class LoadFileCommand
extends Command

This class is a type of Command that represents a request to use Jython to run a file containing Jython statements. This is conceptually a bit similar to importing a module, but the loading is done behind the scenes and you may specify whatever namespace you like (be careful!).

Constructor Details

LoadFileCommand

public LoadFileCommand(Console console,
 String name,
 String path)

Creates a command that will attempt to execute a Jython file in the namespace given by name.

Parameters:

console - Originating console.

name - Namespace to use when executing path.

path - Path to a Jython file.

Method Details

execute

public void execute(Interpreter interpreter)
             throws Exception

Tries to load the file specified by path using moduleName for the __name__ attribute. Note that this command does not currently display any results in the originating Console.

If moduleName is not __main__, this command is basically the same thing as doing from moduleName import *.

If moduleName is __main__, then this command will work for if __name__ == '__main__' and will run main functions as expected.

Specified by:

execute in class Command

Parameters:

interpreter - Interpreter to use to load the specified file.

Throws:

Exception - if Jython has a problem with running path.

toString

public String toString()

Overrides:

toString in class Object
