The util package

We have these plugin interfaces and implementations in org.jtrix.project.beatrix.plugins.util:

AbstractPlugin

A simple plugin implementation which can be extended to make a useful plugin (Section ).

FileSystemLocator

Implementation of IFileSystemLocator (Section ).

IFileSystemLocator

Provides a tool for a manager to find a file system resource for a worker.

IInternalFacetCache

An internal facet is a facet provided by one Beatrix netlet to another within the same application. They aid inter-netlet/intra-application communication. This interface defines a tool to cache internal facets. See Section .

IRemoteServiceManager

An internal facet which one netlet can provide to another allowing the latter remote access to the former's service manager. See Section .

IServiceProvider

Provides services. Plugs into our ServiceManager implementation of IServiceManager. See Section .

ISimpleServiceProvider

Just like IServiceProvider, but is slightly less complex. See Section .

ISocketFactoryLocator

Defines a tool for a manager to find a socket factory resource for a worker. Once it has a socket factory a worker netlet can make its own network connections. See Section .

ITimer

Timer plugin similar to java.util.Timer, except that groups of tasks can be cancelled. See Section .

IWorkerPool

A worker pool is a collection point for plugins which support the deployment and running of workers of a specific type. It is added to a manager netlet. See Section .

IWorkerResourceRequester

Allows a plugin to specify resources required by workers. See Section .

InternalFacetCache

An implementation of IInternalFacetCache (Section ).

PluggablePluginManager

A plugin which is also a plugin manager. A lookup() method call gets passed to its own plugin manager if there's no match in itself.

RemoteServiceManager

An implementation of IRemoteServiceManager (Section ).

ServiceManager

An implementation of IServiceManager in the hooks package (Section ). Each IServiceProvider or ISimpleServiceProvider plugin added to to a ServiceManager provides a service to our application's consumers.

SocketFactoryLocator

An implementation of ISocketFactoryLocator (Section ).

TimerPlugin

An implementation of ITimer (Section ).

WorkerPool

An implementation of IWorkerPool. In this implementation workers from the same pool will always run on different nodes to aid redundancy. See Section .
