I can do a simple test
What i do is extend DefaultStyledDocument so i can override the method
using reflection. Here is the code:
@Override
public void insert(int offset, ElementSpec[] data) throws
BadLocationException {
if (offset > getLength() || offset < 0) {
throw new BadLocationException("Invalid insert", offset);
}
if (data == null || data.length == 0) {
return;
}
writeLock();
try {
Content content = getContent();
//since instead of doing normal string insert we are going to
use the gapvector directly, we don't do this
//UndoableEdit cEdit = content.insertString(offset,
sb.toString());
int charArraysSize = 0;
int index = offset;
for (ElementSpec e : data) {
if (e.getLength() > 0) {
charArraysSize += e.getLength();
bulkArgs[0] = index;
bulkArgs[1] = e.getOffset();
bulkArgs[2] = e.getArray();
bulkArgs[3] = e.getLength();
index += e.getLength();
try {
replace.invoke(content, bulkArgs);
} catch (IllegalAccessException |
IllegalArgumentException | InvocationTargetException ex) {
throw new AssertionError(ex);
}
}
}
if (charArraysSize == 0) {
return;
}
//created the undoable edit corresponding to the whole inserted
string
//this can't be created because it is package protected in
gapvector
//UndoableEdit cEdit = new InsertUndo(offset, charArraysSize);
DefaultDocumentEvent evnt = new DefaultDocumentEvent(offset,
charArraysSize, DocumentEvent.EventType.INSERT);
//evnt.addEdit(cEdit);
buffer.insert(offset, charArraysSize, data, evnt);
// update bidi (possibly)
super.insertUpdate(evnt, null);
// notify the listeners
evnt.end();
fireInsertUpdate(evnt);
fireUndoableEditUpdate(new UndoableEditEvent(this, evnt));
} finally {
writeUnlock();
}
}
As you can see, i can't use undo-redo in this operation because the
undoable edit i need to create is package protected in GapContent - it's a
consequence of inlining the insertString function - but only for me, since
this change in DefaultStyledDocument would compile.
Obviously, the use of reflection would have to be replaced by a extension
method, and this method is mostly worthwhile if you have a buffered builder
that collects the ElementSpec's so as to insert them in bursts.
I have such a builder, and it would be nice to use them in the test to
simplify the building code. Can i use it?
