UnsafeByteSequence


java.lang

Class UnsafeByteSequence



  • public class UnsafeByteSequence
    extends Object
    A cheaper ByteArrayOutputStream for internal use. This class is unsynchronized, and returns its internal array if it's the right size. This makes String.getBytes("UTF-8") 10x faster than the baseline non-fast-path implementation instead of 8x faster when using ByteArrayOutputStream. When GC and uncontended synchronization become cheap, we should be able to get rid of this class. In the meantime, if you need to add further API, please try to keep it plug-compatible with ByteArrayOutputStream with an eye to future obsolescence.
