NodeWrapper.AncestorEnumeration

public NodeWrapper.AncestorEnumeration(NodeWrapper start,
                                       boolean includeSelf)

Method Detail

advance

public void advance()

Specified by:

advance in class com.icl.saxon.jdom.NodeWrapper.BaseEnumeration

isSorted

public boolean isSorted()

Description copied from interface: NodeEnumeration

Determine whether the nodes returned by this enumeration are known to be in document order

Specified by:

isSorted in interface NodeEnumeration

Overrides:

isSorted in class com.icl.saxon.jdom.NodeWrapper.BaseEnumeration

Returns:

true if the nodes are guaranteed to be in document order.

isPeer

public boolean isPeer()

Description copied from interface: NodeEnumeration

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 class com.icl.saxon.jdom.NodeWrapper.BaseEnumeration

copy

public com.icl.saxon.jdom.NodeWrapper.BaseEnumeration copy()

Specified by:

copy in class com.icl.saxon.jdom.NodeWrapper.BaseEnumeration

hasMoreElements

public final boolean hasMoreElements()

Description copied from interface: AxisEnumeration

Determine whether there are more nodes to come.
(Note the term "Element" is used here in the sense of the standard Java Enumeration class, it has nothing to do with XML elements).

Specified by:

hasMoreElements in interface AxisEnumeration

Returns:

true if there are more nodes

nextElement

public final NodeInfo nextElement()

Description copied from interface: AxisEnumeration

Get the next node in sequence.
(Note the term "Element" is used here in the sense of the standard Java Enumeration class, it has nothing to do with XML elements).

Specified by:

nextElement in interface AxisEnumeration

Returns:

the next NodeInfo

getLastPosition

public final int getLastPosition()

Description copied from interface: AxisEnumeration

Get the last position

Specified by:

getLastPosition in interface AxisEnumeration

isReverseSorted

public final boolean isReverseSorted()

Description copied from interface: NodeEnumeration

Determine whether the nodes returned by this enumeration are known to be in reverse document order.

Specified by:

isReverseSorted in interface NodeEnumeration

Returns:

true if the nodes are guaranteed to be in document order.
