Method Detail

main

public static void main(String[] args)
                 throws Exception

Instantiates and starts the Fractal application described by the given template name. Usage:

Launcher template [ itf ]

where template is the name of the template to be instantiated and started, and itf is the name of its Runnable interface.

This launcher initializes Fractal, constructs a composite parser component, uses it to parse the given template definition, instantiates the template component that just been parsed, starts the resulting component if it has a LifeCycleController interface, and starts a new thread to launch the application if the component provides a "run" interface of type Runnable.

Parameters:

args - the command line arguments.

Throws:

Exception - if a problem occurs.

getBootstrapParser

public static Parser getBootstrapParser()
                                 throws InstantiationException,
                                        NoSuchInterfaceException

Returns the bootstrap parser component. This component is created directly with the Fractal API (or even without it), since there is no pre existing parser component to create it from an XML template descriptor. Multiple calls to this method return the same component.

Returns:

the bootstrap parser component.

Throws:

InstantiationException - if the bootstrap parser cannot be created.

NoSuchInterfaceException - if the bootstrap type factory or generic factory interface cannot be found.
