modernize-make-unique¶
This check finds the creation of std::unique_ptr
objects by explicitly
calling the constructor and a new
expression, and replaces it with a call
to std::make_unique
, introduced in C++14.
auto my_ptr = std::unique_ptr<MyPair>(new MyPair(1, 2));
// becomes
auto my_ptr = std::make_unique<MyPair>(1, 2);
This check also finds calls to std::unique_ptr::reset()
with a new
expression, and replaces it with a call to std::make_unique
.
my_ptr.reset(new MyPair(1, 2));
// becomes
my_ptr = std::make_unique<MyPair>(1, 2);
Options¶
- MakeSmartPtrFunction¶
A string specifying the name of make-unique-ptr function. Default is std::make_unique.
- MakeSmartPtrFunctionHeader¶
A string specifying the corresponding header of make-unique-ptr function. Default is <memory>.
- IncludeStyle¶
A string specifying which include-style is used, llvm or google. Default is llvm.
- IgnoreMacros¶
If set to true, the check will not give warnings inside macros. Default is true.
- IgnoreDefaultInitialization¶
If set to non-zero, the check does not suggest edits that will transform default initialization into value initialization, as this can cause performance regressions. Default is 1.
