def stmts_from_json(json_in, on_missing_support='handle'):
"""Get a list of Statements from Statement jsons.
In the case of pre-assembled Statements which have `supports` and
`supported_by` lists, the uuids will be replaced with references to
Statement objects from the json, where possible. The method of handling
missing support is controled by the `on_missing_support` key-word argument.
Parameters
----------
json_in : iterable[dict]
A json list containing json dict representations of INDRA Statements,
as produced by the `to_json` methods of subclasses of Statement, or
equivalently by `stmts_to_json`.
on_missing_support : Optional[str]
Handles the behavior when a uuid reference in `supports` or
`supported_by` attribute cannot be resolved. This happens because uuids
can only be linked to Statements contained in the `json_in` list, and
some may be missing if only some of all the Statements from pre-
assembly are contained in the list.
Options:
- *'handle'* : (default) convert unresolved uuids into `Unresolved`
Statement objects.
- *'ignore'* : Simply omit any uuids that cannot be linked to any
Statements in the list.
- *'error'* : Raise an error upon hitting an un-linkable uuid.
Returns
-------
stmts : list[:py:class:`Statement`]
A list of INDRA Statements.
