Constructor Detail
-
AttributeIterator
AttributeIterator(TinyTree tree, 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:
tree
- : the containing TinyTreeelement
- : the node number of the element whose attributes are requirednodeTest
- : condition to be applied to the names of the attributes selected

Method Detail
-
next
public NodeInfo next()
Get the next item in the sequence.- Specified by:
next
in interfaceAxisIterator
- Specified by:
next
in interfaceSequenceIterator
- Specified by:
next
in interfaceUnfailingIterator
- Returns:
- the next Item. If there are no more nodes, return null.
-
nextAtomizedValue
public AtomicSequence nextAtomizedValue() throws XPathException
Deliver the atomic value that is next in the atomized result- Specified by:
nextAtomizedValue
in interfaceAtomizedValueIterator
- Returns:
- the next atomic value
- Throws:
XPathException
- if a failure occurs reading or atomizing the next value
-
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.
