Detailed Description

<meta name="usage" content="internal"> A class that does incremental counting for support of xsl:number.

This class stores a cache of counted nodes (m_countNodes). It tries to cache the counted nodes in document order... the node count is based on its position in the cache list

Constructor & Destructor Documentation

Counter::Counter	(	MemoryManagerType &	theManager,
		const ElemNumber *	numberElem,
		NodeVectorType &	countNodes
	)

Construct a counter object.

Counter::Counter	(	MemoryManagerType &	theManager,

Member Function Documentation

XalanNode* Counter::getLast

(

)

const

Get the last node in the list.

CountType Counter::getPreviouslyCounted	(	StylesheetExecutionContext &	support,
		const XalanNode *	node
	)		const

Try to find a node that was previously counted.

If found, return a positive integer that corresponds to the count.

Parameters:

node	The node to be counted.

Returns:

The count of the node, or 0 if not found.

Member Data Documentation

NodeVectorType Counter::m_countNodes

A vector of all nodes counted so far.

CountType Counter::m_countNodesStartCount

The start count from where m_countNodes counts from.

In other words, the count of a given node in the m_countNodes vector is node position + m_countNodesStartCount.

const XalanNode* Counter::m_fromNode

The node from where the counting starts.

This is needed to find a counter if the node being counted is not immediatly found in the m_countNodes vector.

const ElemNumber* Counter::m_numberElem

The owning xsl:number element.
