Classes

  Type Name Description
Public class CArchive Abstract archive base class, similar to UE FArchive Assumes same endian on all platforms  
Public class CCRC16 Helper class for computing a 16 bit CRC We are using the CRC-16-CCITT polynomial (0x1021), but are using a bit reversed algorithm akin to CRC32 and CRC64 algorithms which saves one bit shift  
Public class CCRC32 Helper class for computing a 32 bit CRC We are using the CRC-32 polynomial 0x04c11db7 as used by zip, PHP etc., but are using a bit reversed which saves one bit shift  
Public class CCRC64 Helper class for computing a 64 bit CRC We are using the ECMA CRC-64 polynomial 0x42F0E1EBA9EA3693  
Public class CFloatStateCheckOnly Scope guard that asserts the current FP state has the IEEE-compliant settings we expect on entry, but never changes state.  
Public class CFloatStateDoNothing Scope guard that doesn't actually do anything.  
Public class CFloatStateSaveRestore Scope guard that saves current FP state (rounding mode, flush-to-zero etc.) and puts us into fully IEEE compliant mode for the duration of the scope.  
Public class CMath    
Public class CRandomStream Implements a thread-safe random number stream.  
Public class FNull    
Public struct TDisambiguater Used to disambiguate methods that are overloaded for all possible subtypes of a TUnion where the subtypes may not be distinct.  
Public class TEvent Generic event dispatcher.  
Public class TEventRegistrar Registration portion of an TEvent<>.  
Public struct TIsOptional Traits class which tests if a type is optional.  
Public struct TOptional When we have an optional value IsSet() returns true, and GetValue() is meaningful.  
Public class TUnion Represents a type which is the union of several other types; i.e. it can have a value whose type is of any the union's subtypes.
