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
-
-
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, 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 AxisIterator getAnother()
Get another enumeration of the same nodes- Specified by:
getAnother
in interfaceAxisIterator
- Specified by:
getAnother
in interfaceSequenceIterator
- Specified by:
getAnother
in interfaceUnfailingIterator
- 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 interfaceSequenceIterator
- Overrides:
getProperties
in classAxisIteratorImpl
- Returns:
- the properties of this iterator. This will be some combination of
properties such as
SequenceIterator.GROUNDED
,SequenceIterator.LAST_POSITION_FINDER
, andSequenceIterator.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.
