Detailed Description

Maps object pointers to bit fields.

When scheduling maintenance for a range, the maintenance scheduler sometimes needs to schedule different maintenance tasks for different AccessGroups and CellStores within the range. This class was introduced to carry per-AccessGroup and per-CellStore maintenance task information from the scheduler to the Range. It's defined generically, but is used to map AccessGroup and CellStore pointers to corresponding bit fields describing what maintenance needs to be performed on them.

int Hypertable::MaintenanceFlag::Map::flags ( const void *  key )

inline

Returns bit field for a give pointer.

Parameters

key	Pointer for which to return bit field

Returns

Bit field correspoding to key
