Class DOM2DTMdefaultNamespaceDeclarationNode

java.lang.Object
org.apache.xml.dtm.ref.dom2dtm.DOM2DTMdefaultNamespaceDeclarationNode
All Implemented Interfaces:
Attr, Node, TypeInfo

public class DOM2DTMdefaultNamespaceDeclarationNode extends Object implements Attr, TypeInfo
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.

      Specified by:
      setUserData in interface Node
      Parameters:

      Specified by:
      getUserData in interface Node
      Parameters:
      key - The key the object is associated to.
      Returns:
      Returns the DOMObject associated to the given key on this node, or null if there was none.
      Since:

    • getFeature

      public Object getFeature(String feature, String version)
      This method returns a specialized object which implements the specialized APIs of the specified feature and version. The specialized object may also be obtained by using binding-specific casting methods but is not necessarily expected to, as discussed in Mixed DOM implementations.
      Specified by:
      getFeature in interface Node
      Parameters:
      feature - The name of the feature requested (case-insensitive).
      version - This is the version number of the feature to test. If the version is null or the empty string, supporting any version of the feature will cause the method to return an object that supports at least one version of the feature.
      Returns:
      Returns an object which implements the specialized APIs of the specified feature and version, if any, or null if there is no object which implements interfaces associated with that feature. If the DOMObject returned by this method implements the Node interface, it must delegate to the primary core Node and not return results inconsistent with the primary core Node such as attributes, childNodes, etc.

      DOM Level 3
    • isEqualNode

      public boolean isEqualNode(Node arg)
      Tests whether two nodes are equal.
      This method tests for equality of nodes, not sameness (i.e., whether the two nodes are references to the same object) which can be tested with Node.isSameNode. All nodes that are the same will also be equal, though the reverse may not be true.
      Two nodes are equal if and only if the following conditions are satisfied: The two nodes are of the same type.The following string attributes are equal: nodeName, localName, namespaceURI, prefix, nodeValue , baseURI. This is: they are both null, or they have the same length and are character for character identical. The attributes NamedNodeMaps are equal. This is: they are both null, or they have the same length and for each node that exists in one map there is a node that exists in the other map and is equal, although not necessarily at the same index.The childNodes NodeLists are equal. This is: they are both null, or they have the same length and contain equal nodes at the same index. This is true for Attr nodes as for any other type of node. Note that normalization can affect equality; to avoid this, nodes should be normalized before being compared.
      For two DocumentType nodes to be equal, the following conditions must also be satisfied: The following string attributes are equal: publicId, systemId, internalSubset.The entities NamedNodeMaps are equal.The notations NamedNodeMaps are equal.
      On the other hand, the following do not affect equality: the ownerDocument attribute, the specified attribute for Attr nodes, the isWhitespaceInElementContent attribute for Text nodes, as well as any user data or event listeners registered on the nodes.
      Specified by:
      isEqualNode in interface Node
      Parameters:
      arg - The node to compare equality with.
      deep - If true, recursively compare the subtrees; if false, compare only the nodes themselves (and its attributes, if it is an Element).
      Returns:
      If the nodes, and possibly subtrees are equal, true otherwise false.

      DOM Level 3
    • lookupNamespaceURI

      public String lookupNamespaceURI(String specifiedPrefix)
      DOM Level 3 - Experimental: Look up the namespace URI associated to the given prefix, starting from this node. Use lookupNamespaceURI(null) to lookup the default namespace
      Specified by:
      lookupNamespaceURI in interface Node
      Parameters:
      namespaceURI -
      Returns:
      th URI for the namespace
      Since:
      DOM Level 3
    • isDefaultNamespace

      public boolean isDefaultNamespace(String namespaceURI)
      DOM Level 3: Experimental This method checks if the specified namespaceURI is the default namespace or not.
      Specified by:
      isDefaultNamespace in interface Node
      Parameters:
      namespaceURI - The namespace URI to look for.
      Returns:
      true if the specified namespaceURI is the default namespace, false otherwise.
      Since:
      DOM Level 3
    • lookupPrefix

      public String lookupPrefix(String namespaceURI)
      DOM Level 3 - Experimental: Look up the prefix associated to the given namespace URI, starting from this node.
      Specified by:
      lookupPrefix in interface Node
      Parameters:
      namespaceURI -
      Returns:
      the prefix for the namespace
    • isSameNode

      public boolean isSameNode(Node other)
      Returns whether this node is the same node as the given one.
      This method provides a way to determine whether two Node references returned by the implementation reference the same object. When two Node references are references to the same object, even if through a proxy, the references may be used completely interchangably, such that all attributes have the same values and calling the same DOM method on either reference always has exactly the same effect.
      Specified by:
      isSameNode in interface Node
      Parameters:
      other - The node to test against.
      Returns:
      Returns true if the nodes are the same, false otherwise.

      DOM Level 3
    • setTextContent

      public void setTextContent(String textContent) throws DOMException
      This attribute returns the text content of this node and its descendants. When it is defined to be null, setting it has no effect. When set, any possible children this node may have are removed and replaced by a single Text node containing the string this attribute is set to. On getting, no serialization is performed, the returned string does not contain any markup. No whitespace normalization is performed, the returned string does not contain the element content whitespaces . Similarly, on setting, no parsing is performed either, the input string is taken as pure textual content.
      The string returned is made of the text content of this node depending on its type, as defined below:
      Node type Content
      ELEMENT_NODE, ENTITY_NODE, ENTITY_REFERENCE_NODE, DOCUMENT_FRAGMENT_NODE concatenation of the textContent attribute value of every child node, excluding COMMENT_NODE and PROCESSING_INSTRUCTION_NODE nodes
      ATTRIBUTE_NODE, TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE, PROCESSING_INSTRUCTION_NODE nodeValue
      DOCUMENT_NODE, DOCUMENT_TYPE_NODE, NOTATION_NODE null

    • getBaseURI

      public String getBaseURI()
      The absolute base URI of this node or null if undefined. This value is computed according to . However, when the Document supports the feature "HTML" , the base URI is computed using first the value of the href attribute of the HTML BASE element if any, and the value of the documentURI attribute from the Document interface otherwise.
      When the node is an Element, a Document or a a ProcessingInstruction, this attribute represents the properties [base URI] defined in . When the node is a Notation, an Entity, or an EntityReference, this attribute represents the properties [declaration base URI] in the . How will this be affected by resolution of relative namespace URIs issue?It's not.Should this only be on Document, Element, ProcessingInstruction, Entity, and Notation nodes, according to the infoset? If not, what is it equal to on other nodes? Null? An empty string? I think it should be the parent's.No.Should this be read-only and computed or and actual read-write attribute?Read-only and computed (F2F 19 Jun 2000 and teleconference 30 May 2001).If the base HTML element is not yet attached to a document, does the insert change the Document.baseURI? Yes. (F2F 26 Sep 2001)
