Class DocumentTypeImpl

  • All Implemented Interfaces:
    Serializable, Cloneable, DocumentType, EventTarget, Node, NodeList
    Direct Known Subclasses:
    DeferredDocumentTypeImpl

    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.

    Since:
    PR-DOM-Level-1-19980818.

        Description copied from class: NodeImpl
        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: /** This attribute returns the text content of this node and its descendants.

      • isEqualNode

        public boolean isEqualNode​(Node arg)
        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.
      • getNodeNumber

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

        public void setReadOnly​(boolean readOnly,
                                boolean deep)
        NON-DOM: Subclassed to flip the entities' and notations' readonly switch as well.
        Overrides:
        setReadOnly in class ParentNode
        Parameters:
        readOnly - True or false as desired.
        deep - If true, children are also toggled. Note that this will not change the state of an EntityReference or its children, which are always read-only.

      • setUserData

        public Object setUserData​(String key,

        Description copied from class: NodeImpl
        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)
        Description copied from class: NodeImpl
        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.
