Examples of org.apache.avro.io.DecoderFactory$DefaultDecoderFactory

org.apache.avro.io.DecoderFactory
A factory for creating and configuring {@link Decoder}s.
Factories are thread-safe, and are generally cached by applications for performance reasons. Multiple instances are only required if multiple concurrent configurations are needed. @see Decoder
