public interface ValueRepresentation<T extends Item>
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
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. For nodes, it returns the string value of the node as defined in XDM.- Returns:
- the result of converting the value to a string
- Throws:
XPathException
- The method can fail if evaluation of the value has been deferred, and if a failure occurs during the deferred evaluation. It can also occur for values such as function items and maps that have no string value. No failure is possible in the case of an AtomicValue or a Node.

getStringValueCS
java.lang.CharSequence getStringValueCS() throws XPathException
Convert the value to a string, using the serialization rules, and returning the result as a CharSequence. In some cases this may be more efficient than obtaining the result as a string. For atomic values the result is the same as a cast; for sequence values it gives a space-separated list. For nodes, it returns the string value of the node as defined in XDM.- Returns:
- the result of converting the value to a string
- Throws:
XPathException
- The method can fail if evaluation of the value has been deferred, and if a failure occurs during the deferred evaluation. It can also occur for values such as function items and maps that have no string value. No failure is possible in the case of an AtomicValue or a Node.
