Subject [jira] [Commented] (THRIFT-4177) Java compiler produces deep copy constructor that could make shallow copy instead
Date Tue, 18 Apr 2017 16:57:41 GMT

    [ https://issues.apache.org/jira/browse/THRIFT-4177?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15973063#comment-15973063

James E. King, III commented on THRIFT-4177:
--------------------------------------------

I just linked a number of issues in the backlog, some already done and some not, to this issue.
It looks like there has been a desire to have a deep copy mechanism for a long time.
Folks who use Java more should comment on this PR.

> Java compiler produces deep copy constructor that makes shallow copies for referenced
objects from collections when they are defined after the root object in the thrift file.
> For example, consider following thrift file:
> struct Foo {
> 1: optional list<Bar> bars,
> }
> struct Bar {
> 1: optional string value,
> }
> new Foo().deepCopy() will produce a copy of Foo with a copy of a list that reference
the same Bar object.
