static CommitLogArchiver	construct()
static CommitLogArchiver	disabled()
void	maybeArchive(CommitLogSegment segment)
void	maybeArchive(java.lang.String path, java.lang.String name) Differs from the above because it can be used on any file, rather than only managed commit log segments (and thus cannot call waitForFinalSync).
void	maybeRestoreArchive()
boolean	maybeWaitForArchiving(java.lang.String name)

maybeArchive

public void maybeArchive(CommitLogSegment segment)

maybeArchive

public void maybeArchive(java.lang.String path,
                         java.lang.String name)

Differs from the above because it can be used on any file, rather than only managed commit log segments (and thus cannot call waitForFinalSync). Used to archive files present in the commit log directory at startup (CASSANDRA-6904)

maybeWaitForArchiving

public boolean maybeWaitForArchiving(java.lang.String name)

maybeRestoreArchive
