Constructor Details

DefaultVersionedPartitions

public DefaultVersionedPartitions()

Default no-arg constructor.

DefaultVersionedPartitions

public DefaultVersionedPartitions(VersionedPartitions versions)

Copy-like constructor based on the provided VersionedPartitions.

Parameters:

versions - the VersionedPartitions to copy / clone from

DefaultVersionedPartitions
