## org.apache.xml.dtm.ref.dom2dtm
Class DOM2DTMdefaultNamespaceDeclarationNode

    java.lang.Object
      org.apache.xml.dtm.ref.dom2dtm.DOM2DTMdefaultNamespaceDeclarationNode

All Implemented Interfaces:
  Attr, Node

public class DOM2DTMdefaultNamespaceDeclarationNode
extends java.lang.Object
implements Attr

This is a kluge to let us shove a declaration for xml: into the DOM2DTM model. Basically, it creates a proxy node in DOM space to carry the additional information. This is _NOT_ a full DOM implementation, and shouldn't be one since it sits alongside the DOM rather than becoming part of the DOM model. (This used to be an internal class within DOM2DTM. Moved out because I need to perform an instanceof operation on it to support a temporary workaround in DTMManagerDefault.) %REVIEW% What if the DOM2DTM was built around a DocumentFragment and there isn't a single root element? I think this fails that case... %REVIEW% An alternative solution would be to create the node _only_ in DTM space, but given how DOM2DTM is currently written I think this is simplest.

Method Detail

### getNodeName

    public java.lang.String getNodeName()

  Description copied from interface: `Node`
  The name of this node, depending on its type; see the table above.

  Specified by:
    `getNodeName` in interface `Node`

### getName

    public java.lang.String getName()

  Description copied from interface: `Attr`
  Returns the name of this attribute.

  Specified by:
    `getName` in interface `Attr`

### getNamespaceURI

    public java.lang.String getNamespaceURI()

  Description copied from interface: `Node`
  The namespace URI of this node, or `null` if it is unspecified.
  This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time.
  For nodes of any type other than `ELEMENT_NODE` and `ATTRIBUTE_NODE` and nodes created with a DOM Level 1 method, such as `createElement` from the `Document` interface, this is always `null`.Per the Namespaces in XML Specification an attribute does not inherit its namespace from the element it is attached to. If an attribute is not explicitly given a namespace, it simply has no namespace.

  Specified by:
    `getNamespaceURI` in interface `Node`

### getPrefix

    public java.lang.String getPrefix()

  Description copied from interface: `Node`
  The namespace prefix of this node, or `null` if it is unspecified.
  Note that setting this attribute, when permitted, changes the `nodeName` attribute, which holds the qualified name, as well as the `tagName` and `name` attributes of the `Element` and `Attr` interfaces, when applicable.
  Note also that changing the prefix of an attribute that is known to have a default value, does not make a new attribute with the default value and the original prefix appear, since the `namespaceURI` and `localName` do not change.
  For nodes of any type other than `ELEMENT_NODE` and `ATTRIBUTE_NODE` and nodes created with a DOM Level 1 method, such as `createElement` from the `Document` interface, this is always `null`.

  Specified by:
    `getPrefix` in interface `Node`

### getLocalName

    public java.lang.String getLocalName()

  Description copied from interface: `Node`
  Returns the local part of the qualified name of this node.
  For nodes of any type other than `ELEMENT_NODE` and `ATTRIBUTE_NODE` and nodes created with a DOM Level 1 method, such as `createElement` from the `Document` interface, this is always `null`.

  Specified by:
    `getLocalName` in interface `Node`

### getNodeValue

    public java.lang.String getNodeValue()

  Description copied from interface: `Node`
  The value of this node, depending on its type; see the table above. When it is defined to be `null`, setting it has no effect.

  Specified by:
    `getNodeValue` in interface `Node`

### getValue

    public java.lang.String getValue()

  Description copied from interface: `Attr`
  On retrieval, the value of the attribute is returned as a string. Character and general entity references are replaced with their values. See also the method `getAttribute` on the `Element` interface.
  On setting, this creates a `Text` node with the unparsed contents of the string. I.e. any characters that an XML processor would recognize as markup are instead treated as literal text. See also the method `setAttribute` on the `Element` interface.

  Specified by:
    `getValue` in interface `Attr`

### getOwnerElement

    public Element getOwnerElement()

  Description copied from interface: `Attr`
  The `Element` node this attribute is attached to or `null` if this attribute is not in use.

  Specified by:
    `getOwnerElement` in interface `Attr`

### isSupported

    public boolean isSupported(java.lang.String feature,
                               java.lang.String version)

  Description copied from interface: `Node`
  Tests whether the DOM implementation implements a specific feature and that feature is supported by this node.

