  +--com.icl.saxon.tinytree.AttributeEnumeration

All Implemented Interfaces:

AxisEnumeration, LastPositionFinder, NodeEnumeration

final class AttributeEnumeration

extends java.lang.Object

implements AxisEnumeration

AttributeEnumeration is an enumeration of all the attribute nodes of an Element.

Constructor Summary

protected

AttributeEnumeration(TinyDocumentImpl doc, int element, NodeTest nodeTest) Constructor.

Method Summary

int	getLastPosition() Get the last position, that is the number of nodes in the enumeration
boolean	hasMoreElements() Test if there are mode nodes still to come.
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.
boolean	isReverseSorted() Determine whether the nodes returned by this enumeration are known to be in reverse document order.
boolean	isSorted() Determine whether the nodes returned by this enumeration are known to be in document order
NodeInfo	nextElement() Get the next node in the enumeration.

Constructor Detail

AttributeEnumeration

protected AttributeEnumeration(TinyDocumentImpl doc,
                               int element,
                               NodeTest nodeTest)

Constructor. Note: this constructor will only be called if the relevant node is an element and if it has one or more attributes. Otherwise an EmptyEnumeration will be constructed instead.

Method Detail

hasMoreElements

public boolean hasMoreElements()

Test if there are mode nodes still to come. ("elements" is used here in the sense of the Java enumeration class, not in the XML sense)

Specified by:

hasMoreElements in interface AxisEnumeration

Returns:

true if there are more nodes

nextElement

public NodeInfo nextElement()

Get the next node in the enumeration. ("elements" is used here in the sense of the Java enumeration class, not in the XML sense)

Specified by:

nextElement in interface 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

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

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
