/**
* 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:
*
* - By default, setters are expected to have names like `withName()` (for property "name");
* override by {@link #withPrefix()} property.
*
*
*
* 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.
