TreeEnumeration(NodeImpl origin,
NodeTest nodeTest) |
Create an axis enumeration for a given type and name of node, from a given
origin node
|
Modifier and Type | Method | Description |
---|---|---|
protected void |
advance() |
Advance along the axis until a node is found that matches the required criteria
|
protected boolean |
conforms(NodeImpl node) |
Test whether a node conforms to the node type and name constraints.
|
protected int |
count() |
Count the number of nodes in the enumeration.
|
boolean |
hasMoreElements() |
Determine if there are more nodes to be returned
|
boolean |
isPeer() |
Determine if the nodes are guaranteed to be peers (i.e.
|
boolean |
isReverseSorted() |
Determine if the nodes are guaranteed to be sorted in reverse document order
|
boolean |
isSorted() |
Determine if the nodes are guaranteed to be sorted in document order
|
NodeInfo |
nextElement() |
Return the next node in the enumeration
|
protected abstract void |
step() |
