Method Details

wrapJavaObject

public static PythonLikeObject wrapJavaObject(Object object)

Wraps object to a PythonLikeObject.

wrapJavaObject

public static PythonLikeObject wrapJavaObject(Object object,
 Map<Object,PythonLikeObject> createdObjectMap)

getPythonLikeType

public static PythonLikeType getPythonLikeType(Class<?> javaClass)

Get the PythonLikeType of a java Class.

convertPythonObjectToJavaType

public static <T> T convertPythonObjectToJavaType(Class<? extends T> type,
 PythonLikeObject object)

Converts a PythonLikeObject to the given type.

loadName

public static void loadName(org.objectweb.asm.MethodVisitor methodVisitor,
 String name)

Loads a String and push it onto the stack

Parameters:

name - The name to load

returnValue