  Specified by:
    `isSupported` in interface `Node`
  Parameters:
    `feature` - The name of the feature to test. This is the same name which can be passed to the method `hasFeature` on `DOMImplementation`.
    `version` - This is the version number of the feature to test. In Level 2, version 1, this is the string "2.0". If the version is not specified, supporting any version of the feature will cause the method to return `true`.
  Returns:
    Returns `true` if the specified feature is supported on this node, `false` otherwise.

### hasChildNodes

    public boolean hasChildNodes()

  Description copied from interface: `Node`
  Returns whether this node has any children.

  Specified by:
    `hasChildNodes` in interface `Node`
  Returns:
    `true` if this node has any children, `false` otherwise.

### hasAttributes

    public boolean hasAttributes()

  Description copied from interface: `Node`
  Returns whether this node (if it is an element) has any attributes.

  Specified by:
    `hasAttributes` in interface `Node`
  Returns:
    `true` if this node has any attributes, `false` otherwise.

### getParentNode

    public Node getParentNode()

  Description copied from interface: `Node`
  The parent of this node. All nodes, except `Attr`, `Document`, `DocumentFragment`, `Entity`, and `Notation` may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, this is `null`.

  Specified by:
    `getParentNode` in interface `Node`

### getFirstChild

    public Node getFirstChild()

  Description copied from interface: `Node`
  The first child of this node. If there is no such node, this returns `null`.

  Specified by:
    `getFirstChild` in interface `Node`

### getLastChild

    public Node getLastChild()

  Description copied from interface: `Node`
  The last child of this node. If there is no such node, this returns `null`.

  Specified by:
    `getLastChild` in interface `Node`

### getPreviousSibling

    public Node getPreviousSibling()

  Description copied from interface: `Node`
  The node immediately preceding this node. If there is no such node, this returns `null`.

  Specified by:
    `getPreviousSibling` in interface `Node`

### getNextSibling

    public Node getNextSibling()

  Description copied from interface: `Node`
  The node immediately following this node. If there is no such node, this returns `null`.

  Specified by:
    `getNextSibling` in interface `Node`

### getSpecified

    public boolean getSpecified()

  Description copied from interface: `Attr`
  If this attribute was explicitly given a value in the original document, this is `true`; otherwise, it is `false`. Note that the implementation is in charge of this attribute, not the user. If the user changes the value of the attribute (even if it ends up having the same value as the default value) then the `specified` flag is automatically flipped to `true`. To re-specify the attribute as the default value from the DTD, the user must delete the attribute. The implementation will then make a new attribute available with `specified` set to `false` and the default value (if one exists).
  In summary: If the attribute has an assigned value in the document then `specified` is `true`, and the value is the assigned value.If the attribute has no assigned value in the document and has a default value in the DTD, then `specified` is `false`, and the value is the default value in the DTD.If the attribute has no assigned value in the document and has a value of #IMPLIED in the DTD, then the attribute does not appear in the structure model of the document.If the `ownerElement` attribute is `null` (i.e. because it was just created or was set to `null` by the various removal and cloning operations) `specified` is `true`.

  Specified by:
    `getSpecified` in interface `Attr`

### normalize

    public void normalize()

  Description copied from interface: `Node`
  Puts all `Text` nodes in the full depth of the sub-tree underneath this `Node`, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates `Text` nodes, i.e., there are neither adjacent `Text` nodes nor empty `Text` nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer lookups) that depend on a particular document tree structure are to be used.In cases where the document contains `CDATASections`, the normalize operation alone may not be sufficient, since XPointers do not differentiate between `Text` nodes and `CDATASection` nodes.

  Specified by:
    `normalize` in interface `Node`

### getChildNodes

    public NodeList getChildNodes()

  Description copied from interface: `Node`
  A `NodeList` that contains all children of this node. If there are no children, this is a `NodeList` containing no nodes.

    `getChildNodes` in interface `Node`

### getAttributes

    public NamedNodeMap getAttributes()

  Description copied from interface: `Node`
  A `NamedNodeMap` containing the attributes of this node (if it is an `Element`) or `null` otherwise.

### setNodeValue

    public void setNodeValue(java.lang.String value)

  Description copied from interface: `Node`
  The value of this node, depending on its type; see the table above. When it is defined to be `null`, setting it has no effect.

    `setNodeValue` in interface `Node`

### setValue

    public void setValue(java.lang.String value)

  Description copied from interface: `Attr`
  On retrieval, the value of the attribute is returned as a string. Character and general entity references are replaced with their values. See also the method `getAttribute` on the `Element` interface.
  On setting, this creates a `Text` node with the unparsed contents of the string. I.e. any characters that an XML processor would recognize as markup are instead treated as literal text. See also the method `setAttribute` on the `Element` interface.

