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 SequenceIterator
- Specified by:
next
in interface UnfailingIterator
- Returns:
- the next item, or null if there are no more items. Once a call
on next() has returned null, no further calls should be made. The preferred
action for an iterator if subsequent calls on next() are made is to return
null again, and all implementations within Saxon follow this rule.
getAnother
public SequenceIterator getAnother()
- Get another enumeration of the same nodes
- Specified by:
getAnother
in interface SequenceIterator
- Specified by:
getAnother
in interface UnfailingIterator
- Returns:
- a SequenceIterator that iterates over the same items,
positioned before the first item
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
SequenceIterator.GROUNDED
, SequenceIterator.LAST_POSITION_FINDER
,
and SequenceIterator.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.
