Class Serialize

java.lang.Object

net.sf.saxon.expr.ComputedExpression

net.sf.saxon.expr.FunctionCall

net.sf.saxon.functions.SystemFunction

net.sf.saxon.functions.Serialize

All Implemented Interfaces:

java.io.Serializable, javax.xml.transform.SourceLocator, Container, Expression, XSLTFunction, InstructionInfoProvider

public class Serialize
extends SystemFunction
implements XSLTFunction

This class implements the saxon:serialize() extension function, which is specially-recognized by the system because it needs access to parts of the static context

checkArguments

public void checkArguments(StaticContext env)
                    throws XPathException

Method supplied by each class of function to check arguments during parsing, when all the argument expressions have been read

Overrides:

checkArguments in class SystemFunction

Throws:

XPathException

evaluateItem

public Item evaluateItem(XPathContext c)
                  throws XPathException

Evaluate the function

Specified by:

evaluateItem in interface Expression

Overrides:

evaluateItem in class ComputedExpression

Parameters:

c - The context in which the expression is to be evaluated

Returns:

the node or atomic value that results from evaluating the expression; or null to indicate that the result is an empty sequence

Throws:

XPathException - if any dynamic error occurs evaluating the expression
