[英]How to declare a vector of pointers in Cython?
I want to declare something like that: 我想宣布这样的事情:
cdef vector[Node*] list2node(list my_list):
But Cython gives me this error: 但是Cython给了我这个错误:
cdef vector[Node*] list2node(list my_list):
^
------------------------------------------------------------
mod.pyx:77:20: Expected an identifier or literal
You shouldn't need the *
-- vector[Node]
should generate code for a vector of Node pointers. 你不应该需要
*
- vector[Node]
应该为Node指针的向量生成代码。 Using Cython 0.14.1: 使用Cython 0.14.1:
cdef class Node:
pass
cdef vector[Node] list2node():
pass
cdef vector[int] test_int():
pass
cdef vector[int*] test_intp():
pass
Generates the C++ code: 生成C ++代码:
static PyTypeObject *__pyx_ptype_3foo_Node = 0;
static std::vector<struct __pyx_obj_3foo_Node *> __pyx_f_3foo_list2node(void);
static std::vector<int> __pyx_f_3foo_test_int(void);
static std::vector<int *> __pyx_f_3foo_test_intp(void);
Taking the answer from this SO answer , what you should do is 从这个答案回答 ,你应该做的是
ctypedef Node* Node_ptr
and then use Node_ptr
across your program. 然后在整个程序中使用
Node_ptr
。
