Constructor Detail

FAttr

public FAttr(QNm n,
     byte[] v)

Default constructor.

Parameters:

n - name

v - value

FAttr

public FAttr(org.w3c.dom.Attr attr)

Constructor for DOM nodes. Originally provided by Erdal Karaca.

Parameters:

attr - DOM node

Method Detail

qname

public QNm qname()

Description copied from class: ANode

Returns the QName of the node. This function must only be called for elements, attributes and pi's.

Overrides:

qname in class ANode

Returns:

name

name

public byte[] name()

Description copied from class: ANode

Returns the name of the node, composed of an optional prefix and the local name. This function must only be called for element and attribute nodes. It is more efficient than calling ANode.qname(), as no QNm instance is created.

Overrides:

name in class ANode

Returns:

name

copy

public FNode copy()

Description copied from class: ANode

Returns a copy of the node.

Specified by:

copy in class ANode

Returns:

copy

serialize

public void serialize(Serializer ser)
               throws java.io.IOException

Description copied from class: Item

Serializes the item.

Specified by:

serialize in class ANode

Parameters:

ser - serializer

Throws:

java.io.IOException - I/O exception

plan

public void plan(Serializer ser)
          throws java.io.IOException

Description copied from class: ExprInfo

Serializes the expression tree.

Overrides:

plan in class Item

Parameters:

ser - serializer

Throws:

java.io.IOException - I/O exception

xdmInfo

public byte[] xdmInfo()

Description copied from class: Item

Returns meta data on the current item.

Overrides:

xdmInfo in class Item

Returns:

type string

toString

public java.lang.String toString()

Specified by:

toString in class ExprInfo
