Convert a Java object to a Clojure map.
from-java-deepcljmultimethod
Convert a Java object to a Clojure map (converting deeply).
The second argument is a hash map that offers some control over the conversion:
- :add-class -- if true, add :class with the actual class of the object being converted -- this mimics clojure.core/bean.
- :exceptions -- controls how getter exceptions should be handled: * :group -- return an :exceptions hash map in the object that contains all the properties that failed, with their exceptions, * :omit -- ignore exceptions and omit the properties that caused them, * :qualify -- return the exception as :<property>/exception and omit the property itself, * :return -- simply return the exception as the value of the property.
- :omit -- a set of properties (keywords) to omit from the conversion so that unsafe methods are not called (this applies across the whole recursive/deep conversion).

to-javacljmultimethod
Convert Clojure data to an instance of the specified Java class. Several basic types have obvious conversions, but for a hash map reflection is used to set the properties. If the class is an interface, we can't create an instance of it, unless the Clojure map already implements it.
When java.time.Instant is available (Java 8+), we can convert a hash map containing :nano and :epochSecond to Instant, as this is the reverse of Instant->map.
A XMLGregorianCalendar object can be constructed from the following keys :year, :month, :day, :hour, :minute, :second, and :timezone.
