类 FileRecords<T>

java.lang.Object

org.apache.flink.connector.file.src.impl.FileRecords<T>

所有已实现的接口:

org.apache.flink.connector.base.source.reader.RecordsWithSplitIds<RecordAndPosition<T>>

@Internal
public final class FileRecords<T>
extends Object
implements org.apache.flink.connector.base.source.reader.RecordsWithSplitIds<RecordAndPosition<T>>

A collection of records for one file split.

This is essentially a slim wrapper around the BulkFormat.RecordIterator that only adds information about the current split, or finished splits (to keep knowledge about current split IDs out of the reader formats).

方法概要
