Constructor Detail

CSLMImmutableSegment

protected CSLMImmutableSegment(Segment segment,
                               MemStoreSizing memstoreSizing)

------------------------------------------------------------------------ Copy C-tor to be used when new CSLMImmutableSegment is being built from a Mutable one. This C-tor should be used when active MutableSegment is pushed into the compaction pipeline and becomes an ImmutableSegment.
