Jyson maps jython objects to JSON objects according to the following table.

Jython object Implementation type JSON type Example Notes
None org.python.core.Py.None null None=>null
True, False org.python.core.Py.True, org.python.core.Py.False true,false True=>true
int org.python.core.PyInteger number 42=>42
long org.python.core.PyLong number 42L=>42
float org.python.core.PyFloat number 42.0=>42.0
str org.python.core.PyString string 'Hello World!'=>"Hello World!"
dict org.python.core.PyDictionary, org.python.core.PyStringMap object {'hello': 1, 'world': 2}=>{"hello": 1, "world": 2} Only dictionaries with string keys can be encoded, as according to the JSON spec. Any attempt to encode a dictionary with a non-string key will cause a JysonEncodeException. The values in a dictionary can be any JSON encodable type, including tuples, lists and dictionaries.
list org.python.core.PyList array [1, 42, 'Hello world!']=>[1, 42, "Hello world!"] List elements may be of any JSON encodable type, including tuples, lists and dictionaries
tuple org.python.core.PyTuple array (1, 42, 'Hello world!')=>[1, 42, "Hello world!"] Tuple elements may be of any JSON encodable type, including tuples, lists and dictionaries
