|
|
// reading from disk.
|
|
//
|
|
// This is useful if we're piping one network stream to another. If the stream
|
|
// we're piping to can't consume data as quickly as the one we're consuming
|
|
// from then large quantities of data may be held in memory. Instead the read
|
|
// stream can be passed to this method, the data will then be held on disk
|
|
// rather than in memory and will be cleaned up once it has been consumed.
