newLog- the Logger that will now get info messages
-
requiresLog
public boolean requiresLog()Description copied from class:AbstractPerspectiveWhether this perspective requires a graphical log to write to- Specified by:
requiresLogin interfacePerspective- Overrides:
requiresLogin classAbstractPerspective- Returns:
- true if a log is needed by this perspective
-
setInstances
Tells the panel to use a new base set of instances.- Specified by:
setInstancesin interfaceExplorer.ExplorerPanel- Specified by:
setInstancesin interfacePerspective- Overrides:
setInstancesin classAbstractPerspective- Parameters:
inst- a set of Instances
-
getInstances
Gets the working set of instances.- Returns:

Adds a PropertyChangeListener who will be notified of value changes.- Overrides:
addPropertyChangeListenerin classContainer- Parameters:
l- a value of type 'PropertyChangeListener'
-
removePropertyChangeListener
Removes a PropertyChangeListener.- Overrides:
removePropertyChangeListenerin classComponent- Parameters:
l- a value of type 'PropertyChangeListener'
-
saveWorkingInstancesToFileQ
public void saveWorkingInstancesToFileQ()Queries the user for a file to save instances as, then saves the instances in a background process. This is done in the IO thread, and an error message is popped up if the IO thread is busy. -
saveInstancesToFile
saves the data with the specified saver- Parameters:
saver- the saver to use for storing the datainst- the data to save
-
setInstancesFromFileQ
public void setInstancesFromFileQ()Queries the user for a file to load instances from, then loads the instances in a background process. This is done in the IO thread, and an error message is popped up if the IO thread is busy. -
setInstancesFromDBQ
Loads (non-sparse) instances from an SQL query the user provided with the SqlViewerDialog, then loads the instances in a background process. This is done in the IO thread, and an error message is popped up if the IO thread is busy.- Parameters:
url- the database URLuser- the user to connect aspw- the password of the userquery- the query for retrieving instances from
-
setInstancesFromDBQ
Loads instances from an SQL query the user provided with the SqlViewerDialog, then loads the instances in a background process. This is done in the IO thread, and an error message is popped up if the IO thread is busy.- Parameters:
url- the database URLuser- the user to connect aspw- the password of the userquery- the query for retrieving instances fromsparse- whether to create sparse or non-sparse instances
-
setInstancesFromURLQ
public void setInstancesFromURLQ()Queries the user for a URL to load instances from, then loads the instances in a background process. This is done in the IO thread, and an error message is popped up if the IO thread is busy. -
generateInstances
public void generateInstances()sets Instances generated via DataGenerators (pops up a Dialog) -
setInstancesFromFile
Loads results from a set of instances retrieved with the supplied loader. This is started in the IO thread, and a dialog is popped up if there's a problem.- Parameters:
loader- the loader to use
-
setInstancesFromDB
Loads instances from a database- Parameters:
iq- the InstanceQuery object to load from (this is assumed to have been already connected to a valid database).
-
setInstancesFromURL
Loads instances from a URL.- Parameters:
u- the URL to load from.
-
addUndoPoint
Backs up the current state of the dataset, so the changes can be undone.- Throws:
Exception- if an error occurs
-
undo

-
setActive
public void setActive(boolean active) Description copied from class:AbstractPerspectiveSet active status of this perspective. True indicates that this perspective is the visible active perspective in the application- Specified by:
