source: code/branches/consolecommands3/src/libraries/core/TclBind.h @ 7190

Last change on this file since 7190 was 7189, checked in by landauf, 14 years ago

changed passing of the returnvalue in the command execution pipeline:

  • Functor: operator() directly returns the returnvalue of the executed function (if any, otherwise a MultiType whose null() function evaluates to true). The returnvalue is no longer stored in the Functor.
  • Executor: The same behavior of operator() like in Functor. Additionally the parse() function returns the returnvalue of the executed function instead of a boolean status. The status can be retrieved by passing a pointer to a bool to the function.
  • CommandExecutor: execute() works like before (returns only a boolean status), but added a new function query() which returns the returnvalue of the executed command. The status of query() can be retrieved by optionally passing an pointer to a bool.
  • CommandEvaluation: same as for CommandExecutor: execute() like before, added query()
  • TclBind::eval() returns the returnvalue of the evaluated tcl command. The status can also be retrieved by passing a pointer to a bool.
  • The Shell prints the returnvalue (if available) of an executed command
  • added a constructor to MultiType to directly create it from an mbool. The mbool will be converted to a bool, so it loses it's internal state.
  • Property svn:eol-style set to native
