Public Member Functions | |
StringHash () noexcept | |
Construct with zero value. | |
StringHash (const StringHash &rhs) noexcept=default | |
Copy-construct from another hash. | |
StringHash (unsigned value) noexcept | |
Construct with an initial value. | |
StringHash (const char *str) noexcept | |
Construct from a C string. | |
StringHash (const String &str) noexcept | |
Construct from a string. | |
StringHash & | operator= (const StringHash &rhs) noexcept=default |
Assign from another hash. | |
StringHash | operator+ (const StringHash &rhs) const |
Add a hash. | |
StringHash & | operator+= (const StringHash &rhs) |
Add-assign a hash. | |
bool | operator== (const StringHash &rhs) const |
Test for equality with another hash. | |
bool | operator!= (const StringHash &rhs) const |
Test for inequality with another hash. | |
bool | operator< (const StringHash &rhs) const |
Test if less than another hash. | |
bool | operator> (const StringHash &rhs) const |
Test if greater than another hash. | |
operator bool () const | |
Return true if nonzero hash value. | |
unsigned | Value () const |
Return hash value. | |
String | ToString () const |
Return as string. | |
String | Reverse () const |
Return string which has specific hash value. Return first string if many (in order of calculation). Use for debug purposes only. Return empty string if DRY_HASH_DEBUG is off. | |
unsigned | ToHash () const |
Return hash value for HashSet & HashMap. | |
Static Public Member Functions | |
static unsigned | Calculate (const char *str, unsigned hash=0) |
Calculate hash value from a C string. | |
static StringHashRegister * | GetGlobalStringHashRegister () |
Get global StringHashRegister. Use for debug purposes only. Return nullptr if DRY_HASH_DEBUG is off. | |
Static Public Attributes | |
static const StringHash | ZERO |
Zero hash. | |
Private Attributes | |
