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.- 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 emptynodeType
- : the type of node required. This may be any type of node, but if it is not an attribute the enumeration will be emptynameTest
- : 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 interfaceAxisEnumeration
- Specified by:
hasMoreElements
in interfaceNodeEnumeration
- 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 interfaceAxisEnumeration
- Specified by:
nextElement
in interfaceNodeEnumeration
- 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 interfaceNodeEnumeration
- 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 interfaceNodeEnumeration
- 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 interfaceNodeEnumeration
-
getLastPosition
public int getLastPosition()
Get the last position, that is the number of nodes in the enumeration- Specified by:
getLastPosition
in interfaceAxisEnumeration
- Specified by:
getLastPosition
in interfaceLastPositionFinder
