Detailed Description

How ParameterSets are nested inside ParameterSets The main feature is that they're made persistent using a ParameterSetID, and only reconstituted as needed, when the value_ptr = 0;

This a basic exception type expected to be thrown by developer-written code. We recommend that you use it directly. It can also be used as a base class if needed.

Each Exception is identified by a category string. This category is a short word or phrase (no spaces) that described the problem that was encountered.

Information can be added to the Exception using the stream insertion operator (as one uses cout). We recommend using it in the following manner:

Example: if ((rc=func()) < 0) { throw cms::Exception("DataCorrupt") << "I died with rc = " << rc << std::endl; }

Derived types are expected to fix the category, either by 1) passing a string literal to the base class constructor, or 2) ensuring the developer gives a category name.

Example: class InfiniteLoop : public Exception { InfiniteLoop(const std::string& msg) : Exception("InfiniteLoop",msg) { } };

ExceptionCollector is a utility class that can be used to make sure that each function or functor in a sequence of calls is invoked even if a previous function throws. Each function/functor must take no arguments and return a void. std::bind can be used to convert a function taking arguments into a function taking no arguments. The exception strings are saved in a cms::Exception for optional rethrow.

Here is an example:

ExceptionCollector c("initialMessage");

c.call(std::bind(&MyClass::myFunction, myClassPtr)); c.call(std::bind(&MyClass::myOtherFunction, myClassPtr, myArgPtr)); c.call(std::bind(&myFreeFunction, myArgPtr)); if (c.hasThrown()) c.rethrow();

This insures that all three functions will be called before any exception is thrown.
