[jira] [Updated] (GIRAPH-587) Refactor configuration options

["Nitay Joffe (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GIRAPH-587?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Nitay Joffe updated GIRAPH-587:
-------------------------------

    Description: 
Introduce smart helper clases to hold configuration options (IntConfOption, StrConfOption, ClassConfOption, etc).
This has many nice effects:
- Default value stored with the option key itself.
- Much simpler, less casting, clearer code. In other words, diff has more red than green :).
- Don't have to have two constants for every option (one for name, one for default value)
- Can do things with the options now that they're actual objects. For example with little code I added an AllOptions class that prints out all of the giraph options. See 

Some other things we could do:
- Add description into the object. Auto generate docs.
- Ensure that options begin with "giraph."

And so on.

Note there's no logic change here.



  was:I think with some clever use of Enums we can cleanup our configuration options a lot. Specifically I'm thinking we should add an enum for each type of option, for example StringConfOption. This enum would contain the key name, default value, and methods to get / set it when passed a Configuration. We can have a BooleanConfOption, IntConfOption, ClassConfOption, etc.
