| -// AlignedMemory is a POD type that gives you a portable way to specify static
|
| -// or local stack data of a given alignment and size. For example, if you need
|
| -// static storage for a class, but you want manual control over when the object
|
| -// is constructed and destructed (you don't want static initialization and
|
| -// destruction), use AlignedMemory:
|
| -//
|
| -// static AlignedMemory<sizeof(MyClass), ALIGNOF(MyClass)> my_class;
|
| -//
|
| -// // ... at runtime:
|
| -// new(my_class.void_data()) MyClass();
|
| -//
|
| -// // ... use it:
|
| -// MyClass* mc = my_class.data_as<MyClass>();
|
| -//
|
| -// // ... later, to destruct my_class:
|
| -// my_class.data_as<MyClass>()->MyClass::~MyClass();
|
| -//
|
| -// Alternatively, a runtime sized aligned allocation can be created:
|
| -//
|
| -// float* my_array = static_cast<float*>(AlignedAlloc(size, alignment));
|
| -//
|
| -// // ... later, to release the memory:
|
| -// AlignedFree(my_array);
|
| -//
|
| -// Or using scoped_ptr:
|
| -//
|
| -// scoped_ptr<float, AlignedFreeDeleter> my_array(
|
| -// static_cast<float*>(AlignedAlloc(size, alignment)));
