Constructor Detail

KnowledgeFlowApp

public KnowledgeFlowApp(boolean showFileMenu)

Creates a new KnowledgeFlowApp instance.

Method Detail

loadProperties

public static void loadProperties()

Loads KnowledgeFlow properties and any plugins (adds jars to the classpath)

setEnvironment

public void setEnvironment(Environment env)

Set the environment variables to use. NOTE: loading a new layout resets back to the default set of variables

Parameters:

env -

clearLayout

public void clearLayout()

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent e)

Accept property change events

Specified by:

propertyChange in interface java.beans.PropertyChangeListener

Parameters:

e - a PropertyChangeEvent value

setFlow

public void setFlow(java.util.Vector v)
             throws java.lang.Exception

Set the flow for the KnowledgeFlow to edit. Assumes that client has loaded a Vector of beans and a Vector of connections. the supplied beans and connections are deep-copied via serialization before being set in the layout.

Parameters:

v - a Vector containing a Vector of beans and a Vector of connections

Throws:

java.lang.Exception - if something goes wrong

getFlow

public java.util.Vector getFlow()
                         throws java.lang.Exception

Gets the current flow being edited. The flow is returned as a single Vector containing two other Vectors: the beans and the connections. These two vectors are deep-copied via serialization before being returned.

Returns:

the current flow being edited

Throws:

java.lang.Exception

saveLayout

public void saveLayout(java.io.OutputStream out)

Save the knowledge flow into the OutputStream passed at input. Only supports saving the layout data (no trained models) to XML.

Parameters:

out - the output stream to save the layout in

getGlobalInfo

public static java.lang.String getGlobalInfo(java.lang.Object tempBean)

Utility method for grabbing the global info help (if it exists) from an arbitrary object

Parameters:

tempBean - the object to grab global info from

Returns:

the global help info or null if global info does not exist

createSingleton

public static void createSingleton(java.lang.String[] args)

Create the singleton instance of the KnowledgeFlow

Parameters:

args - can contain a file argument for loading a flow layout (format: "file=[path to layout file]") Modified by Zerbetto: you can specify the path of a knowledge flow layout file at input

getSingleton

public static KnowledgeFlowApp getSingleton()

Return the singleton instance of the KnowledgeFlow

Returns:

the singleton instance

addStartupListener

public static void addStartupListener(StartUpListener s)

Add a listener to be notified when startup is complete

Parameters:

s - a listener to add

loadInitialLayout

public void loadInitialLayout(java.lang.String fileName)

Loads the specified file at input Added by Zerbetto

main

public static void main(java.lang.String[] args)

Main method.

Parameters:

args - a String[] value
