Constructor Detail

### ElementDecl

    public ElementDecl()

  Default constructor. Note that this constructor is used only during deserialization/decompression of this DOM node. In order to deserialize this node to construct the DOM node from the serialized/ compressed stream, it is required to create a handle of the object.

Method Detail

### getNodeType

    public short getNodeType()

  Gets a code representing the type of the underlying object
  Specified by:
    `getNodeType` in interface `Node`
  Overrides:
    `getNodeType` in class `XMLNode`
  Returns:
    type of the node

### getNodeName

    public java.lang.String getNodeName()

  Gets the name of this node, depending on its type
  Specified by:
    `getNodeName` in interface `Node`
  Overrides:
    `getNodeName` in class `XMLNode`
  Returns:
    Name of this node

### validateContent

    public boolean validateContent(Element e)

  Validates the content of a element node.
  Returns:
    True if valid, else false

### expectedElements

    public java.util.Vector expectedElements(Element e)

  Returns vector of element names that can be appended to the element.
  Parameters:
    `e` - Element
  Returns:
    Vector of names

### getAttrDecls

    public NamedNodeMap getAttrDecls()

  Gets an enumeration of attribute declarations
  Returns:
    An enumeration of attribute declarations

### findAttrDecl

    public final AttrDecl findAttrDecl(java.lang.String name)

  Gets an attribute declaration object or null if not found
  Parameters:
    `name` - Attribute declaration to find
  Returns:
    The `AttrDecl` object, or null, if it was not found

### getContentType

    public int getContentType()

  Returns content model of element
  Returns:
    The `type` of the element declaration.

### getContentElements

    public final java.util.Vector getContentElements()

  Returns Vector of elements that can be appended to this element
  Returns:
    The `Vector` containing the element names.

### getParseTree

    public final Node getParseTree()

  Returns the root node of Content Model Parse Tree. Node.getFirstChild() and Node.getLastChild() return the the parse tree branches. Node.getNodeType() and Node.getNodeName() return the the parse tree node type and name.
  Returns:
    The Node containing the Content Model parse tree root node.

### writeExternal

    public void writeExternal(java.io.ObjectOutput outArg)
                       throws java.io.IOException

  This method saves the state of the object by creating a binray compressed stream with information about this object.
  Specified by:
    `writeExternal` in interface `java.io.Externalizable`
  Overrides:
    `writeExternal` in class `XMLNode`
  Parameters:
    `outArg` - The ObjectOutput stream used to write the serialized/ compressed stream.
  Throws:
    `java.io.IOException` - is thrown when there is an exception while writing the serialized/compressed stream.

### readExternal

    public void readExternal(java.io.ObjectInput inArg)
                      throws java.io.IOException,
                             java.lang.ClassNotFoundException

  This method reads the information written in the compressed stream by writeExternal method and restores the object correspondingly.
  Specified by:
    `readExternal` in interface `java.io.Externalizable`
  Overrides:
    `readExternal` in class `XMLNode`
  Parameters:
    `inArg` - the ObjectInput used for reading the compressed stream
  Throws:
    `java.io.IOException` - is thrown when there is an error in reading the input stream.
    `java.lang.ClassNotFoundException` - is thrown when the class is not found
