Whether the reader can benefit from multiple buffers.
If false, calling open with max_buffers larger than min_buffer_usage() offers no benefits.
Reimplemented from reader_factory.
|
overridevirtual |
Creates a reader.
The pool must live longer than the returned reader.
Seekable readers can be opened at any position. If the reader is not seekable, pass an offset of 0 or open will fails.
size can limit the amount of data the reader can returned. Note that a size limit that exceeds the actual size will result in reader_base::get_buffer eventually returning an error.
Implements reader_factory.
