Package org.apache.avro.io.parsing Description

Implementation of Avro schemas as LL(1) grammars.

See parser documentation for details on how this is achieved.

The classes in this package are used by ValidatingEncoder, ValidatingDecoder, ResolvingDecoder, JsonEncoder and JsonDecoder,

Unless one plans to generate a variation of the grammar or use a grammar, one not need to understand these classes.
