Overview

Adapts any Ruby object that responds to #read into the stream interface SFML's loaders expect, so resources can be loaded from something other than a filesystem path (e.g. an in-memory StringIO, or a custom source).

Constructor Details

#new(io) ⇒ InputStream

Wraps a Ruby object that responds to #read (and ideally +#seek+/+#tell+ or #pos, and #size or #length) so it can be passed anywhere the library accepts a stream-based data source.

Raises:

  • (ArgumentError) —

    if io does not respond to #read
