- """
- Class implementing the client side of the debugger.
-
- It provides access to the Python interpeter from a debugger running in
- another process whether or not the Qt event loop is running.
-
- The protocol between the debugger and the client assumes that there will be
- a single source of debugger commands and a single source of Python
- statements. Commands and statement are always exactly one line and may be
- interspersed.
-
- The protocol is as follows. First the client opens a connection to the
- debugger and then sends a series of one line commands. A command is either
- >Load<, >Step<, >StepInto<, ... or a Python statement.
- See DebugProtocol.py for a listing of valid protocol tokens.
-
- A Python statement consists of the statement to execute, followed (in a
- separate line) by >OK?<. If the statement was incomplete then the
- response is >Continue<. If there was an exception then the response
- is >Exception<. Otherwise the response is >OK<. The reason
- for the >OK?< part is to provide a sentinal (ie. the responding
- >OK<) after any possible output as a result of executing the command.
-
- The client may send any other lines at any other time which should be
- interpreted as program output.
-
- If the debugger closes the session there is no response from the client.
- The client may close the session at any time as a result of the script
- being debugged closing or crashing.
-
- <b>Note</b>: This class is meant to be subclassed by individual
- DebugClient classes. Do not instantiate it directly.
