modernize-use-noexcept¶
This check replaces deprecated dynamic exception specifications with
the appropriate noexcept specification (introduced in C++11). By
default this check will replace throw()
with noexcept
,
and throw(<exception>[,...])
or throw(...)
with
noexcept(false)
.
Example¶
void foo() throw();
void bar() throw(int) {}
transforms to:
void foo() noexcept;
void bar() noexcept(false) {}
Options¶
-
ReplacementString
¶
Users can use
ReplacementString
to specify a macro to use instead ofnoexcept
. This is useful when maintaining source code that uses custom exception specification marking other thannoexcept
. Fix-it hints will only be generated for non-throwing specifications.
Example¶
void bar() throw(int);
void foo() throw();
transforms to:
void bar() throw(int); // No fix-it generated.
void foo() NOEXCEPT;
if the ReplacementString
option is set to NOEXCEPT.
-
UseNoexceptFalse
¶
Enabled by default, disabling will generate fix-it hints that remove
throwing dynamic exception specs, e.g., throw(<something>)
,
completely without providing a replacement text, except for
destructors and delete operators that are noexcept(true)
by
default.
Example¶
void foo() throw(int) {}
struct bar {
void foobar() throw(int);
void operator delete(void *ptr) throw(int);
void operator delete[](void *ptr) throw(int);
~bar() throw(int);
}
transforms to:
void foo() {}
struct bar {
void foobar();
void operator delete(void *ptr) noexcept(false);
void operator delete[](void *ptr) noexcept(false);
~bar() noexcept(false);
}
if the UseNoexceptFalse
option is set to false.
