public class CountersTable

extends Hashtable

This is a table of counters, keyed by ElemNumber objects, each of which has a list of Counter objects. This really isn't a true table, it is more like a list of lists (there must be a technical term for that...).

Constructor Detail

CountersTable

public CountersTable()

Construct a CountersTable.

Method Detail

getCounters

Vector getCounters(ElemNumber numberElem)

Get the list of counters that corresponds to the given ElemNumber object.

Parameters:

numberElem - the given xsl:number element.

Returns:

the list of counters that corresponds to the given ElemNumber object.

putElemNumber

Vector putElemNumber(ElemNumber numberElem)

Put a counter into the table and create an empty vector as it's value.

Parameters:

numberElem - the given xsl:number element.

Returns:

an empty vector to be used to store counts for this number element.

appendBtoFList

void appendBtoFList(NodeSetDTM flist,
                    NodeSetDTM blist)

Add a list of counted nodes that were built in backwards document order, or a list of counted nodes that are in forwards document order.

Parameters:

flist - Vector of nodes built in forwards document order

blist - Vector of nodes built in backwards document order

countNode

public int countNode(XPathContext support,
                     ElemNumber numberElem,
                     int node)
              throws javax.xml.transform.TransformerException

Count forward until the given node is found, or until we have looked to the given amount.

Parameters:

support - The XPath context to use

numberElem - The given xsl:number element.

node - The node to count.

Returns:

The node count, or 0 if not found.

Throws:

javax.xml.transform.TransformerException
