Unnecessary local variable
Reports local variables that are used only in the very next return
statement or are exact copies of other variables.
Such variables can be safely inlined to make the code more clear.
Example:
fun sum(a: Int, b: Int): Int {
val c = a + b
return c
}
After the quick-fix is applied:
fun sum(a: Int, b: Int): Int {
return a + b
}
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
UnnecessaryVariable
Configure the inspection:
Use the Report immediately returned variables option to report immediately returned variables. When given descriptive names, such variables may improve the code readability in some cases, that's why this option is disabled by default.
Here you can find the description of settings available for the Unnecessary local variable inspection, and the reference of their default values.
