Detailed Description

the Measurements table

The Measurements table is a data structure for forwarding strategies to store per name prefix measurements. A strategy can access this table via Strategy::getMeasurements(), and then place any object that derive from StrategyInfo type onto Measurements entries.

find or insert an entry by name

An entry name can have at most getMaxDepth() components. If name exceeds this limit, it is truncated to the first getMaxDepth() components.
