All Implemented Interfaces:

Closeable, Flushable, Appendable, AutoCloseable

public class SegmentedWriter
extends BufferWriter

Buffers all writes in segments. This is to hold references to strings instead of copying all the characters. This class is not thread safe. Future: If writing to another segmented buffer, the segments could be shared between the two instances. (or arraycopy instead of writing each)
