def data
  to_h
end

#data=(data) ⇒ Object

Copy values from supplied hash into this MapMessage Converts Ruby types to Java native Data types as follows:

Fixnum   => long
Float    => double
Bignum   => long
true     => boolean
false    => boolean
nil      => null
Otherwise it calls ::to_s on the supplied data type
