| * >>> Math.uuid(15) // 15 character ID (default base=62) | |
| * "VcydxgltxrVZSTV" | |
| * | |
| * // Two arguments - returns ID of the specified length, and radix. | |
| * // (Radix must be <= 62) | |
| * >>> Math.uuid(8, 2) // 8 character ID (base=2) | |
| * "01001010" | |

| // a transform stream is a readable/writable stream where you do | |
| // something with the data. 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. | |
