MISRA C++:2008 Rule 15-5-2

Where a function's declaration includes an exception-specification, the function shall only be capable of throwing exceptions of the indicated type(s)

Description

Rule Definition

Where a function's declaration includes an exception-specification, the function shall only be capable of throwing exceptions of the indicated type(s).

Polyspace Implementation

The checker flags situations where the data type of the exception thrown does not match the exception type listed in the function specification.

For instance:

void goo ( ) throw ( Exception )
  { 
    throw 21; // Non-compliant - int is not listed
  }

The checker limits detection to throw statements that are in the body of the function. If the function calls another function, the checker does not detect if the called function throws an exception.

The checker does not detect throw statements inside catch blocks.

Troubleshooting

If you expect a rule violation but Polyspace® does not report it, see Diagnose Why Coding Standard Violations Do Not Appear as Expected.
