Why you should care
Functions should not be defined with a variable number of arguments. Varargs methods are a convenient way to define methods that require a variable number of arguments, but they should not be overused. They can produce confusing results if used inappropriately.
How we detect
This Code Insight counts one occurrence each time the following pattern is detected in the source code:
void function ( String... strings )
{
// ...
}
