libpython-clj.python.protocols
Protocols to help generalize the python bindings. There is a clear distinction made between building a bridging type and thus allowing communication between the two systems and building a complete copy of the datastructure of one system in another. Generic objects must only bridge but if we know more about the object (like it implements java.util.Map) then we can implement either a bridge or a copy.
Atomic objects:
- numbers
- booleans
- strings-convertible things like strings, keywords, symbols
Standard containers:
- list
- map
- set
- tuple (persistent vector of length less than 8)

PBridgeToJVMcljprotocol
as-jvmclj
(as-jvm item options)Return a pyobject implementation that wraps the python object.
Return a pyobject implementation that wraps the python object.
PBridgeToPythoncljprotocol
as-pythonclj
(as-python item options)Aside from atom types, this means the object represented by a zero copy python mirror. May return nil. This convertible to pointers get converted to numpy implementations that share the backing store.

Return a keyword that describes the python datatype of this object.
python-obj-iteratorcljmultimethod
Given a python object, produce an iterator. Python is fairly confused about what an iterator is or does, so some things require iteritems and some things require calling iter.
