Detailed Description

Rolling hash function. Allows efficient computation of the hash of a window into a block of data, which can be moved through the data byte by byte.

Member Function Documentation

Add() [1/3]

void FBuzHash::Add ( const uint8 *  Data, uint64  Size  )

inline

Adds an array of bytes to the start of the window.

Add() [2/3]

UE_FORCEINLINE_HINT void FBuzHash::Add ( FMemoryView  View )

inline

Adds an array of bytes to the start of the window.

Add() [3/3]

void FBuzHash::Add ( uint8  X )

inline

Appends a byte to the start of the window and updates the hash.

Get()

UE_FORCEINLINE_HINT uint32 FBuzHash::Get ( ) const

inline

Gets the current hash value.

GetWindowSize()

UE_FORCEINLINE_HINT uint64 FBuzHash::GetWindowSize ( ) const

inline

Gets the size of the window.

Reset()

UE_FORCEINLINE_HINT void FBuzHash::Reset ( )

inline

Reset the state of the hasher.

Sub()

void FBuzHash::Sub ( uint8  X )

inline

Removes a byte from the back of the sliding window and updates the hash.
