Package net.sf.saxon.tree.linked Description
</H2>
<P>
<p>This package defines the implementation of the so-called "standard tree" structure. This
structure can be used to represent both the source document and the stylesheet.
It is no longer the default structure for source documents, but is always used for
stylesheets and for schema documents, because it allows each element to be represented
by a subclass of <code>Element</code> with application-specific functionality.</p>
<p>The classes represent the various kinds of node on the tree. Most of them
are not visible outside the package, with the notable exception of ElementImpl,
which can be subclassed to contain properties for a particular kind of element.
This capability is exploited especially in the stylesheet tree.</p>
<p>As well as classes representing nodes, there are classes representing
iterators over the various XPath axes, for example <code>ChildEnumeration</code>
and <code>PrecedingEnumeration</code>.</p>
<p>The <code>TreeBuilder</code> performs the work of constructing a tree, from a
sequence of SAX-like <code>Receiver</code> events.</p>
<p>The package also contains some helper classes such as <code>SystemIdMap</code>
and <code>LineNumberMap</code> that are used also by the TinyTree implementation.</p>
