Etymology

Null as in "empty" or "/dev/null".

Synopsis

NullLogSink is a trivial LogSinkInterface which merely throws away all its messages. It is not intended to be used directly, rather it should be used through LogSink.

Example

See (see (file="Logging.h"))Logging.h.

Motivation

For testing, or to prevent multiply logging (local and global) to cerr (say).

To Do

Definition at line 74 of file NullLogSink.h.
