説明

Describe the bug

Given the following code:

val range: ClosedRange<Int> = 0..1
check(!range.isEmpty())

Diktat suggests replacing this with the nonexistent ClosedRange.isNotEmpty() function:

[INVERSE_FUNCTION_PREFERRED] it is better to use inverse function: isNotEmpty() instead of !isEmpty() (diktat-ruleset:inverse-method)

Expected behavior

Rule should not be triggered when the isNotEmpty function does not exist.

Environment information

  • diktat version: 1.2.5
  • how is diktat run (CLI, plugin, etc.): CLI
