Member functions

Requirements

Header: <allocators>

Namespace: stdext

max_none::allocated

Increments the count of allocated memory blocks.

void allocated(std::size_t _Nx = 1);

Parameters

_Nx
The increment value.

Remarks

This member function does nothing. It is called after each successful call by cache_freelist::allocate to operator new. The argument _Nx is the number of memory blocks in the chunk allocated by operator new.

max_none::deallocated

Decrements the count of allocated memory blocks.

void deallocated(std::size_t _Nx = 1);

Parameters

_Nx
The increment value.

Remarks

The member function does nothing. This member function is called after each call by cache_freelist::deallocate to operator delete. The argument _Nx is the number of memory blocks in the chunk deallocated by operator delete.

max_none::full

Returns a value that specifies whether more memory blocks should be added to the free list.

bool full();

Return Value

This member function always returns true.

Remarks

This member function is called by cache_freelist::deallocate. If the call returns true, deallocate puts the memory block on the free list; if it returns false, deallocate calls operator delete to deallocate the block.

max_none::released

Decrements the count of memory blocks on the free list.

void released();

Remarks

This member function does nothing. The released member function of the current max class is called by cache_freelist::allocate whenever it removes a memory block from the free list.

max_none::saved

Increments the count of memory blocks on the free list.

void saved();

Remarks

This member function does nothing. It is called by cache_freelist::deallocate whenever it puts a memory block on the free list.
