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.
StringHashoperator= (const StringHash &rhs) noexcept=default
 Assign from another hash.
StringHash operator+ (const StringHash &rhs) const
 Add a hash.
StringHashoperator+= (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
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 URHO3D_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 StringHashRegisterGetGlobalStringHashRegister ()
 Get global StringHashRegister. Use for debug purposes only. Return nullptr if URHO3D_HASH_DEBUG is off.

Static Public Attributes

static const StringHash ZERO
 Zero hash.

Private Attributes
