Detailed Description

A NullLogEntryWriter can be used completely disable all logging programmatically as long as it exists.

In this way it is similar to a LogChecker, but does not actually send log messages anywhere. Note that this does NOT prevent FATAL, DFATAL, or DCHECKs from calling the currently installed break handler.

You can disable logging for a scope like this: { NullLogEntryWriter null_logger; ... ///< Very verbose code. } // Old writer is restored when the null logger passes out of scope.

Alternatively, managing the life of the instance can disable logging for longer periods, for example: #if ION_PRODUCTION std::unique_ptr<NullLogEntryWriter> null_logger(new NullLogEntryWriter); #endif could be used to completely disable logging in an application when building for production mode.
