The GetOrCreateCompiler method in the CompileGroup class is responsible for retrieving an existing compiler by its name or creating a new one if it does not exist. This method ensures that a compiler with the specified name is available for use, either by returning an existing instance or by creating a new one.

To use the GetOrCreateCompiler method, you need to have an instance of the CompileGroup class. Call the method with the desired compiler name as a string parameter. The method will return a Compiler object.

Example usage:

CompileGroup compileGroup = new CompileGroup();
Compiler compiler = compileGroup.GetOrCreateCompiler("MyCompiler");

In this example, "MyCompiler" is the name of the compiler you want to retrieve or create. The method will return the corresponding Compiler object.
