POTENTIAL_ROTTING_DOCUMENTATION /*! This static function returns the SoType object associated with name \a name. Type objects for builtin types can be retreived by name both with and without the "So" prefix. For dynamically loadable extension nodes, the name given to this function must match exactly. If no node type with the given name has been initialized, a dynamically loadable extension node with the given name is searched for. If one is found, it is loaded and initialized, and the SoType object for the newly initialized class type returned. If no module is found, or the initialization of the module fails, SoType::badType() is returned. Support for dynamically loadable extension nodes varies from platform to platform, and from compiler suite to compiler suite. So far code built with the following compilers are supported: GNU GCC v2-4, Microsoft Visual C++ v6, 2003, 2005 and 2008), SGI MIPSPro v7. Extensions built with compilers that are known to be binary compatible with the above compilers are also supported, such as e.g. the Intel x86 compiler compatible with MSVC++. To support dynamic loading for other compilers, we need to know how the compiler mangles the "static void classname::initClass(void)" symbol. If your compiler is not supported, tell us at \c [email protected] which it is and send us the output of a symbol-dump on the shared object. Typically you can do \code $ nm <Node>.so | grep initClass \endcode to find the relevant mangled symbol. */ SoType SoType::fromName(const SbName name) { static int enable_dynload = -1; if (enable_dynload == -1) { enable_dynload = TRUE; // the default setting const char * env = coin_getenv("COIN_NO_SOTYPE_DYNLOAD"); if (env && atoi(env) > 0) enable_dynload = FALSE; } assert((type_dict != NULL) && "SoType static class data not yet initialized"); // It should be possible to specify a type name with the "So" prefix // and get the correct type id, even though the types in some type // hierarchies are named internally without the prefix.
