Qt Creator CDB Extensions
Qt Creator CDB extensions are loaded into CDB.exe (see cdbengine.cpp). They provide the following features:
- Notification about the state of the debugging session:- idle: (hooked with .idle_cmd) debuggee stopped
- accessible: Debuggee stopped, cdb.exe accepts commands
- inaccessible: Debuggee runs, no way to post commands
- session active/inactive: Lost debuggee, terminating.
 
- Hook up with output/event callbacks and produce formatted output
- Provide some extension commands that produce output in a standardized (GDBMI) format that ends up in handleExtensionMessage().
| Abstract base class for a node of SymbolGroup providing the child list interface | |
| The base class for a node of SymbolGroup with a flat list of children | |
| Debug filtering output visitor | |
| Debug output visitor | |
| Contains all parameters for GDBMI dumping of a symbol group in one class. The debugging engine passes maps of type names/inames to special integer values indicating hex/dec, etc | |
| GDBMI dump output visitor used to report locals values back to the debugging engine | |
| Creates a Symbol group representing the Locals view | |
| [fake] map node with a fake array index and key/value entries consisting of ReferenceSymbolGroupNode | |
| Qt information determined on demand | |
| Artificial node referencing another (real) SymbolGroupNode (added symbol or symbol from within an expanded linked list structure) | |
| Creates a symbol group storing a tree of expanded symbols rooted on a fake "locals" root element | |
| Represents a real node within a symbol group, identified by its index in IDebugSymbolGroup | |
| Visitor that iterates over the nodes and builds the full iname path ('local.foo.bar') that is required for GDBMI dumping | |
| Flyweight tied to a SymbolGroupNode providing a convenient operator[] (name, index) and value getters for notation of dumpers | |
| Passes all IDebug interfaces required for SymbolGroupValue | |
| Creates a watch symbol group |
