In my company we had to develop an api to monitor the execution of some
jobs (not quartz jobs but very simillar). I read in your project's
documentation that you don't provide any way of filtering the results of
the api. We had this issue before and solved it with the Guava Library.
Since your project is in Java it shouldn't be a problem use the Guava
Library. This library offers a lot of manipulations methods over
collections and filtering possibilities that simplifies the work a lot.
