| public | |
| public | UnionPathIterator(Compiler
The Compiler which is creating
this expression. compiler, int The position of this iterator in the
opcode list from the compiler. opPos)Create a UnionPathIterator object, including creation of location path iterators from the opcode list, and call back into the Compiler to create predicate expressions. |
| Modifier and Type | Method and Description |
|---|---|
| public void | addIterator(DTMIterator
non-null reference to a location path iterator. expr)Add an iterator to the union list. |
| public void | callVisitors(ExpressionOwner owner, XPathVisitor visitor)
Overrides com. Implements com. This will traverse the heararchy, calling the visitor for each member. |
| public Object | Returns: A clone of this iterator that holds the same node position.Overrides com. Implements com. Get a cloned LocPathIterator that holds the same position as this iterator. |
| protected LocPathIterator | Returns: New location path iterator.The Compiler which is creating
this expression. compiler, int The position of this iterator in the opPos)Create a new location path iterator. |
| public static LocPathIterator | Returns: Object that is derived from LocPathIterator.The Compiler which is creating
this expression. compiler, int The position of this iterator in the
opcode list from the compiler. opPos)This will return an iterator capable of handling the union of paths given. |
| public boolean | deepEquals(Expression expr)
Overrides com. Compare this object with another object and see if they are equal, include the sub heararchy. |
| public void | detach()
Overrides com. Implements com. Detaches the iterator from the set which it iterated over, releasing any computational resources and placing the iterator in the INVALID state. |
| public void | fixupVariables(List<QName>
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). vars, int globalsSize)Overrides com. This function is used to fixup variables from QNames to stack frame indexes at stylesheet build time. |
| public int | Returns: One of WalkerFactory#BIT_DESCENDANT, etc.Overrides com. Implements com. Get the analysis bits for this walker, as defined in the WalkerFactory. |
| public int | Returns: Axis.CHILD, etc., or -1 if the axis is not known or is of multiple types.Overrides com. Implements com. Returns the axis being iterated, if it is known. |
| protected void | loadLocationPaths(Compiler
The Compiler which is creating
this expression. compiler, int The position of this iterator in the
opcode list from the compiler. opPos, int The insert position of the iterator. count)Initialize the location path iterators. |
| public int | Returns: The nextNode in the set being iterated over, or
null if there are no more members in that set.Implements abstract com. Implements com. Returns the next node in the set and advances the position of the iterator in the set. |
| private void | readObject(ObjectInputStream
Input stream to read from stream)Hides com. Read the object from a serialization stream. |
| public void | setRoot(int
The XPath runtime context for this
transformation. context, Object environment)Overrides com. Implements com. Initialize the context values for this expression after it is cloned. |
