Combine()

void Combine

(

HashInt

value

)

Combines the given value with the current state in an ordered way, which means that the effect of multiple calls to Combine does depend on the order of those calls. You can use this function to compute a hash value of a sequence of HashInts when the sequence order is important.

Parameters

[in]

value

A hash value.

CombineUnordered()

void CombineUnordered

(

HashInt

value

)

Combines the given value with the current state in an unordered way, which means that the effect of multiple calls to CombineUnordered doesn't depend on the order of those calls. You can use this function to compute a hash value of a sequence of HashInts when the sequence order shall be irrelevant.

Parameters

[in]

value

A hash value.
