## Detailed Description

Abstract class to represent the output of ak.to_buffers. In Python, this would be a dict of NumPy arrays.

## Member Function Documentation

## ◆ copy_buffer()

virtual void copy_buffer | ( | const std::string & | name,
|  | const void * | source,
|  | int64_t | num_bytes
| ) |  |
| pure virtual

Copy data at `source` with `num_bytes` into the BuffersContainer with `name`.

In Python, this allocates a NumPy array and copies data into it.

## ◆ empty_buffer()

virtual void * empty_buffer | ( | const std::string & | name,
|  | int64_t | num_bytes
| ) |  |
| pure virtual

## ◆ full_buffer()

virtual void full_buffer | ( | const std::string & | name,
|  | int64_t | length,
|  | int64_t | value,
|  | const std::string & | dtype
| ) |  |
| pure virtual

Create an array initialized to a given fill value.
