Method Detail

call

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

Evaluate the expression

Specified by:

call in interface Callable

Specified by:

call in interface Function

Parameters:

context - the dynamic evaluation context

arguments - the values of the arguments, supplied as SequenceIterators

Returns:

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

Throws:

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

readFile

public CharSequence readFile(String href,
                    String baseURI,
                    String encoding,
                    XPathContext context)
                      throws XPathException

Supporting routine to load one external file given a URI (href) and a baseURI

Overrides:

readFile in class UnparsedTextFunction

Parameters:

href - the relative URI

baseURI - the base URI

encoding - the character encoding

context - the XPath dynamic context

Returns:

the content of the file

Throws:

XPathException - if the file cannot be read

getAbsoluteURI

public static URI getAbsoluteURI(String href,
                 String baseURI)
                          throws XPathException

Throws:

XPathException

handleIOError

public static XPathException handleIOError(URI absoluteURI,
                           IOException ioErr)

readFile

public static CharSequence readFile(IntPredicate checker,
                    Reader reader)
                             throws IOException,
                                    XPathException

Read the contents of an unparsed text file

Parameters:

checker - NameChecker for checking whether characters are valid XML characters

reader - Reader to be used for reading the file

Returns:

a CharSequence representing the contents of the file

Throws:

IOException - if a failure occurs reading the file

XPathException - if the file contains illegal characters

main

public static void main(String[] args)
                 throws Exception

Throws:

Exception
