Jun created ARROW-2091: -------------------------- Summary: Interacting with arrow/pyarrow in C++ Key: ARROW-2091 URL: https://issues.apache.org/jira/browse/ARROW-2091 Project: Apache Arrow Issue Type: Improvement Reporter: Jun
I've been searching online for a while but cannot figure out how to do this. Please help if this is already a resolved issue. I have a c++/python application that interacts with arrow/pyarrow. I want to write a C++ api that takes python objects directly and operate on them in c++. {code:java} PyObject* process_table(PyObject* table) { // process the arrow table std::shared_ptr<arrow::Table> tablePtr = table; // How? }{code} The problem here is: how do I extract the internal std::shared_ptr<Table> from the PyObject? Unfortunately we are not using cython in our stack, we operate on PyObject * directly in c++. I can easily do this on numpy arrays: {code:java} PyObject * process_array(PyObject* arr) { PyArray_Check(arr); // process the PyArrayObject directly ... }{code} I wonder is there any way to achieve this level of c++ integration without using cython? Thanks! -- This message was sent by Atlassian JIRA (v7.6.3#76005)
