Getting keys from HashMap

[Ajay Bhat <a....@gmail.com>]

Hi,

Is there any way to get the keys as a ArrayList from HashMap in
org.apache.pivot.collections.HashMap?

In java.util.TreeMap we would just use keySet() function. Is there anything
similar in Pivot?

Thanks,
Ajay Bhat

Hi,
this is the related issue: https://issues.apache.org/jira/browse/PIVOT-799
be free to put some comment/request/patch there ...

Note that there is even the package
org.apache.pivot.collections.adapter to transform Pivot Collections
to/from Java Collections.
Take a look and tell us if something is still missing.

Bye

Hi Ajay,
   No there isn't such a method. Wouldn't be too hard to do if you want to tackle it. I believe there is an existing issue about adding methods to Pivot Collections to bring them more in line with the Java ones.
