Is it possible to change the code generation template for equals() and hashCode()?
I would like the generated code to use the Java 7 Objects class for theses methods.
As of release 14.1 of the Ultimate Edition it is possible to customize the Code generation template of equals()/hashCode() without the use of any third party plugin.
Press "Alt + Insert" (Generate...), choose "equals() and hashCode()" and you will be able to select one of the predefined templates or a customized template of your own.
UPDATE: have a look at the answer from @datentyp. Leaving mine for those stuck on the old versions
There are plugins to allow this. Please have a look at this ones:
They are opensource so you can amend them if you need to.
Update: As of version 14.1 this is supported.
Apparently this functionality does not exist.
There is a request for it though, see: http://youtrack.jetbrains.com/issue/IDEA-56007
Yes it is possible, but with some small hack. Locate your idea.jar file in app folder. Look inside and find files like:
- apacheEqualsBuilder3.vm
- apacheHashCodeBuilder3.vm
and other .vm files..
These template files reuse some macros from equalsHelper.vm.
Change these files inside JAR carefully as you like restart app and check result in Idea under
generate->equals() and hashCode()->Template (... three dots on the right)->read only preview on the right side.
I think installing update of Idea may overwrite this JAR with your custom template changes.
It works! Checked in Idea 15. Enjoy. :-)
