For GEODE-3813 <https://issues.apache.org/jira/browse/GEODE-3813>: Region registerInterest API usage of type parameters is broken <https://issues.apache.org/jira/browse/GEODE-3813>
The current API to registerInterest allows a special string token “ALL_KEYS” to be passed in as the parameter to registerInterest(T key). This special token causes the registerInterest to behave similar to registerInterestRegex(“.*”). As the ticket states, if the region has been typed to anything other than Object or String, the usage of “ALL_KEYS” as a parameter results in a compilation error. Proposals: I would like to deprecate the special string “ALL_KEYS” and document a workaround of using registerInterestRegex(“.*”) or we can add a new API called registerInterestAllKeys() I think we should also deprecate passing a List Object of keys into registerInterest. It has the same compilation restrictions as “ALL_KEYS” when the region is key constrained/typed. The reason why List would be used is to allow registering multiple keys at once. Instead, we can add a new var arg API like registerInterest(T… keys). This problem and solution was also documented in the ticket by the ticket creator (Kirk Lund) Thanks, -Jason
