-------------------------------------
Summary: [C++] Improve buffer creation for typed data
Key: ARROW-3157
URL: https://issues.apache.org/jira/browse/ARROW-3157
Project: Apache Arrow
Issue Type: Improvement
Reporter: Philipp Moritz
While looking into [https://github.com/apache/arrow/pull/2481,] I noticed this
pattern:
{code:java}
const uint8_t* bytes_array = reinterpret_cast<const uint8_t*>(input);
auto buffer = std::make_shared<Buffer>(bytes_array,
sizeof(float)*input_length);{code}
It's not the end of the world but seems a little verbose to me. It would be
great to have something like this:
{code:java}
auto buffer = MakeBuffer<float>(input, input_length);{code}
I couldn't find it, does it already exist somewhere? Any thoughts on the API?
Potentially specializations to make a buffer out of a std::vector<T> would also
be helpful.
