Overly long lambda expression

Reports lambda expressions whose number of statements exceeds the specified maximum.

Lambda expressions that are too long may be confusing, and it is often better to extract the statements into a separate method.

The following statements are not counted:

  • empty statements (semicolons)

  • block statements

  • for loop initialization statements, that is, int i = ... within a for(int i = ...;...) statement

  • for loop update statements, that is, i += 2 within a for(int i = ...;...; i += 2) statement

Use the Non-comment source statements limit field to specify the maximum allowed number of statements in a lambda expression.
