Modifier and Type | Method and Description |
---|---|
void |
checkArguments(ExpressionVisitor visitor)
Method called during static type checking
|
int |
computeSpecialProperties()
Determine the special properties of this 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().
|
SequenceIterator |
iterate(XPathContext context)
Return an Iterator to iterate over the values of a sequence.
|
static void |
main(String[] args) |
Expression |
preEvaluate(ExpressionVisitor visitor)
preEvaluate: this method suppresses compile-time evaluation by doing nothing
|
static CharSequence |
readFile(NameChecker checker,
Reader reader)
Read the contents of an unparsed text file
