Class Method Details

.compile(module_name = nil, lib_name = nil, dir: Config::WorkDir) ⇒ Module

Compiles this class and makes a module including the compiled methods.

Parameters:

  • module_name (String) (defaults to: nil) —

    the name of the module where methods are attached. If it is not nil, a Ruby script is generated. When it is executed later, the methods are attached to the module with module_name. The name of the generated Ruby script is #{lib_name}.rb.

  • lib_name (String) (defaults to: nil) —

    the name of the generated library.

  • dir (String) (defaults to: Config::WorkDir) —

    the directory name where generated files are stored.

Returns:

  • (Module) —

    the module where methods are attached. Note that the name of this module is nil. It is not method_name.

end

.ocl_compile(module_name = nil, lib_name = nil, dir: Config::WorkDir, args: nil) ⇒ Module

Compiles this class and makes a module including the compiled OpenCL methods.

Parameters:

  • module_name (String) (defaults to: nil) —

    a module name.

  • lib_name (String) (defaults to: nil) —

    the name of the generated library.

  • dir (String) (defaults to: Config::WorkDir) —

    the directory name where generated files are stored. The default value is ..

  • args (Array<Object>) (defaults to: nil) —

    an array of the arguments to the initialize method. The default value is nil (no arguments).

Returns:

  • (Module) —

    the module where methods are attached.
