类 OggJsonDeserializationSchema

java.lang.Object

org.apache.flink.formats.json.ogg.OggJsonDeserializationSchema

所有已实现的接口:

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 OggJsonDeserializationSchema
extends Object
implements org.apache.flink.api.common.serialization.DeserializationSchema<org.apache.flink.table.data.RowData>

Deserialization schema from Ogg JSON to Flink Table/SQL internal data structure RowData. The deserialization schema knows Ogg's schema definition and can extract the database data and convert into RowData with RowKind.

Deserializes a byte[] message as a JSON object and reads the specified fields.

Failures during deserialization are forwarded as wrapped IOExceptions.
