AttributeEnumeration
public AttributeEnumeration(NodeImpl node,
NodeTest nodeTest)
- 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 emptynodeTest:
- condition to be applied to the names of the attributes selected
hasNext
public boolean hasNext()
- 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:
hasNext
in interface LookaheadIterator
- Returns:
- true if there are more items in the sequence
next
public Item next()
- Get the next node in the iteration, or null if there are no more.
- Specified by:
next
in interface AxisIterator
- Specified by:
next
in interface SequenceIterator
- Returns:
- the next Item. If there are no more nodes, return null.
getAnother
public SequenceIterator getAnother()
- Get another enumeration of the same nodes
- Specified by:
getAnother
in interface AxisIterator
- Specified by:
getAnother
in interface SequenceIterator
- Returns:
- a new iterator over the same sequence
getProperties
public int getProperties()
- Get properties of this iterator, as a bit-significant integer.
- Specified by:
getProperties
in interface SequenceIterator
- Overrides:
getProperties
in class AxisIteratorImpl
- Returns:
- the properties of this iterator. This will be some combination of
properties such as
GROUNDED
, LAST_POSITION_FINDER
,
and LOOKAHEAD
. It is always
acceptable to return the value zero, indicating that there are no known special properties.
It is acceptable for the properties of the iterator to change depending on its state.
