Detailed Description

template<typename T, typename AllocatorBase = std::allocator<T>>
class Vdf_DefaultInitAllocator< T, AllocatorBase >

Vdf_DefaultInitAllocator

This allocator intercepts value initialization and turns it into default initialization. It's primary purpose is for use on containers, such as std::vector, that are first resized and then immediately filled with elements. Without the use of this allocator, the resize would value-initialize every element before immediately overwriting the element when it's filled in.

Member Function Documentation

template<typename T , typename AllocatorBase = std::allocator<T>>

template<typename U >

void Vdf_DefaultInitAllocator< T, AllocatorBase >::construct ( U *  ptr )

inlinenoexcept

Value initializing construction. This method instead default initializes instances of U.

Definition at line 46 of file defaultInitAllocator.h.

template<typename T , typename AllocatorBase = std::allocator<T>>

template<typename U , typename... Args>

void Vdf_DefaultInitAllocator< T, AllocatorBase >::construct ( U *  ptr, Args &&...  args  )

inline

Construction with custom constructor arguments. This method simply forwards any arguments to the U constructor.
