TimestampedFileInputSplit

public TimestampedFileInputSplit(long modificationTime,
                                 int num,
                                 org.apache.flink.core.fs.Path file,
                                 long start,
                                 long length,
                                 String[] hosts)

Creates a TimestampedFileInputSplit based on the file modification time and the rest of the information of the FileInputSplit, as returned by the underlying filesystem.

参数:

modificationTime - the modification file of the file this split belongs to

num - the number of this input split

file - the file name

start - the position of the first byte in the file to process

length - the number of bytes in the file to process (-1 is flag for "read whole file")

hosts - the list of hosts containing the block, possibly null

方法详细资料

setSplitState

public void setSplitState(Serializable state)

Sets the state of the split. This information is used when restoring from a checkpoint and allows to resume reading the underlying file from the point we left off.

* This is applicable to FileInputFormats that implement the CheckpointableInputFormat interface.

指定者:

setSplitState 在接口中 TimestampedInputSplit

getSplitState

public Serializable getSplitState()

指定者:

getSplitState 在接口中 TimestampedInputSplit

返回:

the state of the split.

getModificationTime

public long getModificationTime()

指定者:

getModificationTime 在接口中 TimestampedInputSplit

返回:

The modification time of the file this split belongs to.

compareTo

public int compareTo(TimestampedInputSplit o)

指定者:

compareTo 在接口中 Comparable<TimestampedInputSplit>

equals

public boolean equals(Object o)

覆盖:

equals 在类中 org.apache.flink.core.fs.FileInputSplit

hashCode

public int hashCode()
