CsvRowDataDeserializationSchema (Flink : Formats : Csv 2.0.0 API)

java.lang.Object
- org.apache.flink.formats.csv.CsvRowDataDeserializationSchema

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.serialization.DeserializationSchema<org.apache.flink.table.data.RowData>, org.apache.flink.api.java.typeutils.ResultTypeQueryable<org.apache.flink.table.data.RowData>
```
@Internal
public final class CsvRowDataDeserializationSchema
extends Object
implements org.apache.flink.api.common.serialization.DeserializationSchema<org.apache.flink.table.data.RowData>
```
Deserialization schema from CSV to Flink Table & SQL internal data structures.
Deserializes a byte[] message as a JsonNode and converts it to RowData.
Failure during deserialization are forwarded as wrapped IOExceptions.
