Class PrecedingEnumeration
java.lang.Object
|
+--com.icl.saxon.tinytree.PrecedingEnumeration
- All Implemented Interfaces:
- AxisEnumeration, LastPositionFinder, NodeEnumeration
- final class PrecedingEnumeration
- extends java.lang.Object
- implements AxisEnumeration
Enumerate all the nodes on the preceding axis from a given start node.
The calling code ensures that the start node is not a root, attribute,
or namespace node. As well as the standard XPath preceding axis, this
class also implements a Saxon-specific "preceding-or-ancestor" axis
which returns ancestor nodes as well as preceding nodes. This is used
when performing xsl:number level="any".
Method Summary |

hasMoreElements
public 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
- Following copied from interface:
com.icl.saxon.om.AxisEnumeration
- Returns:
- true if there are more nodes
nextElement
public 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
- Following copied from interface:
com.icl.saxon.om.AxisEnumeration
- Returns:
- the next NodeInfo
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
- Following copied from interface:
com.icl.saxon.om.NodeEnumeration
- Returns:
- true if the nodes are guaranteed to be in document order.
isReverseSorted
public 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
- Following copied from interface:
com.icl.saxon.om.NodeEnumeration
- 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
getLastPosition
public int getLastPosition()
- Get the last position, that is the number of nodes in the enumeration
- Specified by:
getLastPosition
in interface AxisEnumeration
