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().

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.
