  - finish
```
public void finish()
            throws XMLException
```
    Description copied from class: ComponentReader
    
    Called to signal an end of unmarshalling. This method should be overridden to perform any necessary clean up by an unmarshaller
    
    Overrides:
    
    finish in class ComponentReader
    
    Throws:
    
    XMLException
  - startElement
```
public void startElement(java.lang.String name,
                         java.lang.String namespace,
                         AttributeSet atts,

```
    Signals the start of an element with the given name.
    
    Overrides:
    
    startElement in class ComponentReader

    name - the NCName of the element. It is an error if the name is a QName (ie. contains a prefix).
    
    namespace - the namespace of the element. This may be null. Note: A null namespace is not the same as the default namespace unless the default namespace is also null.
    
    atts - the AttributeSet containing the attributes associated with the element.

    Overrides:
    
    endElement in class ComponentReader
