From 4ecbf7407c19b59fc136c334f9386c53db453930 Mon Sep 17 00:00:00 2001 From: zecke Date: Tue, 10 Dec 2002 17:01:18 +0000 Subject: get in sync with HEAD again -OPimBase was added to be used as a default struct inside OPimResolver and to work with DSOs -TodoListXML backend now uses mmap and madvise to load data -OContact added/changed rtti -OTodo added changed rtti OPimAccess* added stuff necessary for the Resolver and a 'state'/'hint' on how to load data OPimResolver which resolves uid + services to Records, rtti to QCOPChannels loads arbitary Service backends ( will work with DSOs soon ) -OPimMainWindow added some setDocument scripting possibility and internal marshalling and demarshalling of Records -OPimRecord added loadDataFromm and saveDataTo for marshalling purposes much more :) --- (limited to 'libopie2/opiepim/core') diff --git a/libopie2/opiepim/core/opimaccesstemplate.h b/libopie2/opiepim/core/opimaccesstemplate.h index 8cf81c8..259e2c1 100644 --- a/libopie2/opiepim/core/opimaccesstemplate.h +++ b/libopie2/opiepim/core/opimaccesstemplate.h @@ -22,20 +22,26 @@ template class OPimAccessTemplate : public OTemplateBase { public: + enum Access { + Random = 0, + SortedAccess + }; typedef ORecordList List; typedef OPimAccessBackend BackEnd; typedef OPimCache Cache; /** * c'tor BackEnd + * enum Access a small hint on how to handle the backend */ OPimAccessTemplate( BackEnd* end); + virtual ~OPimAccessTemplate(); /** * load from the backend */ - virtual bool load(); + bool load(); /** Reload database. * You should execute this function if the external database @@ -49,7 +55,7 @@ public: * Save is more a "commit".
