public class DocumentTypeImpl

extends NodeContainer

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.

Constructor Detail

DocumentTypeImpl

public DocumentTypeImpl(DocumentImpl ownerDocument,
                        java.lang.String name)

Factory method for creating a document type node.

DocumentTypeImpl

public DocumentTypeImpl(DocumentImpl ownerDocument,
                        java.lang.String qualifiedName,
                        java.lang.String publicID,
                        java.lang.String systemID)

Factory method for creating a document type node.

Method Detail

getPublicId

public java.lang.String getPublicId()

Introduced in DOM Level 2.

Return the public identifier of this Document type.

Specified by:

getPublicId in interface DocumentType

Since:

WD-DOM-Level-2-19990923

getSystemId

public java.lang.String getSystemId()

Introduced in DOM Level 2.

Return the system identifier of this Document type.

Specified by:

getSystemId in interface DocumentType

Since:

WD-DOM-Level-2-19990923

setInternalSubset

public void setInternalSubset(java.lang.String internalSubset)

NON-DOM.

Set the internalSubset given as a string.

getInternalSubset

public java.lang.String getInternalSubset()

Introduced in DOM Level 2.

Return the internalSubset given as a string.

Specified by:

getInternalSubset in interface 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.

Overrides:

getNodeType in class NodeImpl

setNodeValue

public void setNodeValue(java.lang.String value)
                  throws DOMException

DocumentTypes never have a nodeValue.

Overrides:

setNodeValue in class NodeImpl

Throws:

DOMException(NO_MODIFICATION_ALLOWED_ERR) -

cloneNode

public Node cloneNode(boolean deep)

Clones the node.

Overrides:

cloneNode in class NodeContainer

Tags copied from 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.

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 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 NodeContainer

See Also:

NodeImpl.setReadOnly(boolean, boolean)

getElements

public NamedNodeMap getElements()

NON-DOM: Access the collection of ElementDefinitions.

ElementDefinitionImpl
