setModelKeys

open fun setModelKeys(@Nullable modelKeys: MutableSet<String>): Unit

Set the attributes in the model that should be rendered by this view. When set, all other model attributes will be ignored. The matching attributes are further narrowed with HttpMessageWriter#canWrite. The matching attributes are processed as follows:

0: nothing is written to the response body.
1: the matching attribute is passed to the writer.
2..N: if the writer supports Map, write all matches; otherwise raise an IllegalStateException.
