The last planned day of the SteemJ Dev Diary was used to add the remaining 74 objects to the DatabaseApi.

SteemJ Dev Diary #7 (07.01.2018) - Finalize 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 #7

We made it - 7 days fully focused on SteemJ. Thanks to everyone who showed her/his interest and for your support in general. There is still a lot to do, but I guess this diary was really needed to get a good starting point for HF 0.20. related changes.

I also have to say that this series was quite exhausting, because 90% of the work had to follow three steps:

1. Check and analyze the Steem source code
2. Compare it against the current SteemJ implementation
3. Refactor, adjust and complement the existing code

To give you an idea about the work done in total:

• About ~100 files have been added
• 553 Files have been changed
• About 18.000 lines have been added
• And about 4.000 have been removed.

The work today was focused on the DatabaseApi again. As promised I've added all remaining objects and methods so that the 'DatabaseApi' is more or less ready to be tested and documented. The Screenshot below shows all methods that will be available.

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'

<dependency>
    <groupId>eu.bittrade.libs</groupId>
    <artifactId>steemj-core</artifactId>
    <version>0.4.3</version>
</dependency>

Start posting

SteemJConfig myConfig = SteemJConfig.getInstance();

myConfig.setDefaultAccount(new AccountName("YOUR-ACCOUNT"));

List<ImmutablePair<PrivateKeyType, String>> 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" });

Further information

The sample module of the SteemJ project provides showcases for the most common acitivies and operations users want to perform.

Beside that you can find a lot of snippets and examples in the different Wiki sections.

Contribute

The project became quite big and there is still a lot to do. If you want to support the project simply clone the git repository and submit a pull request. I would really appreciate it =).

git clone https://github.com/marvin-we/steem-java-api-wrapper.git

Get in touch!

Most of my projects are pretty time consuming and I always try to provide some useful stuff to the community. What keeps me going for that is your feedback and your support. For that reason I would love to get some Feedback from you <3. Just contact me here on Steemit or ping me on GitHub.
