Constructor Detail

AttributeEnumeration

AttributeEnumeration(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

moveNext

public boolean moveNext()

Move to the next node in the iteration.

Specified by:

moveNext in interface AxisIterator

Overrides:

moveNext in class AxisIteratorImpl

Returns:

true if there is a next node, false if the end of the sequence has been reached

next

public NodeInfo next()

Get the next item in the sequence.

Returns:

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

current

public NodeInfo current()

Get the current node in the sequence.

Specified by:

current in interface AxisIterator

Specified by:

current in interface SequenceIterator

Specified by:

current in interface UnfailingIterator

Overrides:

current in class AxisIteratorImpl

Returns:

the node returned by the most recent call on next(), or the node on which we positioned using moveNext()

atomize

public Value atomize()
              throws XPathException

Return the atomized value of the current node.

Specified by:

atomize in interface AxisIterator

Overrides:

atomize in class AxisIteratorImpl

Returns:

the atomized value.

Throws:

java.lang.NullPointerException - if there is no current node

XPathException - if the current node cannot be atomized, for example because it is an element node with element-only content.

getStringValue

public java.lang.CharSequence getStringValue()

Return the string value of the current node.

Specified by:

getStringValue in interface AxisIterator

Overrides:

getStringValue in class AxisIteratorImpl

Returns:

the string value, as an instance of CharSequence.

Throws:

java.lang.NullPointerException - if there is no current node

getAnother

public AxisIterator getAnother()

Get another iteration over the same nodes

Returns:

a new iterator over the same sequence
