static XPathConstructionContextDefault* XPathConstructionContextDefault::create ( MemoryManager &  theManager)

static

virtual XalanDOMString& XPathConstructionContextDefault::getCachedString ( )

virtual

Get a cached string for temporary use.

Returns

A reference to the string

Implements XPathConstructionContext.

virtual const XalanDOMString& XPathConstructionContextDefault::getPooledString ( const XalanDOMString &  theString)

virtual

Get a pooled string given the source string.

If the string already exists in the pool, no copy will be made. If not, a copy will be made and kept for later use.

Parameters

theString

The source string

Returns

a const reference to a pooled string.

Implements XPathConstructionContext.

virtual const XalanDOMString& XPathConstructionContextDefault::getPooledString ( const XalanDOMChar *  theString, XalanDOMString::size_type  theLength = XalanDOMString::npos  )

virtual

Get a pooled string given the source character array.

If the string already exists in the pool, no copy will be made. If not, a copy will be made and kept for later use.

Parameters

theString	The source character array
theLength	The length of the character array

Returns

a const reference to a pooled string.

Implements XPathConstructionContext.

virtual void XPathConstructionContextDefault::problem ( eSource  source, eClassification  classification, const XalanDOMString &  msg, const Locator *  locator, const XalanNode *  sourceNode  )

virtual

Function that is called when a problem event occurs.

Parameters

source	Either eXMLParser, eXSLProcessor, or eXPATH.
classification	Either eMessage, eWarning, or eError.
locator	The current Locator instance for the stylesheet. Maybe be a null pointer.
sourceNode	The current source node, if any.
msg	The error message.

Implements XPathConstructionContext.

virtual void XPathConstructionContextDefault::problem ( eSource  source, eClassification  classification, const XalanDOMString &  msg, const XalanNode *  sourceNode  )

virtual

Function that is called when a problem event occurs.

This version assumes location information is already formatted into the message.

Parameters

source	either eXMLPARSER, eXSLPROCESSOR, or eXPATH
classification	either eMESSAGE, eERROR or eWARNING
msg	string message explaining the problem.

Implements XPathConstructionContext.

virtual bool XPathConstructionContextDefault::releaseCachedString ( XalanDOMString &  theString)

virtual

Return a cached string.

Parameters

theString

The string to release.

Returns

true if the string was released successfully.

Implements XPathConstructionContext.

virtual void XPathConstructionContextDefault::reset ( )

virtual

Reset the instance.

Any existing objects created by the instance will be destroyed.

Implements XPathConstructionContext.
