@Target([AnnotationTarget.FUNCTION, AnnotationTarget.PROPERTY_GETTER, AnnotationTarget.PROPERTY_SETTER, AnnotationTarget.FIELD, AnnotationTarget.VALUE_PARAMETER, AnnotationTarget.ANNOTATION_CLASS]) class NumberFormat
Declares that a field or method parameter should be formatted as a number.
Supports formatting by style or custom pattern string. Can be applied to any JDK java.lang.Number type.
For style-based formatting, set the #style attribute to be the desired Style. For custom formatting, set the #pattern attribute to be the number pattern, such as #, ###.##.
Each attribute is mutually exclusive, so only set one attribute per annotation instance (the one most convenient one for your formatting needs). When the #pattern attribute is specified, it takes precedence over the #style attribute. When no annotation attributes are specified, the default format applied is style-based for either number of currency, depending on the annotated field or method parameter type.
