load
public void load(Properties props, String prefix, boolean treatAsCurrent) throws IllegalArgumentException Load this rate stat from the properties, populating all of the rates contained underneath it. The comes from the given prefix (e.g. if we are given the prefix "profile.dbIntroduction", a series of rates may be found underneath "profile.dbIntroduction.60s", "profile.dbIntroduction.60m", and "profile.dbIntroduction.24h"). This RateStat must already be created, with the specified rate entries constructued - this merely loads them with data.- Parameters:
prefix
- prefix to the property entries (should NOT end with a period)treatAsCurrent
- if true, we'll treat the loaded data as if no time has elapsed since it was written out, but if it is false, we'll treat the data with as much freshness (or staleness) as appropriate.- Throws:
IllegalArgumentException
- if the data was formatted incorrectly
