public class DocumentTypeImpl
extends ParentNode
implements org.w3c.dom.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.

  Return the internalSubset given as a string.

  Specified by:
    `getInternalSubset` in interface `org.w3c.dom.DocumentType`
  Since:
    WD-DOM-Level-2-19990923

### getNodeType

    public short getNodeType()

  A short integer indicating what type of node this is. The named constants for this value are defined in the org.w3c.dom.Node interface.
  Specified by:
    `getNodeType` in interface `org.w3c.dom.Node`
  Overrides:
    `getNodeType` in class `NodeImpl`

### getNodeName

    public java.lang.String getNodeName()

  Returns the document type name
  Specified by:
    `getNodeName` in interface `org.w3c.dom.Node`
  Overrides:
    `getNodeName` in class `NodeImpl`

### cloneNode

    public org.w3c.dom.Node cloneNode(boolean deep)

  Clones the node.
  Specified by:
    `cloneNode` in interface `org.w3c.dom.Node`
  Overrides:
    `cloneNode` in class `ParentNode`
  Following copied from class: `org.apache.xerces.dom.ChildNode`
  See Also:
    `

    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.

    `

### getTextContent

    public java.lang.String getTextContent()
                                    throws org.w3c.dom.DOMException

  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:

  Node type | Content
  --- | ---
  /** 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

  Overrides:
    `getTextContent` in class `ParentNode`
  Following copied from class: `org.apache.xerces.dom.NodeImpl`
  Throws:
    `org.w3c.dom.DOMException` - NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.
    `org.w3c.dom.DOMException` - DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a `DOMString` variable on the implementation platform.

### setTextContent

    public void setTextContent(java.lang.String textContent)
                        throws org.w3c.dom.DOMException

  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.

  Overrides:
    `setTextContent` in class `ParentNode`
  Following copied from class: `org.apache.xerces.dom.NodeImpl`
  Throws:
    `org.w3c.dom.DOMException` - NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.
    `org.w3c.dom.DOMException` - DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a `DOMString` variable on the implementation platform.

### getNodeNumber

    protected int getNodeNumber()

  NON-DOM Get the number associated with this doctype.
  Overrides:
    `getNodeNumber` in class `NodeImpl`

### getName

    public java.lang.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 `org.w3c.dom.DocumentType`

### getEntities

    public org.w3c.dom.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 `org.w3c.dom.DocumentType`

### getNotations

    public org.w3c.dom.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 `org.w3c.dom.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`
  See Also:
    `NodeImpl.setReadOnly(boolean, boolean)`

### getElements

    public org.w3c.dom.NamedNodeMap getElements()

  NON-DOM: Access the collection of ElementDefinitions.
  See Also:
    `ElementDefinitionImpl`
