Functions

  Type Name Description
Public function Static void

Init ()

 Initializes the CRC lookup table. Must be called before any of the CRC functions are used.
Public function Static uint32

MemCrc32 ( const void* Data,
int32 Length,
uint32 CRC
)

  
Public function Static TEnableIf< sizeof(CharType)!=1, uint32 >::Type

StrCrc32 ( const CharType* Data,
uint32 CRC
)

 String CRC.
Public function Static TEnableIf< sizeof(CharType)==1, uint32 >::Type

StrCrc32 ( const CharType* Data,
uint32 CRC
)

  
Public function Static uint32

TypeCrc32 ( const T& Data,
uint32 CRC
)

 Generates CRC hash of the element

Typedefs

Name Description
MemCrc32Functor Generates CRC hash of the memory area

Constants

Name Description
CRCTable_DEPRECATED DEPRECATED These tables and functions are deprecated because they're using tables and implementations which give values different from what a user of a typical CRC32 algorithm might expect.lookup table with precalculated CRC values
CRCTablesSB8 Lookup table with precalculated CRC values - slicing by 8 implementation
CRCTablesSB8_DEPRECATED Lookup table with precalculated CRC values - slicing by 8 implementation
