Annotation Interface Decimal


@Documented @Target({METHOD,FIELD}) @Retention(RUNTIME) @Repeatable(List.class) @PropertyMapping(processor=@PropertyMappingAnnotationProcessorRef(type=DecimalProcessor.class,retrieval=CONSTRUCTOR)) public @interface Decimal
Maps a property to a scaled number field in the index, i.e. a numeric field for integer or floating-point values that require a higher precision than doubles but always have roughly the same scale.

Useful for BigDecimal and BigInteger in particular.

      String name
      Returns:
      The name of the index field.
      Default:
      ""
    • decimalScale

      int decimalScale
      Returns:
      How the scale of values should be adjusted before indexing as a fixed-precision integer. A positive decimalScale will shift the decimal point to the right before rounding to the nearest integer and indexing, effectively retaining that many digits after the decimal place in the index. Since numbers are indexed with a fixed number of bits, this increase in precision also means that the maximum value that can be indexed will be smaller. A negative decimalScale will shift the decimal point to the left before rounding to the nearest integer and indexing, effectively setting that many of the smaller digits to zero in the index. Since numbers are indexed with a fixed number of bits, this decrease in precision also means that the maximum value that can be indexed will be larger. By default, two decimals will be used.
      Default:
      2
