Overview

See Hoodoo::Communicators::Pool for details.

A “fast communicator”. Subclass this to create a class where instances are invoked via Hoodoo::Communicators::Fast#communicate with some parameter and, in response, they talk to some other piece of software to communicate information related to that parameter. The communication is expected to be fast and will be called from Ruby’s main execution thread.

If the communicator takes a long time to complete its operation, other processing will be delayed. If you expect this to happen, subclass Hoodoo::Communicators::Slow instead.

Example: A communicator might be part of a logging scheme which writes to STDOUT. The parameter it expects would be a log message string.
