change(int,int,AbstractDocument.DefaultDocumentEvent) .
|
Element | clone(Element parent, Element clonee) - Creates a copy of the element
clonee that has the parent
parent .
|
Element | getRootElement() - Returns the root element of this
ElementBuffer .
|

Element in the document at the specified
position.
|

ElementBuffer
public ElementBuffer(Element root)
Creates a new ElementBuffer
for the specified
root
element.
root
- the root element for this ElementBuffer
change
public void change(int offset,
int length,
AbstractDocument.DefaultDocumentEvent ev)
Modifies the element structure so that the specified interval starts
and ends at an element boundary. Content and paragraph elements
are split and created as necessary.
This also updates the
DefaultDocumentEvent
to reflect the
structural changes.
The bulk work is delegated to
changeUpdate()
.
offset
- the start index of the interval to be changedlength
- the length of the interval to be changedev
- the DefaultDocumentEvent
describing the change
clone
public Element clone(Element parent,
Element clonee)
Creates a copy of the element clonee
that has the parent
parent
.
parent
- the parent of the newly created Elementclonee
- the Element to clone
getRootElement
public Element getRootElement()
Returns the root element of this ElementBuffer
.
- the root element of this
ElementBuffer
insert
public void insert(int offset,
int length,
DefaultStyledDocument.ElementSpec[] data,
AbstractDocument.DefaultDocumentEvent ev)
offset
- the location in the document at which the content is
insertedlength
- the length of the inserted contentdata
- the element specifications for the content to be insertedev
- the document event that is updated to reflect the structural
changes
remove
public void remove(int offs,
int len,
AbstractDocument.DefaultDocumentEvent ev)
Updates the element structure of the document in response to removal of
content. It removes the affected
Element
s from the document
structure.
This method sets some internal parameters and delegates the work
to
removeUpdate()
.
offs
- the offset from which content is removelen
- the length of the removed contentev
- the document event that records the changes
removeUpdate
protected void removeUpdate()
Updates the element structure of the document in response to removal of
content. It removes the affected
Element
s from the document
structure.
