Constructor Detail

AttributeEnumeration

public AttributeEnumeration(NodeInfo node,
                            NodeTest nodeTest)
                     throws org.xml.sax.SAXException
Constructor
Parameters:
node: - the element whose attributes are required. This may be any type of node, but if it is not an element the enumeration will be empty
nodeType: - the type of node required. This may be any type of node, but if it is not an attribute the enumeration will be empty
nameTest: - condition to be applied to the names of the attributes selected
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 NodeEnumeration
Following copied from interface: com.icl.saxon.expr.NodeEnumeration
Returns:
true if there are more nodes

nextElement

public NodeInfo nextElement()
                     throws org.xml.sax.SAXException
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 NodeEnumeration
Following copied from interface: com.icl.saxon.expr.NodeEnumeration
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.expr.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.expr.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
