AttributeAxisIterator
AttributeAxisIterator(ElementImpl node, java.util.function.Predicate<? super NodeInfo> 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

Method Detail
-
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 interfaceLookaheadIterator
- Returns:
- true if there are more items in the sequence
-
next
public NodeInfo next()
Get the next node in the iteration, or null if there are no more.- Specified by:
next
in interfaceAxisIterator
- Specified by:
next
in interfaceSequenceIterator
- Specified by:
next
in interfaceUnfailingIterator
- Returns:
- the next Item. If there are no more items, return null.
-
getProperties
public java.util.EnumSet<SequenceIterator.Property> getProperties()
Get properties of this iterator, as a bit-significant integer.- Specified by:
getProperties
in interfaceSequenceIterator
- Returns:
- the properties of this iterator. This will be some combination of
properties such as
SequenceIterator.Property.GROUNDED
,SequenceIterator.Property.LAST_POSITION_FINDER
, andSequenceIterator.Property.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.
