Field Detail

_hasPrompt

private volatile boolean _hasPrompt

Whether the document currently has a prompt and is ready to accept input.

_toClear

private volatile boolean _toClear

A flag indicating that the interpreter was recently reset, and to reset the styles list the next time a style is added. Cannot reset immediately because then the styles would be lost while the interactions pane is resetting.

UNDO_LIMIT

private static final int UNDO_LIMIT

See Also:

Constant Field Values

_undoManager

private volatile CompoundUndoManager _undoManager

_isModifiedSinceSave

private volatile boolean _isModifiedSinceSave

_notifier

private volatile GlobalEventNotifier _notifier

_stylesList

private List<Pair<Pair<Integer,Integer>,String>> _stylesList

A list of styles and their locations augmenting this document. This augmentation is NOT part of the reduced model; it a separate extension that uses itself as a mutual exclusion lock. This list holds pairs of location intervals and strings (identifying styles). In essence it maps regions to colors (??). in the document and styles, which is basically a map of regions where the coloring view that is now attached to the Interactions Pane. It is not allowed to use the reduced model to determine the color settings when rendering text. (Why not? -- Corky) We keep a list of all places where styles not considered by the reduced are being used, such as System.out, System.err, and the various return styles for Strings and other Objects. Since the LinkedList class is not thread safe, we have to synchronized all methods that access pointers in _stylesList and the associated boolean _toClear.

Constructor Detail

InteractionsDJDocument

public InteractionsDJDocument()

Standard constructor.

InteractionsDJDocument

public InteractionsDJDocument(GlobalEventNotifier notifier)

Method Detail

hasPrompt

public boolean hasPrompt()

Specified by:

hasPrompt in interface ConsoleDocumentInterface

Returns:

true iff this document has a prompt and is ready to accept input.

setHasPrompt

public void setHasPrompt(boolean val)

Sets the _hasPrompt property.

Specified by:

setHasPrompt in interface ConsoleDocumentInterface

Parameters:

val - new boolean value for _hasPrompt.

_styleChanged

protected void _styleChanged()

Description copied from class: AbstractDJDocument

Fire event that styles changed from current location to the end. Right now we do this every time there is an insertion or removal. Two possible future optimizations:

1. Only fire changed event if text other than that which was inserted or removed *actually* changed status. If we didn't changed the status of other text (by inserting or deleting unmatched pair of quote or comment chars), no change need be fired.
2. If a change must be fired, we could figure out the exact end of what has been changed. Right now we fire the event saying that everything changed to the end of the document.

I don't think we'll need to do either one since it's still fast now. I think this is because the UI only actually paints the things on the screen anyway.

Specified by:

_styleChanged in class AbstractDJDocument

getUndoManager

public CompoundUndoManager getUndoManager()

Getter method for CompoundUndoManager

Returns:

_undoManager

resetUndoManager
