Class TypedDocument<E extends TypedElement<E,X>,X extends TypedExtension>

java.lang.Object

eu.bandm.tools.tdom.runtime.TypedNode<X>

eu.bandm.tools.tdom.runtime.TypedDocument<E,X>

Direct Known Subclasses:

Document, Document, Document, Document

public abstract class TypedDocument<E extends TypedElement<E,X>,X extends TypedExtension>
extends TypedNode<X>

Fundamental base class for all Elements which can serve as a "document element" / "root element". One(1) immediate subclass of this class with the name "Document" will be generated in each tdom model. Then for every element declaration (e.g. "EL") which is declared as "public" by a PI in the underlying DTD, a subclass of this class is generated called "Document_EL". This class will provide the factory methods for converting sources into complete document instances and other global methods. Since these rely on the generated classes, they cannot be found here, but only in the generated code. They will look aprox. like ...

     Document_EL (Element_EL) {..}
         // = bottom-up explicit constructor
     Document_EL (SAXEventStream,TypedExtension) {..}
         // = for parsing a complete document from the sax input
     Document_EL (org.w3c.dom.Document, Extension) {..}
         // = for converting one complete DOM model into a tdom model
     ElementDictionary<Element> createDictionary() {..}
         // = for linking all id and idref attributes
  

(Reminder: "Element" is the name of the generated class serving as common base class of all element classes.)

Constructor Detail

TypedDocument

protected TypedDocument(TypedDTD dtd)

Method Detail

getDTD

public final TypedDTD getDTD()

Returns the global DTD information compiled into this tdom model. This includes reflexive data about the generated base classes.

Returns:

the global DTD information compiled into this tdom model.

getEtherealContainer

public TypedEtherealContainer getEtherealContainer()

Gives access to the Comments and PIs after the opening tag and before the close tag.

Returns:

(never null) access to the Comments and PIs before the very first element's opening tag, and after its closing tag.

getTagIndex

protected int getTagIndex()

getRootUntyped

public TypedElement<E,X> getRootUntyped()

Returns the root element as an instance of TypedElement, so this method works for different tdom models.

encode

public void encode(java.io.OutputStream out,
                   X ext)
            throws java.io.IOException

Throws:

java.io.IOException

encode

public void encode(EncodingOutputStream out,
                   X ext)
            throws java.io.IOException

Description copied from class: TypedNode

Abstract fall-back method which MUST be overridden and always throws an Exception.

Specified by:

encode in class TypedNode<X extends TypedExtension>

Throws:

java.io.IOException

decode

public final void decode(java.io.InputStream in,
                         X ext)
                  throws java.io.IOException,
                         TdomContentException,
                         TdomAttributeException

Throws:

java.io.IOException

TdomContentException

TdomAttributeException

decode

protected abstract E decode(DecodingInputStream in,
                            X ext)
                     throws java.io.IOException,
                            TdomContentException,
                            TdomAttributeException

Throws:

java.io.IOException

TdomContentException

TdomAttributeException

start

public void start(org.xml.sax.ContentHandler contentHandler,
                  org.xml.sax.ext.LexicalHandler lexicalHandler)
           throws org.xml.sax.SAXException

Send the opening sax events to the two drains. These are the ContentHandler.startDocument() event, followed by the leading comments from getEtherealContainer().

Throws:

org.xml.sax.SAXException

end

public void end(org.xml.sax.ContentHandler contentHandler,
                org.xml.sax.ext.LexicalHandler lexicalHandler)
         throws org.xml.sax.SAXException

Send the closing sax events to the two drains. These are the trailing comments from getEtherealContainer(), followed by ContentHandler.endDocument().

Throws:

org.xml.sax.SAXException

createDictionary

public ElementDictionary<E,X> createDictionary()

Create a dictionary which maps all Elements with id fields to the id values, and vice versa. These Elements are identified by implementing Identifiable. The data are collected using ElementDictionary.addIfIdentifiable(TypedElement). See there for the exception conditions.

Throws:

HomonymousIdException - see ElementDictionary

encodeEthereals

protected void encodeEthereals(EncodingOutputStream s)

Writes out the comments and pis. Is called automatically when writing out a TypedDocument. (The decode part must be applied explicitly by the user.)

decodeEthereals

public void decodeEthereals(DecodingInputStream s)

Must be called explicitly by the user, after he/she has created the document object. (The invocation of the document creation method is via the generated "TypedDTD.createDocument_[XX](..)".)
