Examples of org.apache.avro.io.ResolvingDecoder.drain()

org.apache.avro.io.ResolvingDecoder.drain()

Consume any more data that has been written by the writer but not needed by the reader so that the the underlying decoder is in proper shape for the next record. This situation happens when, for example, the writer writes a record with two fields and the reader needs only the first field. This function should be called after completely decoding an object but before next object can be decoded from the same underlying decoder either directly or through another resolving decoder. If the same resolving decoder is used for the next object as well, calling this method is optional; the state of this resolving decoder ensures that any leftover portions are consumed before the next object is decoded. @throws IOException
