All Implemented Interfaces:
com.fasterxml.jackson.databind.jsonFormatVisitors.JsonFormatVisitable
@Immutable class WicaDoubleArraySerializer extends com.fasterxml.jackson.databind.JsonSerializer<double[]>
Provides a means of serializing objects of type double[] in such a way that a configurable number of digits appear after the decimal point.

This class works in conjunction with Jackson library module class with whom it must be registered.

      WicaDoubleArraySerializer(int numericScale)
      Constructs a new custom serializer for double arrays.

      The serializer generates a string representation with the specified numeric scale (that's to say with the specified number of digits after the decimal point).

      Where the numeric scale forces rounding, then a RoundingMode.HALF_UP strategy is implemented.

      The JSON generator associated with this serializer can be configured to determine whether this serializer writes special values NaN and Infinity as numbers or strings.

      Parameters:
      numericScale - a positive number specifying the number of digits to appear after the decimal point in the serialized representation.
      Throws:
      IllegalArgumentException - if the requested numeric scale is negative.

      public void serialize(double[] values, com.fasterxml.jackson.core.JsonGenerator gen, com.fasterxml.jackson.databind.SerializerProvider serializers) throws IOException
      Serialize the Double Array.
      Specified by:
      serialize in class com.fasterxml.jackson.databind.JsonSerializer<double[]>
      Parameters:
      values - the array of values to be serialized.
      gen - reference to a Java generator object that provides methods for generating the output string.
      serializers - reference to a serializer provider (not needed by this implementation)
      Throws:
      IOException
