EPICS pvData C++
Overview
2010.08.10

Introduction

This project has the begining of the C++ implementation of pvData. The following is done:

introspection interfaces

The introspection interfaces for clients are described.

introspection implementation

The following have been implemented: Type, ScalarType, Field, Scalar

test

A test of Scalar.

As mentioned below there are problems with the current implementation.

Building

The project is structured as an epics base client application. Edit configure/RELEASE so that it references your EPICS base and then just type:

   make

At the top. Then execute the test in the bin directory.

pvDataApp has the following sub directories:

pv

pvData.h has the interface descriptions for client code.

factory

FieldCreateFactory.cpp has the current implementation

test

Has a test for the current implementation.

Questions about Classes

The pure virtual classes defined in pvData.h now work. But there are still some things that are not so nice. Amoung these are:

• In FieldCreateFactory.cpp look for "WHY DO I". It asks why the derived class must also define methods defined in the base class. If it does not then a compilation error occurs. WHY???
• The toString methods have an argument of "std::string &buf" instead of "std::string *". Does this seem correct?
• Can arguments and return descriptions be defined better?
• Is const present everywhere it should be? Remember that introspection classes are immutable.
• The code is NOT thread safe. When we decide for sure what thread/lock support to choose I will fix this.

HELP WILL BE GREATLY APPRECIATED. because I am still coming up to speed with c++

Garbage Collection

Not yet implemented. Lets get class structure correct first.
