DefaultStyledDocument.ElementBuffer JDK 1.6)

Hide/Show inherited methods

pack-private void advance (int n)

move the current offset forward by n.

pack-private void beginEdits (int offset, int length)

Initialize the buffer

pack-private boolean canJoin (Element e0, Element e1)

Can the two given elements be coelesced together into one element?

public void change (int offset, int length, DefaultDocumentEvent de)

Changes content.

protected void changeUpdate ()

Updates the element structure in response to a change in the document.

public Element clone (Element parent, Element clonee)

Creates a copy of this element, with a different parent.

pack-private Element cloneAsNecessary (Element parent, Element clonee, int rmOffs0, int rmOffs1)

Creates a copy of this element, with a different parent.

pack-private void create (int length, ElementSpec data, DefaultDocumentEvent de)

pack-private void endEdits (DefaultDocumentEvent de)

Creates the UndoableEdit record for the edits made in the buffer.

pack-private void fracture (int depth)

Determines if a fracture needs to be performed.

Determines if a fracture needs to be performed. A fracture can be thought of as moving the right part of a tree to a new location, where the right part is determined by what has been inserted. depth is used to indicate a JoinToFracture is needed to an element at a depth of depth. Where the root is 0, 1 is the children of the root...

This will invoke fractureFrom if it is determined a fracture needs to happen.

pack-private void fractureDeepestLeaf (ElementSpec specs)

Splits the bottommost leaf in path.

Splits the bottommost leaf in path.
This is called from insert when the first element is NOT content.

pack-private void fractureFrom (ElemChanges changed, int startIndex, int endFractureIndex)

Recreates the elements to the right of the insertion point.

Recreates the elements to the right of the insertion point.
This starts at startIndex in changed,
and calls duplicate to duplicate existing elements.
This will also duplicate the elements along the insertion
point, until a depth of endFractureIndex is
reached, at which point only the elements to the right of
the insertion point are duplicated.

public Element getRootElement ()

Gets the root element.

public void insert (int offset, int length, ElementSpec data, DefaultDocumentEvent de)

Inserts new content.

pack-private void insertElement (ElementSpec es)

pack-private void insertFirstContent (ElementSpec specs)

Inserts the first content.

protected void insertUpdate (ElementSpec data)

Inserts an update into the document.

pack-private Element join (Element p, Element left, Element right, int rmOffs0, int rmOffs1)

Joins the two elements carving out a hole for the given removed range.

pack-private void pop ()

pack-private void push (Element e, int index)

pack-private void push (Element e, int index, boolean isFracture)

Pushes a new element onto the stack that represents the current path.

pack-private Element recreateFracturedElement (Element parent, Element toDuplicate)

Recreates toDuplicate.

Recreates toDuplicate. This is called when an
element needs to be created as the result of an insertion. This
will recurse and create all the children. This is similiar to
clone, but deteremines the offsets differently.

public void remove (int offset, int length, DefaultDocumentEvent de)

Removes content.

pack-private boolean removeElements (Element elem, int rmOffs0, int rmOffs1)

Remove the elements from elem in range rmOffs0, rmOffs1.

Remove the elements from elem in range
rmOffs0, rmOffs1. This uses
canJoin and join to handle joining
the endpoints of the insertion.
Returns: true if elem will no longer have any elements.

protected void removeUpdate ()

Updates the element structure in response to a removal from the associated sequence in the document.

pack-private boolean split (int offs, int len)
