loadProperties

public static void loadProperties()

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

reInitialize

public static void reInitialize()

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 -

getMainPerspective

public KnowledgeFlowApp.MainKFPerspective getMainPerspective()

Gets the main knowledge flow perspective

Returns:

the main knowledge flow perspective

closeAllTabs

public void closeAllTabs()

clearLayout

public void clearLayout()

setModifiedStatus

public void setModifiedStatus(Object source,
                     boolean modified)

Tells us about the modified status of a particular object - typically a customizer that is editing a flow component. Allows us to set the modified flag for the current flow.

Specified by:

setModifiedStatus in interface BeanCustomizer.ModifyListener

Parameters:

source - the source object

modified - true if the source object has been modified

setPasteBuffer

public void setPasteBuffer(StringBuffer b)

Set the contents of the "paste" buffer and enable the paste from cliboard toolbar button

Parameters:

b - the buffer to use

getPasteBuffer

public StringBuffer getPasteBuffer()

Get the contents of the paste buffer

Returns:

the contents of the paste buffer

copyToBuffer

public StringBuffer copyToBuffer(Vector selectedBeans)
                          throws Exception

Utility routine that serializes the supplied Vector of BeanInstances to XML

Parameters:

selectedBeans - the vector of BeanInstances to serialize

Returns:

a StringBuffer containing the serialized vector

Throws:

Exception - if a problem occurs

propertyChange

public void propertyChange(PropertyChangeEvent e)

Accept property change events

Specified by:

propertyChange in interface PropertyChangeListener

Parameters:

e - a PropertyChangeEvent value

loadLayout

public void loadLayout(File oFile,
              boolean newTab)

Load a layout from a file. Supports loading binary and XML serialized flow files

Parameters:

oFile - the file to load from

newTab - true if the loaded layout should be displayed in a new tab

loadLayout

public void loadLayout(InputStream is,
              boolean newTab,
              String flowName)
                throws Exception

Load a flow file from an input stream. Only supports XML serialized flows.

Parameters:

is - the input stream to laod from

newTab - whether to open a new tab in the UI for the flow

flowName - the name of the flow

Throws:

Exception - if a problem occurs during de-serialization

loadLayout

public void loadLayout(Reader reader,
              boolean newTab,

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. The beans get added to the flow at position 0.

Parameters:

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

Throws:

Exception - if something goes wrong

getFlow

public Vector getFlow()
               throws Exception

Returns:

the current flow being edited

Throws:

Exception
