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. |
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. |

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. |

FilterExprIterator
public FilterExprIterator()
- Create a FilterExprIterator object.
FilterExprIterator
public FilterExprIterator(Expression expr)
- Create a FilterExprIterator object.
setRoot
public void setRoot(int context,
java.lang.Object environment)
- Initialize the context values for this expression
after it is cloned.
- Parameters:
context
- The XPath runtime context for this
transformation.- Overrides:
- setRoot in class LocPathIterator
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.
- Overrides:
- detach in class LocPathIterator
fixupVariables
public 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.
- Parameters:
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).- Overrides:
- fixupVariables in class PredicatedNodeTest
getInnerExpression
public Expression getInnerExpression()
- Get the inner contained expression of this filter.
setInnerExpression
public void setInnerExpression(Expression expr)
- Set the inner contained expression of this filter.
getAnalysisBits
public int getAnalysisBits()
- Get the analysis bits for this walker, as defined in the WalkerFactory.
- Returns:
- One of WalkerFactory#BIT_DESCENDANT, etc.
- Overrides:
- getAnalysisBits in class LocPathIterator
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!
- Returns:
- true as a default.
- Overrides:
- isDocOrdered in class LocPathIterator
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.
- Parameters:
visitor
- The visitor whose appropriate method will be called.- Overrides:
- callPredicateVisitors in class PredicatedNodeTest
deepEquals
public boolean deepEquals(Expression expr)
- Overrides:
- deepEquals in class PredicatedNodeTest
- See Also:
Expression.deepEquals(Expression)
