Public Member Functions | |
virtual P6R::P6INT32 | addref ()=0 |
This method increases the reference count of the component instance by one. | |
virtual P6R::P6ERR | getIndexByQName (P6SAX2STRING *pQName, P6UINT32 *pIndex)=0 |
Given the full qualified name (i.e., <namespace>:<attribute name>, like 'X:abc='), return the index value into an array of all attributes stored in this object. | |
virtual P6R::P6ERR | getIndexByURI (P6SAX2STRING *pURI, P6SAX2STRING *pLocalName, P6UINT32 *pIndex)=0 |
Given the namespace URI and local name (e.g., given 'X:abc=', 'abc' is referred to as the local name) return the index value into an array of all attributes stored in this object. | |
virtual P6R::P6ERR | getLength (P6UINT32 *pLength)=0 |
Return the number of attributes in the attribute array stored in this object. | |
virtual P6R::P6ERR | getLocalName (P6UINT32 index, P6SAX2STRING *pString)=0 |
Get the local name of the attribute identified by index into the attribute list. | |
virtual P6R::P6ERR | getQName (P6UINT32 index, P6SAX2STRING *pString)=0 |
Get the QName of the attribute identified by index into the attribute list. | |
virtual P6R::P6ERR | getTypeByIndex (P6UINT32 index, P6SAX2STRING *pString)=0 |
Get the attributes type identified by index into the attribute list. | |
virtual P6R::P6ERR | getTypeByQName (P6SAX2STRING *pQName, P6SAX2STRING *pString)=0 |
Get the attributes type identified by QName as a lookup key into the attribute list. | |
virtual P6R::P6ERR | getTypeByURI (P6SAX2STRING *pURI, P6SAX2STRING *pLocalName, P6SAX2STRING *pString)=0 |
Get the attributes type identified by a namespace as a lookup key into the attribute list. | |
virtual P6R::P6ERR | getURI (P6UINT32 index, P6SAX2STRING *pString)=0 |
Get the URI that is associated with the attribute located at index in the attribute list stored in this object. | |
virtual P6R::P6ERR | getValueByIndex (P6UINT32 index, P6SAX2STRING *pString)=0 |
Find an attribute via an index into an attribute list. | |
virtual P6R::P6ERR | getValueByQName (P6SAX2STRING *pQName, P6SAX2STRING *pString)=0 |
Find an attribute using a QName as a lookup key. | |
virtual P6R::P6ERR | getValueByURI (P6SAX2STRING *pURI, P6SAX2STRING *pLocalName, P6SAX2STRING *pString)=0 |
Find an attribute using a namespace as a lookup key. | |
virtual P6R::P6ERR | queryInterface (const P6R::IID &iid, P6R::P6VOID **ppIface)=0 |
This method queries the component for a specific interface. | |
virtual P6R::P6INT32 | release ()=0 |
This method decrements a components reference count. |
This interface is created by the p6ISAX2XMLReader component and returned to the application via the P6R::p6ISAX2ContentHandler::startElement() method.
Note, that P6SAX2STRING points into the application's buffer passed into the p6IDataStream::processStream() method. Thus these pointers are only valid as long as the XML Reader holds the buffer. Also P6SAX2STRING variables that define namespace items (i.e., URI) are only valid as long as that namespace is in scope. Once the namespace goes out of scope then all strings for that namespace are freed.
The benefits of this pointer design is that the XML Reader does very few internal memory allocations and copying of XML data. The using application should use the pointers immediately when they are provided during a callback to p6ISAX2ContentHandler component or make a copy of the data itself.
