Detailed Description

template<typename T>
class llvm::SpecificBumpPtrAllocator< T >

A BumpPtrAllocator that allows only elements of a specific type to be allocated.

This allows calling the destructor in DestroyAll() and when the allocator is destroyed.

Member Function Documentation

Allocate()

template<typename T>

T * llvm::SpecificBumpPtrAllocator< T >::Allocate ( size_t num = 1 )

inline

Allocate space for an array of objects without constructing them.

Definition at line 458 of file Allocator.h.

References T.

DestroyAll()

template<typename T>

void llvm::SpecificBumpPtrAllocator< T >::DestroyAll ( )

inline

Call the destructor of each allocated object and deallocate all but the current slab and reset the current pointer to the beginning of it, freeing all memory allocated so far.

identifyObject()

template<typename T>

std::optional< int64_t > llvm::SpecificBumpPtrAllocator< T >::identifyObject ( const void * Ptr )

inline

Returns

An index uniquely and reproducibly identifying an input pointer Ptr in the given allocator. Returns an empty optional if the pointer is not found in the allocator.
