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 methode returns the attribute name in a QName format.

const XMLCh * XMLAttr::getName (  )  const

This method gets a const pointer tot he name of the attribute.

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

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.

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.

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.

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.

const XMLCh * XMLAttr::getValidatingTypeURI (  )  const

Returns:
the uri part of DOM Level 3 TypeInfo

Deprecated:

const XMLCh * XMLAttr::getValidatingTypeName (  )  const

Returns:
the name part of DOM Level 3 TypeInfo

Deprecated:
