sg-cdb

Overview

sg-cdb is a pure Java version of D.J. Bernstein's constant database (cdb) package. Its API is the same as the one used in the original cdb library.

Files created with sg-cdb can be read with the cdb library and vice versa. My goal was to provide a seamless way of porting cdb code to a Java environment without the need for a JNI library.

More cdb information can be found at D.J. Bernstein's home page: http://cr.yp.to/cdb.html. Please do not send sg-cdb questions to Mr. Bernstein. He is not the maintainer of this implementation. A nice (with pictures) description of the format exists on UnixUser.org.

See the sg-cdb product page on the strangeGizmo.com site for more information on the basis of this fork.

This fork improves on the original by using Memory mapped NIO.

Continuous integration builds are performed by Travis-CI

Software metrics are tracked via SonarQube

Security vulnerabilities via Snyk

Released JAR files are available via

To add this to your build.gradle:

Add it in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
    }
}

Step 2. Add the dependency

dependencies {
        implementation 'com.github.duckAsteroid:sg-cdb:v1.0.6'
}
