org.apache.xpath.axes.PredicatedNodeTest
All known Subclasses: org.apache.xpath.axes.AxesWalker, org.apache.xpath.axes.LocPathIterator,
| DEBUG_PREDICATECOUNTING | | final static boolean DEBUG_PREDICATECOUNTING(Code) | | If true, diagnostic messages about predicate execution will be posted.
|
| m_foundLast | | protected transient boolean m_foundLast(Code) | | This is true if nextNode returns null.
|
| m_predCount | | protected int m_predCount(Code) | | |
| m_predicateIndex | | transient int m_predicateIndex(Code) | | Which predicate we are executing.
|
| m_proximityPositions | | protected transient int[] m_proximityPositions(Code) | | An array of counts that correspond to the number
of predicates the step contains.
|
| serialVersionUID | | final static long serialVersionUID(Code) | | |
| PredicatedNodeTest | | PredicatedNodeTest(LocPathIterator locPathIterator)(Code) | | Construct an AxesWalker using a LocPathIterator.
Parameters:
locPathIterator - non-null reference to the parent iterator. |
| PredicatedNodeTest | | PredicatedNodeTest()(Code) | | Construct an AxesWalker. The location path iterator will have to be set
before use.
|
| acceptNode | | public short acceptNode(int n)(Code) | | Test whether a specified node is visible in the logical view of a
TreeWalker or NodeIterator. This function will be called by the
implementation of TreeWalker and NodeIterator; it is not intended to
be called directly from user code.
Parameters:
n - The node to check to see if it passes the filter or not. a constant to determine whether the node is accepted,rejected, or skipped, as defined above . |
| callPredicateVisitors | | public void callPredicateVisitors(XPathVisitor visitor)(Code) | | 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. |
| canTraverseOutsideSubtree | | public boolean canTraverseOutsideSubtree()(Code) | | Tell if this expression or it's subexpressions can traverse outside
the current subtree.
true if traversal outside the context node's subtree can occur. |
| countProximityPosition | | protected void countProximityPosition(int i)(Code) | | Count forward one proximity position.
Parameters:
i - The index into the m_proximityPositions array, where the increment will occur. |
| fixupVariables | | public void fixupVariables(java.util.Vector vars, int globalsSize)(Code) | | 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). |
| getLastPos | | abstract public int getLastPos(XPathContext xctxt)(Code) | | Get the index of the last node that can be itterated to.
Parameters:
xctxt - XPath runtime context. the index of the last node that can be itterated to. |
| getLocPathIterator | | public LocPathIterator getLocPathIterator()(Code) | | Get the owning location path iterator.
the owning location path iterator, which should not be null. |
| getPredicate | | public Expression getPredicate(int index)(Code) | | Get a predicate expression at the given index.
Parameters:
index - Index of the predicate. A predicate expression. |
| getPredicateCount | | public int getPredicateCount()(Code) | | Get the number of predicates that this walker has.
the number of predicates that this walker has. |
| getPredicateIndex | | public int getPredicateIndex()(Code) | | Get which predicate is executing.
The current predicate index, or -1 if no predicate is executing. |
| getProximityPosition | | public int getProximityPosition()(Code) | | Get the current sub-context position.
The node position of this walker in the sub-context node list. |
| getProximityPosition | | public int getProximityPosition(XPathContext xctxt)(Code) | | Get the current sub-context position.
Parameters:
xctxt - The XPath runtime context. The node position of this walker in the sub-context node list. |
| getProximityPosition | | protected int getProximityPosition(int predicateIndex)(Code) | | Get the current sub-context position.
Parameters:
predicateIndex - The index of the predicate where the proximity should be taken from. The node position of this walker in the sub-context node list. |
| isReverseAxes | | public boolean isReverseAxes()(Code) | | Tells if this is a reverse axes.
false, unless a derived class overrides. |
| nodeToString | | protected String nodeToString(int n)(Code) | | Diagnostics.
Parameters:
n - Node to give diagnostic information about, or null. Informative string about the argument. |
| resetProximityPositions | | public void resetProximityPositions()(Code) | | Reset the proximity positions counts.
|
| setLocPathIterator | | public void setLocPathIterator(LocPathIterator li)(Code) | | Set the location path iterator owner for this walker. Besides
initialization, this function is called during cloning operations.
Parameters:
li - non-null reference to the owning location path iterator. |
| setPredicateCount | | public void setPredicateCount(int count)(Code) | | Set the number of predicates that this walker has. This does more
that one would think, as it creates a new predicate array of the
size of the count argument, and copies count predicates into the new
one from the old, and then reassigns the predicates value. All this
to keep from having to have a predicate count value.
Parameters:
count - The number of predicates, which must be equal or less than the existing count. |
