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:
- Serializable, Expression, XSLTFunction
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
