PersistenceExtensions change to support date range query #418

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
1. Feature Description
Add method "getAllStatesBetweenTimes" to the class PersistenceExtensions to 
allow a date range query. Current methods only allow return of data FROM a time 
up to the current time.

2. Example Use Case
This enables a REST interface to be produced that supports historical queries 
and charting of data.

The implementation already implemented in the link below provides two methods - 
one using the default provider, and one using a named provider. This is 
consistent with other methods in this class.

As you have implemented the rest interface in a way that it directly accesses 
the persistence services, I think we won't need this feature anymore. Using it 
in rules might rather be a bit complex (and that's what the extensions are 
meant for).
