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 Summary |
java.lang.String |
getStringValue()
Convert the value to a string, using the serialization rules. |
EMPTY_VALUE_ARRAY
static final ValueRepresentation[] EMPTY_VALUE_ARRAY
- An empty array of ValueRepresentation objects
getStringValue
java.lang.String getStringValue()
throws XPathException
- 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:
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.
