The randomize.dat Initialization File
This file must be placed in the same directory as the user's proposal code files, and plays a role similar to the local models' .dat initialization files, though it has a much simpler structure. It also MUST be named randomize.dat, for this name is the only clue initpackage has to distinguish between creating a chain proposal or local models library.
All that needs to be entered into this file is a line of the form:
<class name> [<opt string arg1> <opt string arg2> ... <opt string argN>]for each proposal class that will go in the library. <class name> must be a case-sensitive match to the actual C++ class name, and is the only required entry on the line. The class should also be stored in code files <class name>.h and <class name>.cxx.
Any additional arguments on the line will be placed in a single C++ string (including any separating whitespace), and passed to the class constructor. This is to allow the option of setting initialization parameters at the class construction stage. Therefore if optional arguments are included, the class must have a constructor which takes a single string argument. Otherwise, the constructor should contain no arguments.
For example, a randomize.dat file declaring two classes might contain:
MyProposal1 MyProposal2 1.4773 on false
In the code files, the constructor declarations corresponding to this would then be:
MyProposal1.h
class MyProposal1 : public RandomizerBase
{
public:
// ...
MyProposal1();
// ...
};
MyProposal2.h
class MyProposal2 : public RandomizerBase
{
public:
// ...
MyProposal2(const string& initArgs);
// ...
};
