@cowtowncoder sorry it took me so long to get to it. I just cherry-picked this into 2.14 and it went in clean and the tests passed. I opened a new PR because I'm not really sure how to swing the old PR to the new branch. Is it right for me to target 2.14 instead of master? Will you forward port if you decide to merge? |
This creates two new method on `TokenFilter` which you can override to
decide if empty arrays and objects should be included or excluded. An
override like this, for example, will include all arrays and objects
that were sent empty but strip any arrays or objects that were
*filtered* to be empty:
```
@OverRide
public boolean includeEmptyArray(boolean contentsFiltered) {
return !contentsFiltered;
}
@OverRide
public boolean includeEmptyObject(boolean contentsFiltered) {
return !contentsFiltered;
}
```
The default to preserve backwards compatibility is to always *exclude*
empty objects.
Closes FasterXML#715

Yes, 2.14 is perfect; I do indeed merge forward usually. |

Note: one of top items for me to get merged, not today probably but very soon. Thank you very much for your patience. |

I will add Javadocs, after merge.
