/**
 * Simple definition of a dynamic MBean, named "SimpleDynamic".
 *
 * The "SimpleDynamic" dynamic MBean shows how to expose for management
 * attributes and operations, at runtime,  by implementing the
 * "javax.management.DynamicMBean" interface.
 *
 * This MBean exposes for management two attributes and one operation:
 *      - the read/write "State" attribute,
 *      - the read only "NbChanges" attribute,

Git Workflow for Feature Branches

The following is an example workflow for developing on a temporary branch and merging back to the main branch squashing all commits into a single commit. This assumes you already have a branch named branch-xyz and have finished the work on that branch.

Step 1: Checkout the feature branch

git checkout branch-xyz

The following code is day-to-day operations when working with 3 forks: an open source project, a local fork of that project, and a company fork of that project. The power of Git is remote aliases that allow you to work with all 3 forks in parallel in the same code base and instantly compare, push, merge, etc.

Setup:

#> git clone [url of local fork: ie: username/project]
#> cd project
#> git remote add project [url of project: ie: project/project]
#> git remote add company [url of company fork: ie: company/project]
