6008 // some bits pass through, and others are simply ignored. (That would
6009 // be a valid example of a transform, of course.)
6011 // While the output is causally related to the input, it's not a
6012 // necessarily symmetric or synchronous transformation. For example,
6013 // a zlib stream might take multiple plain-text writes(), and then
6014 // emit a single compressed chunk some time in the future.
6016 // Here's how this works:
6018 // The Transform stream has all the aspects of the readable and writable
6019 // stream classes. When you write(chunk), that calls _write(chunk,cb)
6020 // internally, and returns false if there's a lot of pending writes
6021 // buffered up. When you call read(), that calls _read(n) until
6022 // there's enough pending readable data buffered up.
6024 // In a transform stream, the written data is placed in a buffer. When
6025 // _read(n) is called, it transforms the queued up data, calling the
6026 // buffered _write cb's as it consumes chunks. If consuming a single
6027 // written chunk would result in multiple output chunks, then the first
6028 // outputted bit calls the readcb, and subsequent chunks just go into
6029 // the read buffer, and will cause it to emit 'readable' if necessary.
6031 // This way, back-pressure is actually determined by the reading side,
6032 // since _read has to be called to start processing a new chunk. However,
6033 // a pathological inflate type of transform can cause excessive buffering
6034 // here. For example, imagine a stream where every byte of input is
6035 // interpreted as an integer from
0-
255, and then results in that many
6036 // bytes of output. Writing the
4 bytes {ff,ff,ff,ff} would result in
6037 //
1kb of data being output. In this case, you could write a very small
6038 // amount of input, and end up with a very large amount of output. In
6039 // such a pathological inflating mechanism, there'd be no way to tell
6040 // the system to stop doing the transform. A single
4MB write could
6041 // cause the system to run out of memory.
6043 // However, even in such a pathological case, only a single written chunk
6044 // would be consumed, and then the rest would wait (un-transformed) until
6045 // the results of the previous transformed chunk were consumed.

13438 * These objects are the currency accepted by SJCL's crypto functions.
13442 * Most of our crypto primitives operate on arrays of
4-byte words internally,
13443 * but many of them can take arguments that are not a multiple of
4 bytes.
13444 * This library encodes arrays of bits (whose size need not be a multiple of
8
13445 * bits) as arrays of
32-bit words. The bits are packed, big-endian, into an
13446 * array of words,
32 bits at a time. Since the words are double-precision
13447 * floating point numbers, they fit some extra data. We use this (in a private,
13448 * possibly-changing manner) to encode the number of bits actually present
13449 * in the last word of the array.
13453 * Because bitwise ops clear this out-of-band data, these arrays can be passed
13454 * to ciphers like AES which want arrays of words.
13459 * Array slices in units of bits.
13460 * @param {bitArray} a The array to slice.
13461 * @param {Number} bstart The offset to the start of the slice, in bits.
