Redundant local variable

Reports an unnecessary local variable that does not make a function more comprehensible:

  • a local variable that is immediately returned

  • a local variable that is immediately assigned to another variable and is not used anymore

  • a local variable that always has the same value as another local variable or parameter.

Use the checkbox below to have this inspection ignore variables that are immediately returned or thrown. Some coding styles suggest using such variables for clarity and ease of debugging.
