Parameters:
other -

getLength

public int getLength()
Description copied from class: AbstractNodeSet
Return the number of nodes contained in this node set.

Specified by:
getLength in interface Sequence
Specified by:
getLength in class AbstractNodeSet

item

public org.w3c.dom.Node item(int pos)
Specified by:
item in interface org.w3c.dom.NodeList
Specified by:
item in class AbstractNodeSet

get

public NodeProxy get(int pos)
Description copied from class: AbstractNodeSet

get

public final NodeProxy get(NodeProxy p)
Description copied from class: AbstractNodeSet
Get a node from this node set matching the document and node id of the given NodeProxy.

Specified by:
get in interface NodeSet
Specified by:
get in class AbstractNodeSet
Parameters:
p -

isEmpty

public boolean isEmpty()
Description copied from interface: Sequence
Returns whether the sequence is empty or not.

Specified by:

Returns whether the sequence has just one item or not.

Specified by:
hasOne in interface Sequence
Specified by:
hasOne in class AbstractSequence

itemAt

public Item itemAt(int pos)
Description copied from interface: Sequence
Returns the item located at the specified position within this sequence. Items are counted beginning at 0.

Specified by:
itemAt in interface Sequence
Specified by:
