Jackson Data Binding Source Code

Jackson is "the Java JSON library" or "the best JSON parser for Java". Or simply as "JSON for Java".

  • Jackson Data Binding module allows you to converts JSON to and from POJO (Plain Old Java Object) using property accessor or using annotations.
  • Jackson Databind Source Code files are provided in the source packge (jackson-databind-2.14.0-sources.jar). You can download it at Jackson Maven Website.

    package com.fasterxml.jackson.databind.annotation;
    import java.lang.annotation.*;
     * Annotation used to configure details of a Builder class:
     * instances of which are used as Builders for deserialized
     * POJO values, instead of POJOs being instantiated using
     * constructors or factory methods.
     * Note that this annotation is NOT used to define what is
     * the Builder class for a POJO: rather, this is determined
     * by {@link JsonDeserialize#builder} property of {@link JsonDeserialize}.
     * Annotation is typically used if the naming convention
     * of a Builder class is different from defaults:
     * <li>By default, setters are expected to have names like `withName()` (for property "name");
     *     override by {@link #withPrefix()} property.
     *  </li>
     * </ul>
     * In addition to configuration using this annotation, note that many other configuration
     * annotations are also applied to Builders, for example
     * {@link com.fasterxml.jackson.annotation.JsonIgnoreProperties} can be used to ignore
     * "unknown" properties.

         * @since 2.9
        public final static String DEFAULT_WITH_PREFIX = "with";
         * Property to use for re-defining which zero-argument method
         * is considered the actual "build-method": method called after
         * all data has been bound, and the actual instance needs to
         * be instantiated.
         * Default value is "build".
        public String buildMethodName() default DEFAULT_BUILD_METHOD;
         * Property used for (re)defining name prefix to use for
         * auto-detecting "with-methods": methods that are similar to
         * "set-methods" (in that they take an argument), but that
         * may also return the new builder instance to use
         * (which may be 'this', or a new modified builder instance).
         * Note that in addition to this prefix, it is also possible
         * to use {@link com.fasterxml.jackson.annotation.JsonProperty}
         * annotation to indicate "with-methods" (as well as
         * {@link com.fasterxml.jackson.annotation.JsonSetter}).
         * Default value is "with", so that method named "withValue()"
         * would be used for binding JSON property "value" (using type
         * indicated by the argument; or one defined with annotations.
        public String withPrefix() default DEFAULT_WITH_PREFIX;
        /* Helper classes
         * Simple value container for containing values read from
         * {@link JsonPOJOBuilder} annotation instance.
