LocalDate instances as consisting of three fields - year, month-of-year and day-of-month.īy contrast, users of this interface must think of dates as consisting of four fields -Įra, year-of-era, month-of-year and day-of-month. That decision ensures that developers can think of LocalDate shields users from the concept of eras, by ensuring that getYear() Maliciously written mutable implementation.ģ) Applications using this interface must consider the impact of eras. To accept a ChronoLocalDate could therefore be passed a poorly or There is nothing in the code or type system to enforce this. While the implementation notes indicate that all implementations must be immutable This should also be considered a extra cost in maintenance for the lifetime of the code.Ģ) This interface does not enforce immutability of implementations. The primary mechanism for reducing this increased risk of bugs is a strong code review process. The section below outlines how those assumptions can cause problems To code that is intended to deal with any arbitrary calendar system. A key cause of bugs is where the developerĪpplies assumptions from their day-to-day knowledge of the ISO calendar system These are some of the points that must be considered before using this interfaceġ) Applications using this interface, as opposed to using just LocalDate,įace a significantly higher probability of bugs. To use this interface as opposed to LocalDate. However, as explored below, abstracting the calendar system is usually the wrongĪpproach, resulting in logic errors and hard to find bugs.Īs such, it should be considered an application-wide architectural decision to choose This concept can seem surprising at first, as the natural way to globalize anĪpplication might initially appear to be to abstract the calendar system. Interface, even in the case where the application needs to deal with multiple The design of the API encourages the use of LocalDate rather than this The chronology defines how the calendar system operates and the meaning of Where most common implementations are defined in ChronoField. The date is defined in terms of fields expressed by TemporalField, Most applications should declare method signatures, fields and variablesĪ ChronoLocalDate is the abstract representation of a date where theĬhronology chronology, or calendar system, is pluggable. If you would include this feature i would personally petition for the developers saint hood! In general love the app and recommend it to people, but i will need further refinement before i start using it hard and heavy.A date without time-of-day or time-zone in an arbitrary chronology, intended If you could expand upon their functionality you would be a god among time keepers! Also, i desperately need to be able to record time on multiple tasks simultaneously, and currently you do not have this functionality. To the developer, check out the app Hours Keeper for invoicing functionality ideas. I need options and details when it comes to laying out my work for my customers at least. I hope they provide a more in-depth invoicing functionality. Invoicing was mentioned in previous reviews and I'm gonna jump on that band wagon. However, there are some subtleties that i do hope they fix soon. In general the app is fantastic and does exactly as advertised. Like other reviewers who have reviewed this app I too started with hours keeper and then migrated to this app for the multi-platform functionality. Well-designed, well thought out, nicely organized. With the ability to comment on each time section, i would easily give this 5 stars. Also, if I start and restart on a task, I want to be able to write what I got done the first time around vs the second time around. Or, I can leave a comment to mention/remind myself that the first 30 minutes were spent printing lecture slides, for instance, which while it is part of the homework assignment, its not actually time spent ON the assignment. For example, I spent a lot of time prepping for one homework assignment/whole class in general, which means some of the time seemingly spent on the homework assignment may have been better tracked in a different section. I wish there was a way to write notes/comment on each task however. I love how it tells the date and time when you started/stopped the task. It allows time tracking of multiple projects (or classes for instance) as well as how much time was spent for each "task" (or homework assignment). This app is well-thought out and the layout is perfect.
