Interface ValueRepresentation

public interface ValueRepresentation

A ValueRepresentation is a representation of a Value. This is a marker interface used to represent the union of two classes: Value, and NodeInfo. Either of these two classes can be used to represent a value. The class is used primarily to represent the value of a variable.

This class is intended primarily for internal use, and should not be considered part of the Saxon public API.

Method Detail

getStringValue

public String getStringValue()
Convert the value to a string, using the serialization rules. For atomic values this is the same as a cast; for sequence values it gives a space-separated list.

Throws: net.sf.saxon.trans.XPathException The method can fail if evaluation of the value has been deferred, and if a failure occurs during the deferred evaluation. No failure is possible in the case of an AtomicValue.
