Constructor Detail

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 empty

nodeTest - : 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 interface LookaheadIterator<NodeInfo>

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 interface AxisIterator

Specified by:

next in interface SequenceIterator<NodeInfo>

Specified by:

next in interface UnfailingIterator<NodeInfo>

Returns:

the next Item. If there are no more items, return null.

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.
