code::LBInterface Class Reference

List of all members.

Detailed Description

Private Implementation class of LinearBuffer.

Every LinearBuffer holds a pointer to a LBInterface which it obtains from the list of all LBs maintained in LBInterfaceList. The LBInterface will open a LB not yet opened and add it to that list if necessary.

The LBInterface holds a pointer to a LBInterfaceInfo which is resolved to determine whether LB calls should be made locally or remotely.
