Sequence |
call(XPathContext context,
Sequence[] arguments)
Evaluate the expression
|
Item |
evaluateItem(XPathContext context)
This method handles evaluation of the function:
it returns a StringValue in the case of unparsed-text(), or a BooleanValue
in the case of unparsed-text-available().

static java.net.URI |
getAbsoluteURI(java.lang.String href,
java.lang.String baseURI) |
static XPathException |
handleIOError(java.net.URI absoluteURI,
java.io.IOException ioErr) |
SequenceIterator |
iterate(XPathContext context)
Return an Iterator to iterate over the values of a sequence.
|
static void |
main(java.lang.String[] args) |
static java.lang.CharSequence |
readFile(IntPredicate checker,
java.io.Reader reader)
Read the contents of an unparsed text file
|
java.lang.CharSequence |
readFile(java.lang.String href,
java.lang.String baseURI,
java.lang.String encoding,
XPathContext context)
Supporting routine to load one external file given a URI (href) and a baseURI
