Foil 40 Explicit Interfaces for
Mapping Dummy Arguments

From DoD HPF Training -- 4. HPF Data Mapping Facilities DoD Training and Others -- 1995-98. by Chuck Koelbel -- Rice University
1 An explicit interface is required if
  • Any dummy has a transcriptive mapping
    • Reason: The caller has to send a descriptor with the arrayıs mapping
  • Any dummy has the INHERIT attribute
    • Reason: The caller has to send a descriptor with the arrayıs mapping
  • For some argument, the actualıs mapping is not a specialization of the dummyıs
    • Translation: If the argument has to be remapped, you need an explicit interface
    • Reason: Somebody has to move the data around
