Class Parser

java.lang.Object
  net.aethersanctum.curlyml.Parser

public class Parser
extends java.lang.Object

The purpose of the Parser is to generate a stream of events to be handled by a ParseEventHandler. The Parser is dumb by design. It doesn't know about Documents. All it knows how to do is check syntax and create events for inteception by a ParseEventHandler (like, say a DocumentLoader, which knows how to create a Document from parse events).

Other kinds of ParseEventHandlers might just process a stream of events and produce another stream without any kind of intermediate in-memory Document model. (e.g. a translator to convert CurlyML into HTML).
