Method Detail

call

public Sequence call(XPathContext context,
            Sequence[] arguments)
              throws XPathException

call in interface Callable

Specified by:

call in interface Function

Parameters:

context - the dynamic evaluation context

arguments - the values of the arguments, supplied as Sequence objects

Returns:

the result of the evaluation, in the form of a Sequence

Throws:

XPathException - if a dynamic error occurs during the evaluation of the expression

parse

public DateTimeValue parse(String input,
                  XPathContext context)
                    throws XPathException

Parse a supplied string to obtain a dateTime

Parameters:

input - a string containing the date and time in IETF format

context - the XPath context

Returns:

either a DateTimeValue representing the input supplied, or a ValidationFailure if the input string was invalid

Throws:

XPathException

parseTime

public int parseTime(List<String> tokens,
            int currentPosition,
            List<TimeValue> result,
            String input)
              throws XPathException

Parse part of a string (already tokenized) to obtain a TimeValue

Parameters:

tokens - tokenized string containing the date and time in IETF format

currentPosition - index of current token

result - TimeValue produced from parsing time from tokens

Returns:

index of token after parsing the time

Throws:

XPathException
