Besides OSGi services, the E4AP also exposes other services that can be consumed by clients.
Logging
The org.eclipse.e4.core.services.log.Logger class provides clients with a number of convenience methods for logging information. Some of its methods takes Object[] arrays and will perform binding internally to format the message appropriately.
void debug(String message); void info(Throwable t); void trace(String message, Object[] args)
Adapter Pattern
The org.eclipse.e4.core.services.adapter.Adapter interface provides a way for clients to adapt an object to another type. This is akin to the org.eclipse.core.runtime.IAdapterFactory and org.eclipse.core.runtime.IAdaptable interfaces from Eclipse 3.x.
