所有已实现的接口:

Serializable, org.apache.flink.api.common.io.CheckpointableInputFormat<org.apache.flink.core.fs.FileInputSplit,Long>, org.apache.flink.api.common.io.InputFormat<OT,org.apache.flink.core.fs.FileInputSplit>, org.apache.flink.core.io.InputSplitSource<org.apache.flink.core.fs.FileInputSplit>

@PublicEvolving
public class PrimitiveInputFormat<OT>
extends org.apache.flink.api.common.io.DelimitedInputFormat<OT>

An input format that reads single field primitive data from a given file. The difference between this and CsvInputFormat is that it won't go through Tuple1.
