A Java library that abstracts memory and files on disk as an infinitely long array of bits. It also contains a variety of classes to read sequences of bits to make it easier to encode data in the format you want. For example: ``` InfiniteBitArray array = JBitArrays.fileAsBitArray( new File("./demo.bin"), /memory-mapped buffer size in bytes/ 1000 * 1000); array.set(/index to set/ 34483302, /the bit/ true); array.setN(235904, /bits to set/ 31, /from lowest bits of/ 0xDEADBEEF);

CrawlerReader reader = JBitArrays.startReading(array, /starting at index/ 177); boolean firstBit = reader.getNext(); int next17bits = reader.getNextN(17); // returned in lowest bits of int ```
