Remove Null Nodes

[vasdevdua]

If any node in json is null, is there any way we can remove that node using this library? Can we override Configuration in any way to remove null nodes?

If not, can we overrride Configuration in a way that instead of defaulting path to null using DEFAULT_PATH_LEAF_TO_NULL, can we replace these strings by empty String and not null.

This feature must be provided by the actual json provider. I can only tell you my experiences with the Jackson API. Here there are options for the renderer to prevent writing null values or empty arrays. For writing one object with this option, I use a patch to avoid printing empty values or arrays. I currently build a pull request to fix that.
