Detailed Description

template<class T, size_t Align = AlignOf<T>::Alignment>
class llvm::ArrayRecycler< T, Align >

Recycle small arrays allocated from a BumpPtrAllocator.

Arrays are allocated in a small number of fixed sizes. For each supported array size, the ArrayRecycler keeps a free list of available arrays.

template<class AllocatorType >

T* llvm::ArrayRecycler< T, Align >::allocate ( Capacity  Cap, AllocatorType &  Allocator  )

inline

Allocate an array of at least the requested capacity.

Return an existing recycled array, or allocate one from Allocator if none are available for recycling.

template<class AllocatorType >

void llvm::ArrayRecycler< T, Align >::clear ( AllocatorType &  Allocator )

inline

Release all the tracked allocations to the allocator. The recycler must be free of any tracked allocations before being deleted.

template<class T, size_t Align = AlignOf<T>::Alignment>

void llvm::ArrayRecycler< T, Align >::clear ( BumpPtrAllocator &  )

inline

Special case for BumpPtrAllocator which has an empty Deallocate() function.

There is no need to traverse the free lists, pulling all the objects into cache.

Definition at line 114 of file ArrayRecycler.h.

template<class T, size_t Align = AlignOf<T>::Alignment>

void llvm::ArrayRecycler< T, Align >::deallocate ( Capacity  Cap, T *  Ptr  )

inline

Deallocate an array with the specified Capacity.

Cap must be the same capacity that was given to allocate().
