Package org.cumulus4j.store.query.method Description

Package providing handlers for various JDOQL/JPQL methods, utilising the index information and querying the backend datastore as necessary to access the DataEntry objects matching the particular method clause. Note that each method handler will typically evaluate a Boolean clause. This is simple for things like "Collection.isEmpty" which returns boolean, but for methods like String.substring() it has to be part of a comparison with some other String, and consequently caters for a most-used subset of the possible combinations.
