我正在尝试将 cpp lib 包装到cython
. 以下是一些细节:
Handle.h
:
class Handle {
public:
// accessors
// mutators
};
class Store {
public:
Handle* lookup(char* handleName);
int update(Handle*);
};
handle.pyx
:
cdef extern from "Handle.h" namespace "xxx":
cdef cppclass Handle:
....
cdef extern from "Handle.h" namespace "xxx":
cdef cppclass Store:
Handle* lookup(char*)
int update(Handle*)
cdef class PyHandle:
cdef Handle* handle
....
cdef class PyStore:
cdef Store* store
def __cinit__(self):
store = ....
def lookup(self, name):
handle = self.store.lookup(name)
pHandle = PyHandle()
pHandle.handle = handle
return pHandle
def update(self, h):
self.store.update(h.handle)
最后一条语句是给我一个错误的说法Cannot convert Python object to 'Handle *'
。我知道我错过了一些简单的东西。如何将Handle*
嵌入在 Python 对象中的那个传递给调用?
