Constructor Details

RangeMapping

public RangeMapping(ShardMapManager shardMapManager, RangeMappingCreationInfo creationInfo)

Constructs a range mapping given mapping creation arguments.

Parameters:

shardMapManager - Owning ShardMapManager.

creationInfo - Mapping creation information.

RangeMapping

public RangeMapping(ShardMapManager shardMapManager, ShardMap shardMap, StoreMapping mapping)
