Detailed Description

Extends std::allocator interface to provide semantics like operator new and delete.

The class is the wrapper around underlying Alloc class. Alloc provides the std::allocator interface.

Member Function Documentation

template<typename T , class Alloc = CDS_DEFAULT_ALLOCATOR>

template<typename S >

value_type* cds::details::Allocator< T, Alloc >::NewArray	(	size_t	nCount,
		S const &	src
	)

inline

Analogue of operator new T[nCount ].

Each item of array of type T is initialized by parameter src: T( src )

template<typename T , class Alloc = CDS_DEFAULT_ALLOCATOR>

template<typename... S>

value_type* cds::details::Allocator< T, Alloc >::NewBlock	(	size_t	nSize,
		S const &...	src
	)

inline

Allocates block of memory of size at least nSize bytes.

Internally, the block is allocated as an array of void* pointers, then Construct() method is called to initialize T.

Precondition: nSize >= sizeof(T)
