BloombergLP::bslalg::ArrayPrimitives::defaultConstruct

Construct each of the elements of an array of the specified numElements of the parameterized TARGET_TYPE starting at the specified begin address by value‐initialization. If the (template parameter) ALLOCATOR type is derived from bslma::Allocator and TARGET_TYPE supports bslma allocators, then the specified allocator is passed to each TARGET_TYPE default constructor call. The behavior is undefined unless the output array contains at least numElements uninitialized elements after begin. If a TARGET_TYPE constructor throws an exception during this operation, then the destructor is called on any newly‐constructed elements, leaving the output array in an uninitialized state.
