## Class SegmentedStringWriter

- java.lang.Object
- - java.io.Writer
  - - com.fasterxml.jackson.core.io.SegmentedStringWriter

- All Implemented Interfaces:
    Closeable, Flushable, Appendable, AutoCloseable

      public final class SegmentedStringWriter
      extends Writer

  Efficient alternative to `StringWriter`, based on using segmented internal buffer. Initial input buffer is also recyclable.

  This class is most useful when serializing JSON content as a String: if so, instance of this class can be given as the writer to `JsonGenerator`.
