public interface MapWriter
extends MapSerializable, NavigableObject, org.noggit.JSONWriter.Writable

Use this class to push all entries of a Map into an output. This avoids creating map instances and is supposed to be memory efficient. If the entries are primitives, unnecessary boxing is also avoided.
