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.
