Method Detail

begin

public void begin()

Description copied from interface: SSTableFlushObserver

Called before writing any data to the sstable.

Specified by:

begin in interface SSTableFlushObserver

startPartition

public void startPartition(DecoratedKey key,
                           long curPosition)

Description copied from interface: SSTableFlushObserver

Called when a new partition in being written to the sstable, but before any cells are processed (see SSTableFlushObserver.nextUnfilteredCluster(Unfiltered)).

Specified by:

startPartition in interface SSTableFlushObserver

Parameters:

key - The key being appended to SSTable.

curPosition - The position of the key in the SSTable PRIMARY_INDEX file.

nextUnfilteredCluster

public void nextUnfilteredCluster(Unfiltered unfiltered)

Description copied from interface: SSTableFlushObserver

Called after the unfiltered cluster is written to the sstable. Will be preceded by a call to startPartition(DecoratedKey, long), and the cluster should be assumed to belong to that partition.

Specified by:

nextUnfilteredCluster in interface SSTableFlushObserver

Parameters:

unfiltered - The unfiltered cluster being added to SSTable.

complete

public void complete()

Description copied from interface: SSTableFlushObserver

Called when all data is written to the file and it's ready to be finished up.

Specified by:

complete in interface SSTableFlushObserver

getIndex

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Overrides:
