java.lang.Object
  org.apache.xalan.xsltc.dom.NodeSortRecord

public abstract class NodeSortRecord
extends java.lang.Object

Base class for sort records containing application specific sort keys

Field Summary

static int	COMPARE_ASCENDING
static int	COMPARE_DESCENDING
static int	COMPARE_NUMERIC

Constructor Summary

NodeSortRecord()

NodeSortRecord(int node)
This constructor is run by a call to ClassLoader in the makeNodeSortRecord method in the NodeSortRecordFactory class.

Method Summary

int	compareDocOrder(NodeSortRecord other)
int	compareTo(NodeSortRecord other) Compare this sort element to another.
abstract java.lang.String	extractValueFromDOM(DOM dom, int current, int level, AbstractTranslet translet, int last) Extract the sort value for a level of this key.
java.text.Collator[]	getCollator() Returns the array of Collators used for text comparisons in this object.
int	getNode() Returns the node for this sort object
void	initialize(int node, int last, DOM dom, org.apache.xalan.xsltc.dom.SortSettings settings) This method allows the caller to set the values that could not be passed to the default constructor.

Constructor Detail

NodeSortRecord

public NodeSortRecord(int node)

This constructor is run by a call to ClassLoader in the makeNodeSortRecord method in the NodeSortRecordFactory class. Since we cannot pass any parameters to the constructor in that case we just set the default values here and wait for new values through initialize().

NodeSortRecord

public NodeSortRecord()

Method Detail

initialize

public final void initialize(int node,
                             int last,
                             DOM dom,
                             org.apache.xalan.xsltc.dom.SortSettings settings)
                      throws TransletException

This method allows the caller to set the values that could not be passed to the default constructor.

Throws:

TransletException

getNode

public final int getNode()

Returns the node for this sort object

compareDocOrder

public final int compareDocOrder(NodeSortRecord other)

compareTo

public int compareTo(NodeSortRecord other)

Compare this sort element to another. The first level is checked first, and we proceed to the next level only if the first level keys are identical (and so the key values may not even be extracted from the DOM) !!!!MUST OPTIMISE - THIS IS REALLY, REALLY SLOW!!!!

getCollator

public java.text.Collator[] getCollator()

Returns the array of Collators used for text comparisons in this object. May be overridden by inheriting classes

extractValueFromDOM

public abstract java.lang.String extractValueFromDOM(DOM dom,
                                                     int current,
                                                     int level,
                                                     AbstractTranslet translet,
                                                     int last)

Extract the sort value for a level of this key.
