1.3 Module Interfaces
As a multi-chip standalone module, the physical interface to the JCM consists of a
keyboard, mouse, monitor, serial ports and network adapters.
The underlying logical interface to the module is the API, documented in the relevant
API Javadoc. The module provides the following four logical interfaces that have
been designed within the module where “
input” and “output” are indicated from
the perspective of the module:
• Control Input - the invocation of all methods, the function and API names
• Data Input - input arguments to all constructors and methods specifying input
parameters
• Data Output - modified input arguments, those passed by reference, and return
values for all constructors and methods modifying input arguments and returning
values
• Status Output - information returned by the methods and any exceptions thrown
by constructors and methods.
This is shown in the following diagram.
