HashCombine()

uint32 HashCombine ( uint32 A, uint32 C )

inline

Combines two hash values to get a third. Note - this function is not commutative.

This function cannot change for backward compatibility reasons. You may want to choose HashCombineFast for a better in-memory hash combining function.

Here is the caller graph for this function:

HashCombineFast()

uint32 HashCombineFast ( uint32 A, uint32 B )

inline

Combines two hash values to get a third. Note - this function is not commutative.

WARNING! This function is subject to change and should only be used for creating combined hash values which don't leave the running process, e.g. GetTypeHash() overloads.
