Simple interface that processing additions can implement to be easily pluggable to main Jackson jr handler, JSON. Extensions typically provide things like custom readers (ValueReader) and writers (ValueWriter) (via ReaderWriterProvider), and modifers (ReaderWriterModifier) that allow customizing aspects of JSON reading and writing.
