threshold_segregatable< RawAllocator > Class Template Reference

Detailed Description

template<class RawAllocator>
class foonathan::memory::threshold_segregatable< RawAllocator >

A Segregatable that allocates until a maximum size.

Typedefs
using	allocator_type = typename allocator_traits< RawAllocator >::allocator_type

Member Functions
	threshold_segregatable (std::size_t max_size, allocator_type alloc=allocator_type())
bool	use_allocate_node (std::size_t size, std::size_t) noexcept
bool	use_allocate_array (std::size_t count, std::size_t size, std::size_t) noexcept

const allocator_type &	get_allocator () const noexcept

Constructors

threshold_segregatable()

threshold_segregatable ( std::size_t  max_size, allocator_type  alloc = allocator_type()  )

explicit

Effects:

Creates it by passing the maximum size it will allocate and the allocator it uses.

Member Functions

use_allocate_node()

bool use_allocate_node ( std::size_t  size, std::size_t    )

noexcept

Returns:

true if size is less then or equal to the maximum size, false otherwise.

Note

A return value of true means that the allocator will be used for the allocation.

use_allocate_array()

bool use_allocate_array ( std::size_t  count, std::size_t  size, std::size_t    )

noexcept

Returns:

true if count * size is less then or equal to the maximum size, false otherwise.

Note

A return value of true means that the allocator will be used for the allocation.

get_allocator() [1/2]

allocator_type & get_allocator ( )

noexcept

Returns:

A reference to the allocator it owns.

get_allocator() [2/2]

const allocator_type & get_allocator ( ) const

noexcept

Returns:

A reference to the allocator it owns.
