Overview

This is the Ruby representation of the IB Java EClient class. It adapts ruby invocations and arguments to invoke the corresponding Java API methods.

It is the object DRb clients get when connecting to the proxy service.

Mimicking how the Java API works, it collaborates with an IbWrapperAdapter that corresponds with an EWrapper in the Java world. It works by observing callbacks in this wrapper.

The usage of observers as a communication mechanism is because it is supported by DRb and, being DRb a standard implemented in JRuby, enables communicating Ruby and JRuby. If supporting other rubies was not required this level of indirection would be unnecessary.
