Class FilterExprIteratorSimple
- Cloneable, DTMIterator, Serializable, ExpressionNode, PathComponent, Serializable, SourceLocator, SubContextList, XPathVisitable
public class FilterExprIteratorSimple
Class to use for one-step iteration that doesn't have a predicate, and
doesn't need to set the context.
void | callPredicateVisitors(XPathVisitor visitor) - This will traverse the heararchy, calling the visitor for
each member.
|
boolean | deepEquals(Expression expr)
|
void | detach() - Detaches the walker from the set which it iterated over, releasing
any computational resources and placing the iterator in the INVALID
state.
|
static XNodeSet | executeFilterExpr(int context, XPathContext xctxt, PrefixResolver prefixResolver, boolean isTopLevel, int stackFrame, Expression expr) - Execute the expression.
|
void | fixupVariables(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.
|
int | getAxis() - Returns the axis being iterated, if it is known.
|
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.
|
int | nextNode() - Returns the next node in the set and advances the position of the
iterator in the set.
|
void | setInnerExpression(Expression expr) - Set the inner contained expression of this filter.
|
void | setRoot(int context, Object environment) - Initialize the context values for this expression
after it is cloned.

FilterExprIteratorSimple
public FilterExprIteratorSimple()
Create a ChildTestIterator object.
FilterExprIteratorSimple
public FilterExprIteratorSimple(Expression expr)
Create a ChildTestIterator object.
callPredicateVisitors
public void callPredicateVisitors(XPathVisitor visitor)
This will traverse the heararchy, calling the visitor for
each member. If the called visitor method returns
false, the subtree should not be called.
- callPredicateVisitors in interface PredicatedNodeTest
visitor
- The visitor whose appropriate method will be called.
detach
public void detach()
Detaches the walker from the set which it iterated over, releasing
any computational resources and placing the iterator in the INVALID
state.
- detach in interface DTMIterator
- detach in interface LocPathIterator
fixupVariables
public void fixupVariables(Vector vars,
int globalsSize)
This function is used to fixup variables from QNames to stack frame
indexes at stylesheet build time.
- fixupVariables in interface PredicatedNodeTest
vars
- 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).
getAxis
public int getAxis()
Returns the axis being iterated, if it is known.
- getAxis in interface DTMIterator
- getAxis in interface LocPathIterator
- Axis.CHILD, etc., or -1 if the axis is not known or is of multiple
types.
getInnerExpression
public Expression getInnerExpression()
Get the inner contained expression of this filter.
isDocOrdered
public boolean isDocOrdered()
Returns true if all the nodes in the iteration well be returned in document
order.
Warning: This can only be called after setRoot has been called!
- isDocOrdered in interface DTMIterator
- isDocOrdered in interface LocPathIterator
nextNode
public int nextNode()
Returns the next node in the set and advances the position of the
iterator in the set. After a NodeIterator is created, the first call
to nextNode() returns the first node in the set.
- nextNode in interface DTMIterator
- nextNode in interface LocPathIterator
- The next
Node
in the set being iterated over, or
null
if there are no more members in that set.
setInnerExpression
public void setInnerExpression(Expression expr)
Set the inner contained expression of this filter.
