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 TinyTree

element: - the node number of the element whose attributes are required

nodeTest: - 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 interface SequenceIterator<NodeInfo>

Specified by:

next in interface AxisIterator

Specified by:

next in interface UnfailingIterator<NodeInfo>

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 interface AtomizedValueIterator<NodeInfo>

Returns:

the next atomic value

Throws:

XPathException - if a failure occurs reading or atomizing the next value

getProperties

public int getProperties()

Get properties of this iterator, as a bit-significant integer.

Specified by:

getProperties in interface SequenceIterator<NodeInfo>

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.
