Constructor Details

CassandraOutgoingFile

public CassandraOutgoingFile(StreamOperation operation,
 Ref<SSTableReader> ref,
 List<SSTableReader.PartitionPositionBounds> sections,
 List<Range<Token>> normalizedRanges,
 long estimatedKeys)

Method Details

fromStream

public static CassandraOutgoingFile fromStream(OutgoingStream stream)

getRef

public Ref<SSTableReader> getRef()

getName

public String getName()

Specified by:

getName in interface OutgoingStream

getEstimatedSize

public long getEstimatedSize()

Specified by:

getEstimatedSize in interface OutgoingStream

Returns:

estimated file size to be streamed. This should only be used for metrics, because concurrent stats metadata update and index redistribution will change file sizes.

getTableId

public TableId getTableId()

Specified by:

getTableId in interface OutgoingStream

getNumFiles

public int getNumFiles()

Specified by:

getNumFiles in interface OutgoingStream

getRepairedAt

public long getRepairedAt()

Specified by:

getRepairedAt in interface OutgoingStream

getPendingRepair

public TimeUUID getPendingRepair()

Specified by:

getPendingRepair in interface OutgoingStream

write

public void write(StreamSession session,
 StreamingDataOutputPlus out,
 int version)
           throws IOException

Description copied from interface: OutgoingStream

Write the streams data into the socket

Specified by:

write in interface OutgoingStream

Throws:

IOException

computeShouldStreamEntireSSTables

public boolean computeShouldStreamEntireSSTables()

contained

public boolean contained(List<SSTableReader.PartitionPositionBounds> sections,
 SSTableReader sstable)

finish

public void finish()

Description copied from interface: OutgoingStream

Release any resources held by the stream

Specified by:

finish in interface OutgoingStream

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
