Detailed Description

32-bit hash value for a string.

Member Function Documentation

Reverse()

ea::string Urho3D::StringHash::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.

Value()

unsigned Urho3D::StringHash::Value ( ) const

inline

Return hash value.
