SteemJ Dev Diary #6 (06.01.2018) - Add new API methods to the DatabaseApi
Hello Steemians and welcome back to day #5 of the SteemJ HF 0.20 Dev Diary!
This series has been introduced to collect feedback from you and to motivate myself to finalize the next SteemJ version as soon as possible. If this is the first part of this series you read, you may want to checkout Day #1 which explains the motivation behind this diary in detail and also provides a first overview of the API changes that come with HF 0.20.
Changes during day #6
Todays focus was the 'DatabaseApi' which received the biggest update by the SteemDevs I would say. The future version of SteemJ will also support the great new API calls like 'list_vesting_delegations', 'list_escrows' or 'find_sbd_conversion_requests'. So far there was only one way of collecting those information: You had to index all blocks and search for those operations, so I really love to see those methods being implemented on Steem side.
As tomorrow is already the last, planned day of this diary series I will for sure try my best to finalize the 'DatabaseApi', so that I can hopefully share a Screenshot of all available methods with you tomorrow.
Beside this change I was able to close some smaller issues by removing deprecated fields, adding a License Header to all files and by adding the Issue section to all poms.
List of fixed issues: * IS #197 * IS #165 * IS #161
Full list of commits: * ce7a7b * ada03f * 88fd3b * f2d88c * cb4ecd * 180fe6 * f56d93 * c19f2e

General information
What is SteemJ?
SteemJ is a project that allows you to communicate with a Steem node using Java. So far, the project supports most of the API calls and is also able to broadcast most of the common operation types. Further information can be found on GitHub.

Quick Start Guide
Add SteemJ to your project
SteemJ binaries are pushed into the maven central repository and can be integrated with a bunch of build management tools like Maven. The Wiki provides a lot of examples for the most common build tools. If you do not use a build management tool you can download the binaries as described here.
To add this release to your project paste the following snippet into your 'pom.xml'
eu.bittrade.libs

Start posting
SteemJConfig myConfig = SteemJConfig.getInstance();
myConfig.setDefaultAccount(new AccountName("YOUR-ACCOUNT"));
List> privateKeys = new ArrayList<>();
privateKeys.add(new ImmutablePair<>(PrivateKeyType.POSTING, "YOUR-PRIVATE-POSTING-KEY"));
myConfig.getPrivateKeyStorage().addAccount(myConfig.getDefaultAccount(), privateKeys);
steemJ.createComment(new AccountName("steemj"), new Permlink("testofsteemj040"), "Example comment without no link but with a @user .", new String[] { "test" });
