# Package org.apache.avro.io.parsing

package org.apache.avro.io.parsing
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.
