Detailed Description

template<typename TYPE, template< typename > typename DERIVED>
class original::allocatorBase< TYPE, DERIVED >

Interface for other memory allocator implementations.

Template Parameters

TYPE	The type of objects to allocate
DERIVED	CRTP template parameter for derived allocators

Provides common interface and utilities for memory management:

• Type-safe allocation/de-allocation
• Object construction/destruction
• Rebinding support for container needs
• Propagation control for container operations

Propagation traits:

• propagate_on_container_copy_assignment
• propagate_on_container_move_assignment
• propagate_on_container_swap
• propagate_on_container_merge

Member Typedef Documentation

rebind_alloc

template<typename TYPE, template< typename > typename DERIVED>

template<typename O_TYPE>

using original::allocatorBase< TYPE, DERIVED >::rebind_alloc = DERIVED<O_TYPE>

Rebinds allocator to different type.

Template Parameters

O_TYPE

New type to allocate

Constructor & Destructor Documentation

allocatorBase()

template<typename TYPE, template< typename > class DERIVED>

original::allocatorBase< TYPE, DERIVED >::allocatorBase ( )

constexpr

Constructs a new allocatorBase instance.

Performs compile-time validation of the allocated type:

• Ensures TYPE is not void
• Ensures TYPE is a complete type (size > 0)

Member Function Documentation

allocate()

template<typename TYPE, template< typename > typename DERIVED>

virtual TYPE * original::allocatorBase< TYPE, DERIVED >::allocate ( u_integer size )

pure virtual

Allocates raw memory.

Parameters

size	Number of elements to allocate

Returns

Pointer to allocated memory

Implemented in original::allocator< TYPE >, original::allocator< bool >, original::allocator< K_TYPE >, original::allocator< opts >, and original::objPoolAllocator< TYPE >.

construct()

template<typename TYPE, template< typename > typename DERIVED>

template<typename O_TYPE, typename... Args>

void original::allocatorBase< TYPE, DERIVED >::construct	(	O_TYPE *	o_ptr,
		Args &&...	args )

Constructs an object in allocated memory.

Template Parameters

O_TYPE	Type of object to construct
Args	Constructor argument types

Parameters

o_ptr	Pointer to allocated memory
args	Arguments to forward to constructor

deallocate()

template<typename TYPE, template< typename > typename DERIVED>

virtual void original::allocatorBase< TYPE, DERIVED >::deallocate ( TYPE * ptr, u_integer size )

pure virtual

Deallocates memory.

Parameters

ptr	Pointer to memory to free
size	Number of elements originally allocated

Implemented in original::allocator< TYPE >, original::allocator< bool >, original::allocator< K_TYPE >, original::allocator< opts >, and original::objPoolAllocator< TYPE >.

destroy()

template<typename TYPE, template< typename > typename DERIVED>

template<typename O_TYPE>

void original::allocatorBase< TYPE, DERIVED >::destroy ( O_TYPE * o_ptr )

static

Destroys an object without deallocating.

Template Parameters

O_TYPE

Type of object to destroy

Parameters

o_ptr

Pointer to object to destroy
