deeply_tracked_allocator< Tracker, RawAllocator > Class Template Reference
Adapters and Wrappers

## 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
| ) |  |

noexcept inherited

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
| ) |  |

noexcept inherited

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
| ) |  |

noexcept inherited

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
| ) |  |

noexcept inherited

  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
| ) |  |

noexcept inherited

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
| ) |  |

noexcept inherited

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 | ( |  | ) |

noexcept inherited

Returns:
  A (`const`) reference to the wrapped allocator.

## get_allocator() [2/2]
