Dapper Dataflow Engine 0.92 (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:
On the fly generation and aliasing of dataflow graph edges are now possible. The API has been simplified, and redundant interfaces have been done away with; at the same time, dataflow graphs are now robust to tampering from malicious users. The concept of execution domain has been introduced to control what executes where. The manual is now substantially complete, and has been updated with a bevy of examples and diagrams. The SourceForge mailing lists dapper-user and dapper-announce have been created.Image

ost::BaseObject(3)					     Library Functions Manual						ost::BaseObject(3)

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.

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.
