A RubyString, which will have Utils.getSchemaFromString(java.lang.String) called on it, and
it will be added.
A RubySchema, which will be added directly. IMPORTANT NOTE: since this API abstracts away from the distinction between Schema/FieldSchema, its important to understand how a Schema is added to another. In this case, the FieldSchema is pulled directly out of the given Schema. Thus, where in Pig a Schema.FieldSchema might be passed around, internally to this class, generally a Schema will be passed around encapsulating it.
A list will create the Schema for a Tuple whose elements will be the elements of the list. Each element will be subjected to the same rules applied here.
A hash in the form of:
{"name:tuple"=>["x:int","y:int,z:int"], "name2:bag"=>["a:chararray"]}
The keys must be a tuple, bag, or map, and the value must be an array.
