#include <Dry/Math/StringHash.h>

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
unsigned	value_
	Hash value.
