- All Implemented Interfaces:
PyObjectAdapter
public class ClassicPyObjectAdapter extends ExtensiblePyObjectAdapter
Implements the algorithm originally used inPy.java2py(java.lang.Object)
to adapt objects. Pre-class adapters are added to handle instances of PyObject, PyProxy and null values. Class adapters are added to handle builtin Java classes: String, Integer, Float, Double, Byte, Long, Short, Character, Class and Boolean. An adapter is added to the post-class adapters to handle wrapping arrays properly. Finally, if all of the added adapters can handle an object, it's wrapped in a PyJavaInstance.

adapt
public PyObject adapt(java.lang.Object o)
Description copied from class:ExtensiblePyObjectAdapter
Attempts to adapt o using the preClass, class and postClass adapters. First each of the preClass adapters is asked in the order of addition if they can adapt o. If so, they adapt it. Otherwise, if o.getClass() is equal to one of the classes from the added ClassAdapters, that class adapter is used. Finally, each of the post class adapters are asked in turn if they can adapt o. If so, that adapter handles it. If none can, null is returned.- Specified by:
