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
managerThe 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
uriIdThe id into the validator's URI pool of the URI that the prefix mapped to. Only used if namespaces are enabled/supported.
attrNameThe base name of the attribute, i.e. the part after any prefix.
attrPrefixThe prefix, if any, of this attribute's name. If this is empty, then uriID is meaningless as well.
attrValueThe value string of the attribute, which should be fully normalized by XML rules!
typeThe 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!
specifiedIndicates whether the attribute was explicitly specified or not. If not, then it was faulted in from a FIXED or DEFAULT value.
managerThe configurable memory manager
datatypeValidatortype used to validate the attribute, if it was validated by an XML Schema
isSchematrue 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
uriIdThe id into the validator's URI pool of the URI that the prefix mapped to. Only used if namespaces are enabled/supported.
rawNameThe raw name of the attribute.
attrValueThe value string of the attribute, which should be fully normalized by XML rules!
typeThe 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!
specifiedIndicates whether the attribute was explicitly specified or not. If not, then it was faulted in from a FIXED or DEFAULT value.
managerThe configurable memory manager
datatypeValidatortype used to validate the attribute, if it was validated by an XML Schema
isSchematrue 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
uriIdThe id into the validator's URI pool of the URI that the prefix mapped to. Only used if namespaces are enabled/supported.
attrNameThe base name of the attribute, i.e. the part after any prefix.
attrPrefixThe prefix, if any, of this attribute's name. If this is empty, then uriID is meaningless as well.
attrValueThe value string of the attribute, which should be fully normalized by XML rules according to the attribute type.
typeThe 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!
datatypeValidatortype used to validate the attribute, if it was validated by an XML Schema
isSchematrue 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
uriIdThe id into the validator's URI pool of the URI that the prefix mapped to. Only used if namespaces are enabled/supported.
attrRawNameThe raw name of the attribute.
attrValueThe value string of the attribute, which should be fully normalized by XML rules according to the attribute type.
typeThe 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!
datatypeValidatortype used to validate the attribute, if it was validated by an XML Schema
isSchematrue 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
uriIdThe id into the validator's URI pool of the URI that the prefix mapped to. Only used if namespaces are enabled/supported.
attrNameThe base name of the attribute, i.e. the part after any prefix.
attrPrefixThe 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
newValueIndicates 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
newTypeThe 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
uriIdThe uriId of the attribute.
void XMLAttr::setValue ( const XMLCh *const  newValue)

This method will update the value field of the attribute.

Parameters
