Plug-in entry points

Every plug-in must implement both initializePlugin() and uninitializePlugin() functions as entry points into the plug-in. These functions register and deregister the additions to Maya defined in the plug-in.

initializePlugin() is called when Maya loads the plug-in. It contains code to register the commands, nodes, tools, and other additions to Maya defined by the plug-in.

uninitializePlugin() is called when the plug-in is unloaded. It deregisters anything that was registered when the plug-in was loaded.

For a command plug-in, initializePlugin() must call registerCommand() to register the command. Similarly, uninitializePlugin() calls deregisterCommand().

For a dependency node plug-in, initializePlugin() must call registerNode() to register the command. Similarly, uninitializePlugin() calls deregisterNode().

The plug-in will fail to load if either initializePlugin() or uninitializePlugin() is missing.

Examples of how to implement these functions can be found in any of the devkit plug-in examples.
