|
|
\brief The PointerDeclarationFormatter class rewrites pointer or reference
|
|
declarations to an Overview.
|
|
|
|
The following constructs are supported:
|
|
\list
|
|
\li Simple declarations
|
|
\li Parameters and return types of function declarations and definitions
|
|
\li Control flow statements like if, while, for, foreach
|
|
\endlist

This enum type simplifies the QuickFix implementation.
|
|
|

\value RespectCursor
|
|
Consider the cursor position or selection of the CppRefactoringFile
|
|
for rejecting edit operation candidates for the resulting ChangeSet.
|
|
If there is a selection, the range of the edit operation candidate
|
|
should be inside the selection. If there is no selection, the cursor
|
|
position should be within the range of the edit operation candidate.
|
|
\value IgnoreCursor
|
|
Cursor position or selection of the CppRefactoringFile will
|
|
_not_ be considered for aborting.
