Constructor Details
-
AttributeEnumeration
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 Details
-
moveNext
public boolean moveNext()Move to the next node in the iteration.- Specified by:
moveNext
in interfaceAxisIterator
- Overrides:
moveNext
in classAxisIteratorImpl
- Returns:
- true if there is a next node, false if the end of the sequence has been reached
-
next
Get the next item in the sequence.- Returns:
- the next Item. If there are no more nodes, return null.
-
current
Get the current node in the sequence.- Specified by:
current
in interfaceAxisIterator
- Specified by:
current
in interfaceSequenceIterator
- Specified by:
current
in interfaceUnfailingIterator
- Overrides:
current
in classAxisIteratorImpl
- Returns:
- the node returned by the most recent call on next(), or the node on which we positioned using moveNext()
-
atomize
Return the atomized value of the current node.- Specified by:
atomize
in interfaceAxisIterator
- Overrides:
atomize
in classAxisIteratorImpl
- Returns:
- the atomized value.
- Throws:
NullPointerException
- if there is no current nodeXPathException
- if the current node cannot be atomized, for example because it is an element node with element-only content.
-
getStringValue
Return the string value of the current node.- Specified by:
getStringValue
in interfaceAxisIterator
- Overrides:
getStringValue
in classAxisIteratorImpl
- Returns:
- the string value, as an instance of CharSequence.
- Throws:
NullPointerException
- if there is no current node
-
getAnother
Get another iteration over the same nodes- Returns:
- a new iterator over the same sequence
