Subject [jira] Updated: (LANG-411) HashCodeBuilder: expose typed hashing methods
Date Wed, 30 Jun 2010 00:33:50 GMT

     [ https://issues.apache.org/jira/browse/LANG-411?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sean Mickey updated LANG-411:
-----------------------------

    Attachment: ObjectUtils-Patch-Addresses-LANG-411-and-LANG-627.txt
                ObjectUtilsTest-Patch-Adds-Tests-For-Changes-To-Address-LANG-411-and-LANG-627.txt

I have created a patch to ObjectUtils that addresses LANG-411 and LANG-627. It is attached
for review.

I have also created a corresponding patch to ObjectUtilsTest that unit tests the functionality
added in the ObjectUtils patch. It is also attached for review.

I chose this simple set of changes because it lets me get my feet wet with something simple
and straightforward, but that is also a fair amount of work so that it alleviates the load
on some of the old hands.

I hope this is helpful and I look forward to all feedback. Thanks~

> HashCodeBuilder encapsulates the good advice of Joshua Bloch. He details how each java.lang
type should be hashed. I want to use those too ... but without reflection. Please expose those
as static methods:
> hashInt, hashBoolean, etc.
> They should take two parameters: the field value, and the hash multiplier value.
