PathMap.PathMapNodeSet |
addToPathMap(PathMap pathMap,
PathMap.PathMapNodeSet pathMapNodeSet)
Add a representation of this expression to a PathMap.
|
void |
checkArguments(ExpressionVisitor visitor)
Method called during static type checking
|
int |
computeCardinality()
Determine the cardinality of the function.
|
int |
computeSpecialProperties()
Get the static properties of this expression (other than its type).
|
Expression |
copy()
Copy an expression.
|
Item |
evaluateItem(XPathContext context)
Evaluate the expression
|
java.lang.String |
getStaticBaseURI()
Get the static base URI of the expression
|
boolean |
isReadOnce()
Ask whether this document has been marked as being read once only.
|
Expression |
preEvaluate(ExpressionVisitor visitor)
preEvaluate: this method suppresses compile-time evaluation unless a configuration option has been
set to allow early evaluation.
|
void |
sendDocument(XPathContext context,
Receiver out)
Copy the document identified by this expression to a given Receiver.
|
void |
setReadOnce(boolean once)
Indicate that the document will be read once only (or that it should be treated as if it
is read once only.
