Annotation Type Format
-
@Retention(RUNTIME) @Inherited @Target({FIELD,METHOD,ANNOTATION_TYPE}) public @interface Format
Indicates that a parsed value is formatted and must be parsed before being assigned.The
Conversion
type assigned to this field will depend on its type.Multiple format masks can be tried for a single value.
When reading from this value (for writing to a given output), the first mask declared in
formats()
will be used to produce its String representation.The
options()
is an optional configuration, with properties and values separated by =.. Each property will be used configure the underlying formatter. For example, if the parsed value is a BigDecimal, and the format is '#0,00', the decimal separator must be set to ','. To specify this using theoptions()
annotation, use:- formats="#0,00", options="decimalSeparator=,".
- The "decimalSeparator" property will be used to identify which method in DecimalFormat to invoke. In this case, the method "setDecimalSeparator", with the value on the right hand side of the = operator
