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:
out - 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:
in - the ObjectInput stream 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
