Constructor Details

ChildEnumeration

public ChildEnumeration(NodeImpl node,
                        NodeTest nodeTest)

Method Details

getLastPosition

public int getLastPosition()
Get the last position, that is the number of nodes in the enumeration
Specified by:
getLastPosition in interface AxisEnumeration
getLastPosition in interface LastPositionFinder

isPeer

public boolean isPeer()
Determine whether the nodes returned by this enumeration are known to be peers, that is, no node is a descendant or ancestor of another node. This significance of this property is that if a peer enumeration is applied to each node in a set derived from another peer enumeration, and if both enumerations are sorted, then the result is also sorted.
Specified by:
isPeer in interface NodeEnumeration
Overrides:
isPeer in interface TreeEnumeration

isSorted

public boolean isSorted()
Determine whether the nodes returned by this enumeration are known to be in document order
Specified by:
isSorted in interface NodeEnumeration
Overrides:
isSorted in interface TreeEnumeration
Returns:
true if the nodes are guaranteed to be in document order.

step

protected void step()
Overrides:
step in interface TreeEnumeration
