## Detailed Description

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

## Member Typedef Documentation

typedef unsigned long Counter::CountType

typedef XalanVector< XalanNode *> Counter::NodeVectorType<XalanNode*>

## Constructor & Destructor Documentation

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

| Construct a counter object.

Counter::Counter ( | MemoryManagerType & theManager,
| const ElemNumber * numberElem = 0 )

| Construct a counter object.

Counter::Counter ( | const Counter & other,
| 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.
