Detailed Description

Factory for

view_reader. The memory pointed to by view must live longer than the factory or any readers derived from it

Member Function Documentation

open()

virtual std::unique_ptr<reader_base> open ( aio_buffer_pool &  pool, uint64_t  offset = 0, uint64_t  size = reader_base::nosize, size_t  max_buffers = 1  )

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.
