Can use custom logger with default

[kaero]

Why you needs in so complex solution? Default logger is not something special. Keep original logger, if you want to use built-in logger and your own logging solution:

var CustomError = Terror.create('CustomError'),

CustomError.setLogger(function(message, level) {
    // your own stuff
    log.push([message, level]);

    // call built-in logger
    Terror.prototype.logger.call(this, message, level);
});

If you want to use multiple loggers, you can implement desired API in application common error class:

var ApplicationError = Terror.create('ApplicationError');

ApplicationError.addLogger = ...
ApplicationError.removeLogger = ...
ApplicationError.removeDefaultLogger = ...

var ConnectionError = ApplicationError.create('ConnectionError')
    .addLogger(fucntion(...) { ... });

or you can use solutions like winston for multitarget logging.

In any case, support for multiple loggers doesn't looks to be core terror functionality.
