Package com.fasterxml.jackson.dataformat.csv.impl

Class UTF8Writer

  • All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.Appendable, java.lang.AutoCloseable
    public final class UTF8Writer
extends java.io.Writer
    Efficient UTF-8 backed writer.

    Note: original implementation based on writer from Jackson core package; modified slightly, copied to reduce dependency to impl details.
