Mikalai Parafeniuk commented on HAMA-524:
-
I thought that init method will be useful when user doesn't exactly knows
matrix size in creation time (for example, reading matrix from file). But you
are totally right, that it is easily to forget to call init method after
matrix creation. So I created new constructor in {{AbstractMatrixFormat}} and
{{AbstractVectorFormat}} classes. Constructor looks like this:
{code:java}
public AbstractMatrixFormat(int rows, int columns) {
this.rows = rows;
this.columns = columns;
init();
}
{code}
I think that RandomAccessSparse matrix format will be useful, so I added it.
Refactored code with new format can be found in my github repository. Thanks
for response, Thomas.

Re: Welcome Apurv Verma as new Apache Hama committer
Thank you all for your wishes. I look forward to this position of responsibility and I hope that I am able to match to the standards of the community . There are many things that I have to still learn though. About me: I am Apurv Verma and I am 21 years old. I live in Lucknow in India and I have a Bachelor's degree in Computer Science from Indian Institute of Technology, Ropar. I am interested in Java ,Distributed Systems and Data Structures. Some of the things that I want to learn in the near future are Machine Learning and Algorithm competitions. Apart from programming, I have a penchant for writing stories/poems, reading and travelling. I wish to travel the world and write at-least one good book in my lifetime ;) . I am also interested in spirituality and yoga. I would also like take this opportunity to thank some of the people who helped me in various ways, Thomas Jungblut, Edward Yoon, Suraj Menon and Praveen Sripati. Thank you all. BTW this Lucene tradition is really nice :) -- thanks and regards, Apurv Verma India (about.me/apurv.verma) On Wed, Jun 20, 2012 at 4:35 AM, Edward J.
