Class LineNumberMap

java.lang.Object
net.sf.saxon.tree.linked.LineNumberMap
public class LineNumberMap extends Object
Line numbers are not held in nodes in the tree, because they are not usually needed. This class provides a map from element sequence numbers to line numbers: it is linked to the root node of the tree.
