Henri Yandell updated LANG-627:
-------------------------------
Affects Version/s: (was: 3.1)
Fix Version/s: 3.1
> Include a way to explicitly define a hash constant for each primitive type,
> along with the functionality described in LANG-411
> ------------------------------------------------------------------------------------------------------------------------------
>
> Key: LANG-627
> URL: https://issues.apache.org/jira/browse/LANG-627
> Project: Commons Lang
> Issue Type: Improvement
> Components: lang.*
> Reporter: Sean Mickey
> Priority: Minor
> Fix For: 3.1
>
> Original Estimate: 8h
> Remaining Estimate: 8h
>
> Regarding LANG-411, the description mentions 2 parameters for each hash
> operation: the first a parameter to hold the type instance to be hashed, the
> second a hash multiplier.
> Shouldn't there also be a way to define a specific hash constant value as
> well? Joshua Bloch refers to this value as the starting value for "result" in
> his examples and the HashCodeBuilder code maintains an internal field named:
> iTotal for this value. It doesn't seem to make sense to add a parameter to
> the hashing operations for a starting hash constant value, but it probably
> makes sense to add mutators that allow setting this value across any given
> type. For example: setIntHashConstant, setBoolHashConstant,
> setLongHashConstant, etc. Default values could be defined so that explicit
> hash constants are not required.
