## com.fasterxml.jackson.core.io
Class SegmentedStringWriter

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

All Implemented Interfaces:
  Closeable, Flushable, Appendable

    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`.
