a designers dilemma

i have a thought in mind. I took a notebook and thought through it through a pencil. I think it will work. It is all in my mind. laid out in a map. I just have to implement it.

how can i pass it on to someone that can implement it without loosing the fidelity of my thought! what tools do I have?

what if I do this

I create the java classes. roughly. create the methods. describe what should happen in each method.

then, Can someone else fill in the blanks. compile the code, test the code?

Perhaps a white paper instead

what instead, if I just take into account all the possible options of the design and their alternatives and lay out a white paper with possible solutions. This should let someone help to implement it!!

Here is an example, perhaps


/*
    * Take the input post
    * the keys are user defined fields
    * the keys should be mapped to their storage keys
    * use InsertStatement as a conduit to get this done
    */
   public List<InsertStatement>
   getInsertStatements(Map<String,String> submittedListRow)
   {
      return null;
   }

what about pure interfaces? will they help?

satya - Sat Apr 07 2012 10:29:35 GMT-0400 (Eastern Daylight Time)

I wonder if a 'crowd' can implement a class simultaneously!

'Crystalization' is an important practice in 'work' and as well in 'programming'

ask me if you are curious!!

yes I have a twitter account

eclipse is just an incredible tool!!!

wonder if there is a better way to put meaning into a map


//Map<StorageColumnName, StorageColumnValue>
private Map<String,String> attributeValues
   = new HashMap<String,String>();

Here are some notes on eclipse as you program in Java

satya - Mon Apr 09 2012 15:02:42 GMT-0400 (Eastern Daylight Time)

Use asserts for key validations on the state of a class

satya - Mon Apr 09 2012 15:07:06 GMT-0400 (Eastern Daylight Time)

You can do this with eclipse...

In a java function you can start typing

SQL

and then press ctrl-space. eclipse may prompt you that with

SQLQuote

and complete the possible class name for it. that's nice!!!

State first Code next principle

write down your function names in your skeleton class. Document in English what each function is supposed to do. Then code it.

even when coding vocalize what you are doing in comments. then code it.

The idea of classes help 'Work-Crystalization' idea

satya - Tue Apr 10 2012 11:03:38 GMT-0400 (Eastern Daylight Time)

It will be nice to design classes such a way that MOST are testable through unit test cases

satya - Tue Apr 10 2012 11:49:15 GMT-0400 (Eastern Daylight Time)

May be not! look for key boundaries.

Provide test cases at those boundaries and that test should trickle down the lower classes and save you some time.
