public abstract class SimpleState
- extends State
base interface of the most of parsing states.
In this level of inheritance, contract is as follows.
- startElement() event is received by the parent state.
It usually creates a child state by this event.
- startSelf method of the child SimpleState is called.
derived classes should perform necessary things
by reading start tag information.
- Whenever startElement method is received by
SimpleState object, createChildState method is
called to create a child state.
Derived classes are responsible for providing
appropriate child state objects.
- Child state handles descendants. Usually, it finishes
parsing when it sees endElement.
- When endElement(
) event is received by this object,
it calls endSelf method and reverts to the parent state.
Derived classes are responsible for doing anything
necessary within endSelf method.
In other words, this state is only active for one hierarchy of XML elements
and derived classes are responsible for three abstract methods.

SimpleState
public SimpleState()
isGrammarElement
protected boolean isGrammarElement(StartTagInfo tag)
- checks if this element belongs to the grammar.
startElement
public void startElement(String namespaceURI,
String localName,
String qName,
Attributes atts)
createChildState
protected abstract State createChildState(StartTagInfo tag)
- creates appropriate child state object for this element
endElement
public final void endElement(String namespaceURI,
String localName,
String qName)
endDocument
public final void endDocument()
endSelf
protected void endSelf()
- this method is called in endElement method
when the state is about to be removed.
derived-class should perform any wrap-up job
