Method Details
-
moveNext
public boolean moveNext()Move to the next node, without returning it. Returns true if there is a next node, false if the end of the sequence has been reached. After calling this method, the current node may be retrieved using the current() function.- Specified by:
moveNext
in interfaceAxisIterator
-
iterateAxis
Return an iterator over an axis, starting at the current node.- Specified by:
iterateAxis
in interfaceAxisIterator
- Parameters:
axis
- the axis to iterate over, using a constant such asAxis.CHILD
test
- a predicate to apply to the nodes before returning them.- Throws:
NullPointerException
- if there is no current node
-
atomize
Return the atomized value of the current node.- Specified by:
atomize
in interfaceAxisIterator
- Returns:
- the atomized value.
- Throws:
NullPointerException
- if there is no current nodeXPathException
-
getStringValue
Return the string value of the current node.- Specified by:
getStringValue
in interfaceAxisIterator
- Returns:
- the string value, as an instance of CharSequence.
- Throws:
NullPointerException
- if there is no current node
-
getAnother
Get another iterator over the same items- Specified by:
getAnother
in interfaceSequenceIterator
- Specified by:
getAnother
in interfaceUnfailingIterator
- Overrides:
getAnother
in classArrayIterator
- Returns:
- a new ArrayIterator
-
getReverseIterator
Get an iterator that processes the same items in reverse order- Specified by:
getReverseIterator
in interfaceReversibleIterator
- Overrides:
getReverseIterator
in classArrayIterator
- Returns:
- a new ArrayIterator
