deeply_tracked_allocator< Tracker, RawAllocator > Class Template Reference

Detailed Description

template<class Tracker, class RawAllocator>
class foonathan::memory::deeply_tracked_allocator< Tracker, RawAllocator >

A tracked_allocator that has rebound any BlockAllocator to the corresponding deeply_tracked_block_allocator.

This makes it a deeply tracked allocator.
It replaces each template argument of the given RawAllocator for which is_block_allocator or is_raw_allocator is true with a deeply_tracked_block_allocator.

Member Functions

allocate_node()

void * allocate_node ( std::size_t size, std::size_t alignment )

inherited

Effects:

Calls Tracker::on_node_allocation() and forwards to the allocator. If a growth occurs and the allocator is deeply tracked, also calls Tracker::on_allocator_growth().

Returns:

The result of allocate_node()

try_allocate_node()

void * try_allocate_node ( std::size_t size, std::size_t alignment )

noexceptinherited

Effects:

Calls the composable node allocation function. If allocation was successful, also calls Tracker::on_node_allocation().

Returns:

The result of try_allocate_node().

allocate_array()

void * allocate_array ( std::size_t count, std::size_t size, std::size_t alignment )

inherited

Effects:

Calls Tracker::on_array_allocation() and forwards to the allocator. If a growth occurs and the allocator is deeply tracked, also calls Tracker::on_allocator_growth().

Returns:

The result of allocate_array()

try_allocate_array()

void * try_allocate_array ( std::size_t count, std::size_t size, std::size_t alignment )

noexceptinherited

Effects:

Calls the composable array allocation function. If allocation was succesful, also calls Tracker::on_array_allocation().

Returns:

The result of try_allocate_array().

deallocate_node()

void deallocate_node ( void * ptr, std::size_t size, std::size_t alignment )

noexceptinherited

Effects:

Calls Tracker::on_node_deallocation() and forwards to the allocator's deallocate_node(). If shrinking occurs and the allocator is deeply tracked, also calls Tracker::on_allocator_shrinking().

try_deallocate_node()

bool try_deallocate_node ( void * ptr, std::size_t size, std::size_t alignment )

noexceptinherited

Effects:

Calls the composable node deallocation function. If it was succesful, also calls Tracker::on_node_deallocation().

Returns:

The result of try_deallocate_node().

deallocate_array()

void deallocate_array ( void * ptr, std::size_t count, std::size_t size, std::size_t alignment )

noexceptinherited

Effects:

Calls Tracker::on_array_deallocation() and forwards to the allocator's deallocate_array(). If shrinking occurs and the allocator is deeply tracked, also calls Tracker::on_allocator_shrinking().

try_deallocate_array()

bool try_deallocate_array ( void * ptr, std::size_t count, std::size_t size, std::size_t alignment )

noexceptinherited

Effects:

Calls the composable array deallocation function. If it was succesful, also calls Tracker::on_array_deallocation().

Returns:

The result of try_deallocate_array().

max_node_size()

std::size_t max_node_size ( ) const

inherited

Returns:

The result of the corresponding function on the wrapped allocator.

max_array_size()

std::size_t max_array_size ( ) const

inherited

Returns:

The result of the corresponding function on the wrapped allocator.

max_alignment()

std::size_t max_alignment ( ) const

inherited

Returns:

The result of the corresponding function on the wrapped allocator.

get_allocator() [1/2]

allocator_type & get_allocator ( )

noexceptinherited

Returns:

A (const) reference to the wrapped allocator.

get_allocator() [2/2]

const allocator_type & get_allocator ( ) const

noexceptinherited

Returns:

A (const) reference to the wrapped allocator.

get_tracker() [1/2]

tracker & get_tracker ( )

noexceptinherited

Returns:

A (const) reference to the tracker.

get_tracker() [2/2]

const tracker & get_tracker ( ) const

noexceptinherited
