Class NodeListExpression
public class NodeListExpression
A NodeListExpression is an expression denoting a set of nodes sorted in document order.
It is not possible to write a NodeListExpression directly using XPath; however a node set
expression is treated as a NodeListExpression when it appears in certain contexts, specifically
the select attribute of xsl:apply-templates or xsl:for-each.

NodeListExpression
public NodeListExpression(Expression exp)
Constructor
exp
- The expression that delivers the unsorted node-set
display
public void display(int level)
Diagnostic print of expression structure
- display in interface Expression
getDependencies
public int getDependencies()
Determine which aspects of the context the expression depends on. The result is
a bitwise-or'ed value composed from constants such as Context.VARIABLES and
Context.CURRENT_NODE
- getDependencies in interface Expression
reduce
public Expression reduce(int dependencies,
Context context)
throws XPathException
Perform a partial evaluation of the expression, by eliminating specified dependencies
on the context.
- reduce in interface Expression
dependencies
- The dependencies to be removedcontext
- The context to be used for the partial evaluation
- a new expression that does not have any of the specified
dependencies
