There is a newer version: 2.17.0

package com.fasterxml.jackson.core.util;

/**
 * Add-on interface used to indicate things that may be "blueprint" objects
 * which can not be used as is, but are used for creating usable per-process
 * (serialization, deserialization) instances, using
 * {@link #createInstance} method.
 *
 * Note that some implementations may choose to implement {@link #createInstance}
 * by simply returning 'this': this is acceptable if instances are stateless.
 * 
 * @see DefaultPrettyPrinter
 * 
 * @since 2.1
