UnionChildIterator
public class UnionChildIterator extends ChildTestIterator (Code)
This class defines a simplified type of union iterator that only tests along the child axes. If the conditions are right, it is much faster than using a UnionPathIterator.


Field Summary
final static  longserialVersionUID
    

Constructor Summary
public  UnionChildIterator()
    

Method Summary
public  shortacceptNode(int n)
     Test whether a specified node is visible in the logical view of a TreeWalker or NodeIterator.
public  voidaddNodeTest(PredicatedNodeTest test)
     Add a node test to the union list.
Parameters:
  test - reference to a NodeTest, which will be added directly to the list of node tests (in other words, it will not be cloned).
public  voidfixupVariables(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.

Field Detail
serialVersionUID
final static long serialVersionUID(Code)




Constructor Detail
UnionChildIterator
public UnionChildIterator()(Code)
Constructor for UnionChildIterator




Method Detail
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 .



addNodeTest
public void addNodeTest(PredicatedNodeTest test)(Code)
Add a node test to the union list.
Parameters:
  test - reference to a NodeTest, which will be added directly to the list of node tests (in other words, it will not be cloned). The parent of this test will be set to this object.



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).
