class IOP::IOWriter
Sink
class to write received upstream data to external IO
stream.
Contrary to {FileWriter}, this class does not manage attached IO
instance, e.g. it makes no attempt to close it after processing.
### Use case: concatenate two files.
require 'iop/file' io = File.new('output.dat', 'wb') begin ( IOP::FileReader.new('file1.dat') | IOP::IOWriter.new(io) ).process! ( IOP::FileReader.new('file2.dat') | IOP::IOWriter.new(io) ).process! ensure io.close end
