Class NotationImpl

java.lang.Object

org.openxml.dom.NodeImpl

org.openxml.dom.NotationImpl

All Implemented Interfaces:

Cloneable, Node, Notation

public final class NotationImpl
extends NodeImpl
implements Notation

Implements a notation. A notation node merely associates the notation's name with its system and/or public identifiers. The notation has no contents. This node is immutable.

Notes:

1. Node type is Node.NOTATION_NODE
2. Node does not support childern
3. Node does not have a value
4. Node only accessible from DocumentType

Constructor Detail

NotationImpl

public NotationImpl(String name,
                    String systemID,
                    String publicID)

Constructor requires owner document, notation name and all its attributes.

Parameters:

name - The entity name

systemID - The system identifier, if specified

publicID - The public identifier, if specified

Method Detail

getNodeType

public short getNodeType()

Description copied from class: NodeImpl

Abstract method must be implemented by each node class.

Specified by:

getNodeType in interface Node

Specified by:

getNodeType in class NodeImpl

See Also:

Node.getNodeType()

setNodeValue

public final void setNodeValue(String value)

Description copied from class: NodeImpl

Changes the value of the node. Not all node types support the notion of a value. If the value is not supported by a particular node type, it will throw an exception when calling this method. The following table specifies which node types support values:

 Element                Not supported
 Attr                   Supported
 Text                   Supported
 CDATASection           Supported
 EntityReference        Not supported
 Entity                 Not supported
 ProcessingInstruction  Supported
 Comment                Supported
 Document               Not supported
 DocumentType           Not supported
 DocumentFragment       Not supported
 Notation               Not supported
 

For most node types, if the value is set to null, NodeImpl.getNodeValue() will return an empty string instead.

Specified by:

setNodeValue in interface Node

Overrides:

setNodeValue in class NodeImpl

Parameters:

value - New value of node

getPublicId

public String getPublicId()

Specified by:

getPublicId in interface Notation

getSystemId

public String getSystemId()

Specified by:

getSystemId in interface Notation

equals

public boolean equals(Object other)

Description copied from class: NodeImpl

Returns true if this node and other are identical by content but not context. Test by content but not context adheres to the following:

• Both nodes must be of the same type, must have the same name and value (case sensitive) and for elements, the same tag name
• For elements, both must have identical attribute list, although attributes may be specified/unspecified and in different orders
• Both nodes must have no children, or must have the exact same sequence of children; children are tested for equality by calling NodeImpl.equals(java.lang.Object) on each pair
• However, both nodes may reside in different documents, belong to different parents, have different siblings, different read-only flags, etc.

It is guaranteed that the act of cloning a node will return a second node that will pass the test of equality.

Note that for large document roots, the equality operation can be very expensive.

Overrides:

equals in class NodeImpl

Parameters:

other - The other node to test for equality

Returns:

True if both nodes are equal based on their content but not their context

clone

public final Object clone()

Overrides:

clone in class Object

cloneNode

public final Node cloneNode(boolean deep)

Specified by:

cloneNode in interface Node

toString

public String toString()

Overrides:

toString in class Object

cloneInto

protected void cloneInto(NodeImpl into,
                         boolean deep)

Description copied from class: NodeImpl

This clone method is called after a new node has been constructed to copy the contents of this node into the new one. It clones in contents but not in context, and guarantees that the cloned node will pass the equality test (see NodeImpl.equals(java.lang.Object)).

into must be a valid node of the exact same class as this one. deep is true if deep cloning (includes all children nodes) is to be performed. If deep is false, the clone might not pass the equality test.

Derived classes override and call this method to add per-class variable copying. This method is called by Node.cloneNode(boolean) and the default Object.clone() method.

Contents cloning duplicates the node's name and value, and its children. It does not duplicate it's context, that is, the node's parent or sibling. Initially a clone node has no parents or siblings. However, the node does belong to the same document, since all nodes must belong to some document. The cloned node is never read-only.

Overrides:

cloneInto in class NodeImpl

Parameters:

into - A node into which to duplicate this one

deep - True if deep cloning is required
