Sometimes it's called a "filter", // but that's not a great name for it, since that implies a thing where // some bits pass through, and others are simply ignored. (That would // be a valid example of a transform, of course.) // // While the output is causally related to the input, it's not a // necessarily symmetric or synchronous transformation. For example, // a zlib stream might take multiple plain-text writes(), and then // emit a single compressed chunk some time in the future. // // Here's how this works: // // The Transform stream has all the aspects of the readable and writable // stream classes. When you write(chunk), that calls _write(chunk,cb) // internally, and returns false if there's a lot of pending writes // buffered up. When you call read(), that calls _read(n) until // there's enough pending readable data buffered up. // // In a transform stream, the written data is placed in a buffer. When // _read(n) is called, it transforms the queued up data, calling the // buffered _write cb's as it consumes chunks. If consuming a single // written chunk would result in multiple output chunks, then the first // outputted bit calls the readcb, and subsequent chunks just go into // the read buffer, and will cause it to emit 'readable' if necessary. // // This way, back-pressure is actually determined by the reading side, // since _read has to be called to start processing a new chunk. However, // a pathological inflate type of transform can cause excessive buffering // here. For example, imagine a stream where every byte of input is // interpreted as an integer from 0-255, and then results in that many // bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in // 1kb of data being output. In this case, you could write a very small // amount of input, and end up with a very large amount of output. In // such a pathological inflating mechanism, there'd be no way to tell // the system to stop doing the transform. A single 4MB write could // cause the system to run out of memory. // // However, even in such a pathological case, only a single written chunk // would be consumed, and then the rest would wait (un-transformed) until // the results of the previous transformed chunk were consumed.
