AbstractNamespace
is an abstract base class for
tree implementors to use for implementation inheritence.

Modifier and Type | Method and Description |
---|---|
void |
accept(Visitor visitor)
accept is the method used in the Visitor Pattern. |
String |
asXML()
asXML returns the textual XML representation of this
node. |
protected Node |
createXPathResult(Element parent) |
Object |
getData()
Accesses the data of this attribute which may implement data typing
bindings such as XML Schema or
Java Bean bindings or will return the same value as
Node.getText() |
String |
getName()
getName returns the name of this node. |
Namespace |
getNamespace()
Returns the
Namespace of this element if one exists
otherwise null is returned returned. |
String |
getNamespacePrefix()
Returns the namespace prefix of this element if one exists
otherwise an empty
String is returned. |
String |
getNamespaceURI()
Returns the URI mapped to the namespace of this element
if one exists otherwise an empty
String is returned. |
short |
getNodeType()
Returns the code according to the type of node.
|
String |
getPath(Element context)
Returns the relative XPath expression which will return a node set
containing the given node such as a/b/@c.
|
String |
getQualifiedName()
Returns the fully qualified name of this element.
|
String |
getText()
Returns the text of this node.
|
String |
getUniquePath(Element context)
Returns the relative unique XPath expression from the given context
which will return a nodeset
of one node which is the current node.
|
void |
setData(Object data)
Sets the data value of this attribute if this element supports data
binding or calls
Node.setText(java.lang.String) if it doesn't |
void |
setNamespace(Namespace namespace)
Sets the
Namespace of this element or if this element
is read only then an UnsupportedOperationException
is thrown. |
void |
setText(String text)
Sets the text data of this node or this method will
throw an
UnsupportedOperationException if it is
read-only. |
void |
setValue(String value)
Sets the value of this attribute or this method will
throw an
UnsupportedOperationException if it is
read-only. |
String |
toString() |
void |
write(Writer writer)
write writes this node as the default XML
notation for this node. |

Node
asXML
returns the textual XML representation of this
node.
public void write(Writer writer) throws IOException
Node
write
writes this node as the default XML
notation for this node. If you wish to control the XML output
(such as for pretty printing, changing the indentation policy etc.)
then please use XMLWriter
or its derivations.

public void accept(Visitor visitor)
Node
accept
is the method used in the Visitor Pattern.
public Namespace getNamespace()
Attribute
Returns the Namespace
of this element if one exists
otherwise null is returned returned.
getNamespace
in interface Attribute
Namespace
associated with this nodepublic String getName()
Node
getName
returns the name of this node.
This is the XML local name of the element, attribute, entity or
processing instruction.
For CDATA and Text nodes this method will return null.

in class AbstractNode
public String getNamespacePrefix()
Attribute
Returns the namespace prefix of this element if one exists
otherwise an empty String
is returned.
getNamespacePrefix
in interface Attribute
Namespace
of this element
or an empty String
public String getNamespaceURI()
Attribute
Returns the URI mapped to the namespace of this element
if one exists otherwise an empty String
is returned.
getNamespaceURI
in interface Attribute
Namespace
of this element
or an empty String
public String getQualifiedName()
Attribute
Returns the fully qualified name of this element.
This will be the same as the value returned from Node.getName()
if this element has no namespace attached to this element or an
expression of the form
getNamespacePrefix() + ":" + getName()will be returned.
getQualifiedName
in interface Attribute
public String getPath(Element context)
Node
Returns the relative XPath expression which will return a node set containing the given node such as a/b/@c. No indexing will be used to restrict the path if multiple elements with the same name occur on the path.
getPath
in interface Node
context
- is the parent context from which the relative path should
start. If the context is null or the context is not an ancestor of
this node then the path will be absolute and start from the document and so
begin with the '/' character.public String getUniquePath(Element context)
Node
Returns the relative unique XPath expression from the given context which will return a nodeset of one node which is the current node. This method will use the XPath index operator to restrict the path if multiple elements with the same name occur on the path.
getUniquePath
in interface Node
context
- is the parent context from which the path should
start. If the context is null or the context is not an ancestor of
this node then the path will start from the document and so
