Classes

  Type Name Description
Public class CAllocatorInstance This allows smart pointers to free object memory they are holding on to Passing the allocator itself to the free function allows allocation from multiple instances of an allocator and returning memory to the appropriate instance it was allocated from  
Public class CArenaAllocator Allocates from a series of arenas Memory blocks can not be individually deallocated Deleting this allocator will free all allocated memory NOT thread safe (on purpose, for efficiency)  
Public class CHeapRawAllocator Raw memory allocator that allocates memory from the global heap.  
Public class CInstancedRawAllocator Raw memory allocator that keeps a pointer to an allocator instance which is used for allocation.  
Public struct SScriptContainerElement A type which is used to represent a script type that is unknown at compile time.  
Public struct TAllocatorTraits    
Public struct TAllocatorTraitsBase    
Public struct TCanBitwiseRelocate    
Public class TDefaultElementAllocator The indirect allocation policy always allocates the elements indirectly.  
Public class TInlineElementAllocator The inline allocation policy allocates up to a specified number of elements in the same allocation as the container.  

Enums

  Type Name Description
Public enum uLang:: Copyright Epic Games, Inc. All Rights Reserved.  
Public enum uLang::EObserverId Id type for observer pointers.  

Functions

  Type Name Description
Public function ULANG_FORCEINLINE void

operator delete ( void* Memory,
const ::uLang::CHeapRawAllocator& Allocator
)

 Unfortunately, C++ does not have a clean syntax to invoke custom delete operators so this is a bit useless...
