Member Function Documentation

CanFitEntry()

bool FGrowableMallocChunk::CanFitEntry ( uint32 Size, uint32 Alignment )

inline

Check free list for an entry big enough to fit the requested Size with Alignment

Parameters

Size	- allocation size
Alignment	- allocation alignment

Returns

true if available entry was found

Definition at line 170 of file GenericGrowableAllocator.h.

Here is the call graph for this function:

CreateAllocationStruct()

virtual FGrowableAllocationBase * FGrowableMallocChunk::CreateAllocationStruct ( )

pure virtual

Creates an implementation specific subclass of FGrowableAllocationBase. Does not need to be initialized (see InitializeAllocationStruct)

CreateInternalMemory()

virtual uint64 FGrowableMallocChunk::CreateInternalMemory ( uint64 Size )

pure virtual

Lets the implementation allocate the backing memory for the chunk

Implementation needs to pause LLM tracking for ELLMTracker::Default if it's allocating from an allocator that tracks via ELLMTracker::Default

Parameters

Size	Minimum size needed for this allocation. The implementation will likely allocate more, and return that amount

Returns

The actual size of the chunk that was allocated (could be much larger than Size)

Here is the caller graph for this function:

Destroy()

void FGrowableMallocChunk::Destroy ( )

inline

Definition at line 158 of file GenericGrowableAllocator.h.

Here is the call graph for this function:

DestroyAllocationStruct()

virtual void FGrowableMallocChunk::DestroyAllocationStruct ( FGrowableAllocationBase * Allocation )

inlinevirtual

Destroys the implemtnation object. By default, just deletes it

Definition at line 108 of file GenericGrowableAllocator.h.

DestroyInternalMemory()

virtual void FGrowableMallocChunk::DestroyInternalMemory ( )

pure virtual

Destroys the backing memory for the chunk

Implementation needs to pause LLM tracking for ELLMTracker::Default if it's allocating from an allocator that tracks via ELLMTracker::Default

Here is the caller graph for this function:

DoesChunkContainAddress()

virtual bool FGrowableMallocChunk::DoesChunkContainAddress ( const void * Address )

pure virtual

Queries the implementation if the given address came from this chunk

DoesChunkContainAllocation()

virtual bool FGrowableMallocChunk::DoesChunkContainAllocation ( const FGrowableAllocationBase * Allocation )

pure virtual

Queries the implementation if the given allocation came from this chunk

Free()

bool FGrowableMallocChunk::Free ( FGrowableAllocationBase * Memory )

inline

Definition at line 283 of file GenericGrowableAllocator.h.

Here is the call graph for this function:

GetAddressForTracking()

virtual void * FGrowableMallocChunk::GetAddressForTracking ( uint32 Offset )

pure virtual

GetAllocationInfo()

void FGrowableMallocChunk::GetAllocationInfo ( uint64 & Used, uint64 & Free )

inline

Definition at line 358 of file GenericGrowableAllocator.h.

Initialize()

void FGrowableMallocChunk::Initialize ( )

inline

Definition at line 142 of file GenericGrowableAllocator.h.

Here is the call graph for this function:

InitializeAllocationStruct()

virtual void FGrowableMallocChunk::InitializeAllocationStruct ( FGrowableAllocationBase * Allocation )

pure virtual

Lets the implementation fill in any specific fields of the allocation struct after the base fields are set up

IsEmpty()

bool FGrowableMallocChunk::IsEmpty ( )

inline

Returns

true if this chunk has no used memory

Definition at line 209 of file GenericGrowableAllocator.h.

Malloc()

FGrowableAllocationBase * FGrowableMallocChunk::Malloc ( uint32 Size, uint32 Alignment, uint32 MinAllocationSize, int32 OwnerType )

inline

Definition at line 214 of file GenericGrowableAllocator.h.

Here is the call graph for this function:

ShowFullAllocationList()

void FGrowableMallocChunk::ShowFullAllocationList ( )

inline

Definition at line 365 of file GenericGrowableAllocator.h.
