From 2ab51fbcdb1d26d635875174eb23f60d6f9dc6bb Mon Sep 17 00:00:00 2001 From: Andrew Schultz Date: Fri, 31 Oct 2003 17:32:04 -0500 Subject: Changed the naming of Serializeable derived objects. Serializeable no longer has objName as a member, instead it has the pure virtual function name(). SimObject now has a objName member, and all classes derived directly from Serializeable have to implement a name() function (which now makes them unique by pointer value) cpu/simple_cpu/simple_cpu.cc: Change initialization of Event to get rid of Serializeable naming dev/etherlink.cc: dev/etherlink.hh: Seralizeable derived naming changes sim/eventq.cc: Serializeable derived naming changes, also changed serialization process so it doesn't need to use nameChildren sim/eventq.hh: Serializeable derived naming changes, remove constructor for specifying event name sim/serialize.cc: Serializeable derived naming changes, remove setName function and the child naming pass for serialization sim/serialize.hh: Serializeable derived naming changes, removed nameChildren, setName sim/sim_object.cc: sim/sim_object.hh: Serializeable derived naming changes --HG-- extra : convert_revision : 67bcc275b6c210f7049f98a1ad0d22e8f5596a63 --- sim/eventq.cc | 54 ++++++++++++++++++++++++++---------------------------- sim/eventq.hh | 32 +++++++++++--------------------- sim/serialize.cc | 28 ++-------------------------- sim/serialize.hh | 12 +++--------- sim/sim_object.cc | 2 +- sim/sim_object.hh | 5 +++++ 6 files changed, 48 insertions(+), 85 deletions(-) (limited to 'sim') diff --git a/sim/eventq.cc b/sim/eventq.cc index ef813eb13..eab499bd9 100644 --- a/sim/eventq.cc +++ b/sim/eventq.cc @@ -150,55 +150,53 @@ Event::unserialize(Checkpoint *cp, const string §ion) } } - -void -EventQueue::nameChildren() -{ - int numEvents = 0;
