Fallthrough in 'switch' statement
Reports 'fall-through' in a switch
statement.
Fall-through occurs when a series of executable statements after a case
label is not guaranteed to transfer control before the next case
label. For example, this can happen if the branch is missing a break
statement. In that case, control falls through to the statements after that switch
label, even though the switch
expression is not equal to the value of the fallen-through label. While occasionally intended, this construction is confusing and is often the result of a typo.
This inspection ignores any fall-through commented with a text matching the regex pattern (?i)falls?\s*thro?u
.
There is a fix that adds a break
to the branch that can fall through to the next branch.
Example:
After the quick-fix is applied:
