JSAN.addTo(Collection<E>) would check each element type.
If one element in JSAN could not be converted to E, then it would not be added to collection.
Also JSAN.addTo(Collection<E>, Mapper<Object,E>) and JSAN.addTo(Collection<E>, Class<E>) are available. If an Exception is raised while converting one element, then it would not be added to collection.
