null if the object is correctly set up.

void XMLAttr::set	(	const unsigned int	uriId,
		const XMLCh *const	attrName,
		const XMLCh *const	attrPrefix,
		const XMLCh *const	attrValue,
		const XMLAttDef::AttTypes	type = `XMLAttDef::CData`,
		DatatypeValidator *	datatypeValidator = `0`,
		const bool	isSchema = `false`
	)

This method is called to set up a default constructed object after the fact, or to reuse a previously used object.

Parameters

uriId	The id into the validator's URI pool of the URI that the prefix mapped to. Only used if namespaces are enabled/supported.
attrName	The base name of the attribute, i.e. the part after any prefix.
attrPrefix	The prefix, if any, of this attribute's name. If this is empty, then uriID is meaningless as well.
attrValue	The value string of the attribute, which should be fully normalized by XML rules according to the attribute type.
type	The type of the attribute. This will indicate the type of normalization done and constrains the value content. Make sure that the value set meets the constraints!
datatypeValidator	type used to validate the attribute, if it was validated by an XML Schema
isSchema	true if and only if this attribute was validated by an XML Schema

References QName::setName(), and setValue().

void XMLAttr::set	(	const unsigned int	uriId,
		const XMLCh *const	attrRawName,
		const XMLCh *const	attrValue,
		const XMLAttDef::AttTypes	type = `XMLAttDef::CData`,
		DatatypeValidator *	datatypeValidator = `0`,
		const bool	isSchema = `false`
	)

This method is called to set up a default constructed object after the fact, or to reuse a previously used object.

Parameters

uriId	The id into the validator's URI pool of the URI that the prefix mapped to. Only used if namespaces are enabled/supported.
attrRawName	The raw name of the attribute.
attrValue	The value string of the attribute, which should be fully normalized by XML rules according to the attribute type.
type	The type of the attribute. This will indicate the type of normalization done and constrains the value content. Make sure that the value set meets the constraints!
datatypeValidator	type used to validate the attribute, if it was validated by an XML Schema
isSchema	true if and only if this attribute was validated by an XML Schema

References QName::setName(), and setValue().

void XMLAttr::setName	(	const unsigned int	uriId,
		const XMLCh *const	attrName,
		const XMLCh *const	attrPrefix
	)

This method will update just the name related fields of the attribute object.

The other fields are left as is.

Parameters

uriId	The id into the validator's URI pool of the URI that the prefix mapped to. Only used if namespaces are enabled/supported.
attrName	The base name of the attribute, i.e. the part after any prefix.
attrPrefix	The prefix, if any, of this attribute's name. If this is empty, then uriID is meaningless as well.

void XMLAttr::setSpecified ( const bool newValue )

This method will update the specified state of the object.

Parameters

newValue Indicates whether the attribute was explicitly specified or not. If not, then it was faulted in from a FIXED or DEFAULT value.

void XMLAttr::setType ( const XMLAttDef::AttTypes newType )

This method will update the attribute type of the object.

Parameters

newType The type of the attribute. This will indicate the type of normalization done and constrains the value content. Make sure that the value set meets the constraints!

void XMLAttr::setURIId ( const unsigned int uriId )

This method will set the URI id field of this attribute.

This is generally only ever called internally by the parser itself during the parsing process.

Parameters

uriId The uriId of the attribute.

void XMLAttr::setValue ( const XMLCh *const newValue )

This method will update the value field of the attribute.

Parameters

newValue The value string of the attribute, which should be fully normalized by XML rules according to the attribute type.
