Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

An Uncommunicative Name is a name that doesn’t communicate its intent well enough.

Poor names make it hard for the reader to build a mental picture of what’s going on in the code. They can also be mis-interpreted; and they hurt the flow of reading, because the reader must slow down to interpret the names.

Currently UncommunicativeModuleName checks for

  • 1-character names

  • names ending with a number

See Uncommunicative-Module-Name for details.