  Specified by:
    `setValue` in interface `Attr`

### setPrefix

    public void setPrefix(java.lang.String value)

  Description copied from interface: `Node`
  The namespace prefix of this node, or `null` if it is unspecified.
  Note that setting this attribute, when permitted, changes the `nodeName` attribute, which holds the qualified name, as well as the `tagName` and `name` attributes of the `Element` and `Attr` interfaces, when applicable.
  Note also that changing the prefix of an attribute that is known to have a default value, does not make a new attribute with the default value and the original prefix appear, since the `namespaceURI` and `localName` do not change.
  For nodes of any type other than `ELEMENT_NODE` and `ATTRIBUTE_NODE` and nodes created with a DOM Level 1 method, such as `createElement` from the `Document` interface, this is always `null`.

  Specified by:
    `setPrefix` in interface `Node`

### insertBefore

    public Node insertBefore(Node a,
                             Node b)

  Description copied from interface: `Node`
  Inserts the node `newChild` before the existing child node `refChild`. If `refChild` is `null`, insert `newChild` at the end of the list of children.
  If `newChild` is a `DocumentFragment` object, all of its children are inserted, in the same order, before `refChild`. If the `newChild` is already in the tree, it is first removed.

  Specified by:
    `insertBefore` in interface `Node`
  Parameters:
    `a` - The node to insert.
    `b` - The reference node, i.e., the node before which the new node must be inserted.
  Returns:
    The node being inserted.

### replaceChild

    public Node replaceChild(Node a,
                             Node b)

  Description copied from interface: `Node`
  Replaces the child node `oldChild` with `newChild` in the list of children, and returns the `oldChild` node.
  If `newChild` is a `DocumentFragment` object, `oldChild` is replaced by all of the `DocumentFragment` children, which are inserted in the same order. If the `newChild` is already in the tree, it is first removed.

  Specified by:
    `replaceChild` in interface `Node`
  Parameters:
    `a` - The new node to put in the child list.
    `b` - The node being replaced in the list.
  Returns:
    The node replaced.

### appendChild

    public Node appendChild(Node a)

  Description copied from interface: `Node`
  Adds the node `newChild` to the end of the list of children of this node. If the `newChild` is already in the tree, it is first removed.

  Specified by:
    `appendChild` in interface `Node`
  Parameters:
    `a` - The node to add.If it is a `DocumentFragment` object, the entire contents of the document fragment are moved into the child list of this node
  Returns:
    The node added.

### removeChild

    public Node removeChild(Node a)

  Description copied from interface: `Node`
  Removes the child node indicated by `oldChild` from the list of children, and returns it.

  Specified by:
    `removeChild` in interface `Node`
  Parameters:
    `a` - The node being removed.
  Returns:
    The node removed.

### getOwnerDocument

    public Document getOwnerDocument()

  Description copied from interface: `Node`
  The `Document` object associated with this node. This is also the `Document` object used to create new nodes. When this node is a `Document` or a `DocumentType` which is not used with any `Document` yet, this is `null`.

  Specified by:
    `getOwnerDocument` in interface `Node`

### cloneNode

    public Node cloneNode(boolean deep)

  Description copied from interface: `Node`
  Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent; ( `parentNode` is `null`.).
  Cloning an `Element` copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but this method does not copy any text it contains unless it is a deep clone, since the text is contained in a child `Text` node. Cloning an `Attribute` directly, as opposed to be cloned as part of an `Element` cloning operation, returns a specified attribute ( `specified` is `true`). Cloning any other type of node simply returns a copy of this node.
  Note that cloning an immutable subtree results in a mutable copy, but the children of an `EntityReference` clone are readonly . In addition, clones of unspecified `Attr` nodes are specified. And, cloning `Document`, `DocumentType`, `Entity`, and `Notation` nodes is implementation dependent.

  Specified by:
    `cloneNode` in interface `Node`
  Parameters:
    `deep` - If `true`, recursively clone the subtree under the specified node; if `false`, clone only the node itself (and its attributes, if it is an `Element`).
  Returns:
    The duplicate node.

### getHandleOfNode

    public int getHandleOfNode()

  Non-DOM method, part of the temporary kluge %REVIEW% This would be a pruning problem, but since it will always be added to the root element and we prune on elements, we shouldn't have to worry.
