Package com.hume.DMH Description

The DMH package implements client and server roles of the Hume Distributed Message Hub (DMH) inter-process communication message system. The DMH provides an easy-to-use way for multiple application processes to communicate in a distributed application. The DMH features message queueing which is a robust and high performance alternative to CORBA, SOAP, or similar RPC based systems.

The DMH package also provides classes to parse or construct text that is formatted as whitespace separated lists. Using String values to pass structured data bypasses the inflexibility and tedium of needing to use IDL or data structure definitions in many contexts of data sharing.
