Class CurrentDateTime
- EvaluableItem, InstructionInfoProvider, SequenceIterable, Serializable, SourceLocator
public class CurrentDateTime
This class implements the XPath 2.0 functions
current-date(), current-time(), and current-dateTime(), as
well as the function implicit-timezone(). The value that is required
is inferred from the type of result required.

preEvaluate
public Expression preEvaluate(ExpressionVisitor visitor)
preEvaluate: this method suppresses compile-time evaluation by doing nothing
(because the value of the expression depends on the runtime context)
- preEvaluate in interface FunctionCall
visitor - an expression visitor
