Detailed Description

Exception class Used to wrap Python exceptions so the caller code can handle them transparently

Definition at line 33 of file Exceptions.h.

Constructor & Destructor Documentation

Exception()

Pyston::Exception::Exception

(

)

Constructor The error message is retrieved from the exception thrown inside Python

Note

If there is no error set on the Python side, a generic error will be used instead

The constructor will take care of calling PyErr_clear

Warning

The caller is assumed to own the global interlock!
