ArgumentEncoders class

A set of methods for decoding structured values from a DataSource.

Specifically, these methods decode types that are used by local widgets (q.v. createCoreWidgets).

These methods take a DataSource and a key. The key is a path to the part of the DataSource that the value should be read from. This may identify a map, a list, or a leaf value, depending on the needs of the method.
