Examples of org.codehaus.stax2.ri.Stax2EventReaderImpl

org.codehaus.stax2.ri.typed.ValueEncoderFactory
Almost complete implementation of {@link XMLEventReader2}, built on top of a generic {@link XMLStreamReader} implementation (using aggregation).Designed to be used by concrete Stax2 implementations to provide full Event API implementation with minimal effort.
Since there is not much to optimize at this level (API and underlying stream reader pretty much define functionality and optimizations that can be done), implementation is fairly straight forward, with not many surprises.
Implementation notes: the trickiest things to implement are:
- Peek() functionality! Geez, why did that have to be part of StAX specs???!
- Adding START_DOCUMENT event that cursor API does not return explicitly.
