Class RollingCharBuffer

  • public final class RollingCharBuffer
    extends Object
    Acts like a forever growing char[] as you read characters into it from the provided reader, but internally it uses a circular buffer to only hold the characters that haven't been freed yet. This is like a PushbackReader, except you don't have to specify up-front the max size of the buffer, but you do have to periodically call freeBefore(int).
