Class DocumentTypeImpl

All Implemented Interfaces:
Cloneable, DocumentType, EventTarget, Node, NodeList

public class DocumentTypeImpl extends ParentNode implements DocumentType
This class represents a Document Type declaraction in the document itself, not a Document Type Definition (DTD). An XML document may (or may not) have such a reference.

DocumentType is an Extended DOM feature, used in XML documents but not in HTML.

Note that Entities and Notations are no longer children of the DocumentType, but are parentless nodes hung only in their appropriate NamedNodeMaps.

This area is UNDERSPECIFIED IN REC-DOM-Level-1-19981001 Most notably, absolutely no provision was made for storing and using Element and Attribute information. Nor was the linkage between Entities and Entity References nailed down solidly.

    • cloneNode

      public Node cloneNode(boolean deep)
      Returns a duplicate of a given node. You can consider this a generic "copy constructor" for nodes. The newly returned object should be completely independent of the source object's subtree, so changes in one after the clone has been made will not affect the other.

      Note: since we never have any children deep is meaningless here, ParentNode overrides this behavior. Returns a duplicate of a given node. You can consider this a generic "copy constructor" for nodes. The newly returned object should be completely independent of the source object's subtree, so changes in one after the clone has been made will not affect the other.

You can consider this a generic "copy constructor" for nodes. The newly returned object should be completely independent of the source object's subtree, so changes in one after the clone has been made will not affect the other.

      Example: Cloning a Text node will copy both the node and the text it contains.

      Example: Cloning something that has children -- Element or Attr, for example -- will _not_ clone those children unless a "deep clone" has been requested. A shallow clone of an Attr node will yield an empty Attr of the same name.

      NOTE: Clones will always be read/write, even if the node being cloned is read-only, to permit applications using only the DOM API to obtain editable copies of locked portions of the tree. Clones the node.

    • getTextContent

      public String getTextContent() 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

    • 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. DOM Level 3 WD- Experimental. Override inherited behavior from NodeImpl to support deep equal. DOM Level 3 WD- Experimental. Override inherited behavior from ParentNodeImpl to support deep equal.
      Specified by:
      isEqualNode in interface Node
      Overrides:
      isEqualNode in class ParentNode
      Parameters:
      arg - The node to compare equality with.
      Returns:
      If the nodes, and possibly subtrees are equal, true otherwise false.
    • setOwnerDocument

      protected void setOwnerDocument(CoreDocumentImpl doc)
      NON-DOM set the ownerDocument of this node and its children NON-DOM set the ownerDocument of this node and its children
      Overrides:
      setOwnerDocument in class ParentNode
    • getNodeNumber

      protected int getNodeNumber()
      NON-DOM Get the number associated with this doctype.
      Overrides:
      getNodeNumber in class NodeImpl
      Returns:
      the node number
    • getName

      public String getName()
      Name of this document type. If we loaded from a DTD, this should be the name immediately following the DOCTYPE keyword.
      Specified by:
      getName in interface DocumentType
    • getEntities

      public NamedNodeMap getEntities()
      Access the collection of general Entities, both external and internal, defined in the DTD. For example, in:
         <!doctype example SYSTEM "ex.dtd" [
           <!ENTITY foo "foo">
           <!ENTITY bar "bar">
           <!ENTITY % baz "baz">
           ]>
       

      The Entities map includes foo and bar, but not baz. It is promised that only Nodes which are Entities will exist in this NamedNodeMap.

      For HTML, this will always be null.

      Note that "built in" entities such as & and < should be converted to their actual characters before being placed in the DOM's contained text, and should be converted back when the DOM is rendered as XML or HTML, and hence DO NOT appear here.

      Specified by:
      getEntities in interface DocumentType
    • getNotations

      public NamedNodeMap getNotations()
      Access the collection of Notations defined in the DTD. A notation declares, by name, the format of an XML unparsed entity or is used to formally declare a Processing Instruction target.
      Specified by:
      getNotations in interface DocumentType
    • getElements

      public NamedNodeMap getElements()
    • setUserData

      public Object setUserData(String key, Object data, UserDataHandler handler)
      Associate an object to a key on this node. The object can later be retrieved from this node by calling getUserData with the same key.
      Specified by:
      setUserData in interface Node
      Overrides:
      setUserData in class NodeImpl
      Parameters:
      key - The key to associate the object to.
      data - The object to associate to the given key, or null to remove any existing association to that key.
      handler - The handler to associate to that key, or null.
      Returns:
      Returns the DOMObject previously associated to the given key on this node, or null if there was none.
    • getUserData

      public Object getUserData(String key)
      Retrieves the object associated to a key on a this node. The object must first have been set to this node by calling setUserData with the same key.
      Specified by:
      getUserData in interface Node
      Overrides:
      getUserData in class NodeImpl
      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.
