nda::mem::leak_check< A >

#include <nda/mem/allocators.hpp>

Detailed Description

template<Allocator A>
class nda::mem::leak_check< A >

Wrap an allocator to check for memory leaks.

It simply keeps track of the memory currently being used by the allocator, i.e. the total memory allocated minus the total memory deallocated, which should never be smaller than zero and should be exactly zero when the allocator is destroyed.

Template Parameters
Anda::mem::Allocator type to wrap.

Constructor & Destructor Documentation

◆ ~leak_check()

template<Allocator A>
nda::mem::leak_check< A >::~leak_check ( )
inline

Destructor that checks for memory leaks.

In debug mode, it aborts the program if there is a memory leak.

Definition at line 491 of file allocators.hpp.

Member Function Documentation

◆ allocate()

template<Allocator A>
blk_t nda::mem::leak_check< A >::allocate ( size_t s)
inline

Allocate memory and update the total memory used.

Parameters
sSize in bytes of the memory to allocate.
Returns
nda::mem::blk_t memory block.

Definition at line 506 of file allocators.hpp.

◆ allocate_zero()

template<Allocator A>
blk_t nda::mem::leak_check< A >::allocate_zero ( size_t s)
inline

Allocate memory, set it to zero and update the total memory used.

Parameters
sSize in bytes of the memory to allocate.
Returns
nda::mem::blk_t memory block.

Definition at line 518 of file allocators.hpp.

◆ deallocate()

template<Allocator A>
void nda::mem::leak_check< A >::deallocate ( blk_t b)
inlinenoexcept

Deallocate memory and update the total memory used.

In debug mode, it aborts the program if the total memory used is smaller than zero.

Parameters
bnda::mem::blk_t memory block to deallocate.

Definition at line 529 of file allocators.hpp.

◆ empty()

template<Allocator A>
bool nda::mem::leak_check< A >::empty ( ) const
inlinenodiscard

Check if the base allocator is empty.

Returns
True if no memory is currently being used.

Definition at line 544 of file allocators.hpp.

◆ get_memory_used()

template<Allocator A>
long nda::mem::leak_check< A >::get_memory_used ( ) const
inlinenodiscardnoexcept

Get the total memory used by the base allocator.

Returns
The size of the memory which has been allocated and not yet deallocated.

Definition at line 558 of file allocators.hpp.

◆ owns()

template<Allocator A>
bool nda::mem::leak_check< A >::owns ( blk_t b) const
inlinenodiscardnoexcept

Check if a given nda::mem::blk_t memory block is owned by the base allocator.

Parameters
bnda::mem::blk_t memory block.
Returns
True if the base allocator owns the memory block.
