Annotation Type JsonPOJOBuilder

@Target(value={ANNOTATION_TYPE,TYPE})
 @Retention(value=RUNTIME)
public @interface JsonPOJOBuilder

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 JsonDeserialize.builder() property of 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 withPrefix() property.

In addition to configuration using this annotation, note that many other configuration annotations are also applied to Builders, for example JsonIgnoreProperties can be used to ignore "unknown" properties.

Modifier and Type	Optional Element and Description
String	buildMethodName 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.
String	withPrefix 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).

Element Detail

buildMethodName

public abstract String buildMethodName

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".

Default:

"build"

withPrefix

public abstract String withPrefix

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 JsonProperty annotation to indicate "with-methods" (as well as 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.

Default:

"with"
