class AllocatorBase

Declaration

template <typename DerivedT>
class AllocatorBase { /* full declaration omitted */ };

Description

CRTP base class providing obvious overloads for the core \c Allocate() methods of LLVM-style allocators. This base class both documents the full public interface exposed by all LLVM-style allocators, and redirects all of the overloads to a single core set of methods which the derived class must define.

Method Overview

• public void * Allocate(size_t Size, size_t Alignment)
• public template <typename T>T * Allocate(size_t Num = 1)
• public void Deallocate(const void * Ptr, size_t Size, size_t Alignment)
• public template <typename T>std::enable_if_t<!std::is_same<std::remove_cv_t<T>, void>::value, void> Deallocate(T * Ptr, size_t Num = 1)

Methods

¶void* Allocate(size_t Size, size_t Alignment)

Description

Allocate \a Size bytes of \a Alignment aligned memory. This method must be implemented by \c DerivedT.

Declared at: llvm/include/llvm/Support/AllocatorBase.h:38

Parameters

size_t Size

size_t Alignment

¶template <typename T>
T* Allocate(size_t Num = 1)

Description

Allocate space for a sequence of objects without constructing them.

Parameters

size_t Num = 1

¶void Deallocate(const void* Ptr,
                size_t Size,
                size_t Alignment)

Description

Deallocate \a Ptr to \a Size bytes of memory allocated by this allocator.

Declared at: llvm/include/llvm/Support/AllocatorBase.h:52
