In the SourceViewerConfiguration class, There is 2 method,
getDefaultPrefix and getIndentPrefixes. The questions are:
1. about the getDefaultPrefix. The document says that "Returns the
default prefixes to be used by the line-prefix operation", so, what is
the line-prefix operation?
2. about the getIndentPrefixes. The document says that "Returns the
prefixes to be used by the line-shift operation", and what is the
line-shift operation.(Is it the auto indent??).
Any example is welecome.
Thanks.

Hi,
Line prefix operation == Comment line (prefix the line with //)
Line shift operation == Tab / Shift+Tab
Take a look at the TextViewer.doOperation(int op) .
>>
case SHIFT_RIGHT:
shift(false, true, false);
break;
case SHIFT_LEFT:
shift(false, false, false);
break;
case PREFIX:
shift(true, true, true);
break;
The shift() method can be configured to use a specific defaultPrefix (//
or # ...) and indentPrefix (\t or space ...).
The SourceViewerConfiguration is used to configure the source viewer
(ISourceViewer#configure(SourceViewerConfiguration)).

Hi,
First, thanks for your help.
And there is another problem:
In my own text editor, I want the comment and uncomment (just like in
the java editor, you press the Ctrl + /, the rows selected are commented
or uncommented). So I followed what the jdt does: a command and a
binding, but what my editor does is different, it always comment the
selected rows even if they are commentd already. And in the jdt, I find
a command "uncomment", but no binding to this command.
and what should i do to make my editor works just like the java editor?
Hope that you can understand me.

There is only one action, the 'ToggleComment' action.
>>
if (isSelectionCommented(selection))
operationCode= ITextOperationTarget.STRIP_PREFIX; //uncomment
else
operationCode= ITextOperationTarget.PREFIX; //comment
Take a look at this class
org.eclipse.jdt.internal.ui.javaeditor.ToggleCommentAction
