What is Generic Connection Framework?

February 16th, 2008 by uCertify Leave a reply »

The Generic Connection Framework (GCF) is a J2ME API defined to support wireless networking. It has the following interfaces:

  • Connection
  • StreamConnectionNotifier
  • InputConnection
  • OutputConnection
  • DatagramConnection
  • StreamConnection
  • ContentConnection

The Connection interface is at the top of the interface hierarchy.

Initially GCF was defined to provide wireless support to CLDC 1.0 because java.net and java.io APIs are too large for resource-constrained devices. But now it provides support to CLDC 1.1 and CDC as well.
