FilterExprIterator()
Create a FilterExprIterator object.
|
FilterExprIterator(Expression expr)
Create a FilterExprIterator object.
|
| Modifier and Type | Method and Description |
|---|---|
void |
callPredicateVisitors(XPathVisitor visitor)
This will traverse the heararchy, calling the visitor for
each member.
|
boolean |
deepEquals(Expression expr)
Compare this object with another object and see
if they are equal, include the sub heararchy.
|
void |
detach()
Detaches the walker from the set which it iterated over, releasing
any computational resources and placing the iterator in the INVALID
state.
|
void |
fixupVariables(java.util.Vector vars,
int globalsSize)
This function is used to fixup variables from QNames to stack frame
indexes at stylesheet build time.
|
int |
getAnalysisBits()
Get the analysis bits for this walker, as defined in the WalkerFactory.
|
Expression |
getInnerExpression()
Get the inner contained expression of this filter.
|
boolean |
isDocOrdered()
Returns true if all the nodes in the iteration well be returned in document
order.
|
void |
setInnerExpression(Expression expr)
Set the inner contained expression of this filter.
|
void |
setRoot(int context,
java.lang.Object environment)
Initialize the context values for this expression
after it is cloned.

transformation.environment - The environment object.
The environment in which this iterator operates, which should provide:
At this time the exact implementation of this environment is application dependent. Probably a proper interface will be created fairly soon.

fixupVariables in class PredicatedNodeTestvars - List of QNames that correspond to variables. This list
should be searched backwards for the first qualified name that
corresponds to the variable reference qname. The position of the
QName in the vector from the start of the vector will be its position
in the stack frame (but variables above the globalsTop value will need
to be offset to the current stack frame).public Expression getInnerExpression()
