Dapper Dataflow Engine 0.95 (Default branch)

Image Dapper, or "Distributed and Parallel Program Execution Runtime", is a tool for taming the complexities of developing for large-scale cloud and grid computing, enabling the user to create distributed computations from the essentials: the code that will execute, along with a dataflow graph description. It supports rich execution semantics, carefree deployment, a robust control protocol, modification of the dataflow graph at runtime, and an intuitive user interface. License: GNU Lesser General Public License (LGPL) Changes:
A new, flexible logging infrastructure has been added. Initializers for logging structures have been moved out of the Server and Client classes and into drivers. Finite state machines have been updated to the new annotation-driven API. The source code has been normalized to have 8 spaces instead of tabs. Image

NAME
ost::BaseObject - BaseObject. SYNOPSIS
#include <persist.h> Public Member Functions BaseObject () This constructor is used in serialisation processes. virtual ~BaseObject () Default destructor. virtual const char * getPersistenceID () const This returns the ID of the persistent object (Its type) virtual bool write (Engine &archive) const This method is used to write to the Persistence::Engine It is not equivalent to the << operator as it writes only the data and not the object type etc. virtual bool read (Engine &archive) This method is used to read from a Persistence::Engine It is not equivalent to the >> operator as it does no typesafety or anything. Detailed Description BaseObject. This object is the base for all Persistent data which is not natively serialised by the Persistence::Engine It registers itself with the Persistence::TypeManager using a global constructor function. A matching deregister call is made in a global destructor, to allow DLL's to use the Persistence::Engine in a main executable. Persistable objects must never maintain bad pointers. If a pointer doesn't point to something valid, it must be NULL. This is so the persistence engine knows whether to allocate memory for an object or whether the memory has been pre-allocated. Author: Daniel Silverstone Base class for classes that will be persistent. Constructor &; Destructor Documentation ost::BaseObject::BaseObject () This constructor is used in serialisation processes. It is called in CreateNewInstance in order to create an instance of the class to have Read() called on it. virtual ost::BaseObject::~BaseObject () [virtual] Default destructor. Member Function Documentation virtual const char* ost::BaseObject::getPersistenceID () const [virtual] This returns the ID of the persistent object (Its type) virtual bool ost::BaseObject::read (Engine &archive) [virtual] This method is used to read from a Persistence::Engine It is not equivalent to the >> operator as it does no typesafety or anything. virtual bool ost::BaseObject::write (Engine &archive) const [virtual] This method is used to write to the Persistence::Engine It is not equivalent to the << operator as it writes only the data and not the object type etc. Author Generated automatically by Doxygen for GNU CommonC++ from the source code.
