Class HyperLogLogPlusJsonDeserialiser

java.lang.Object

com.fasterxml.jackson.databind.JsonDeserializer<com.clearspring.analytics.stream.cardinality.HyperLogLogPlus>

uk.gov.gchq.gaffer.sketches.clearspring.cardinality.serialisation.json.HyperLogLogPlusJsonDeserialiser

All Implemented Interfaces:

com.fasterxml.jackson.databind.deser.NullValueProvider

@Deprecated
public class HyperLogLogPlusJsonDeserialiser
extends com.fasterxml.jackson.databind.JsonDeserializer<com.clearspring.analytics.stream.cardinality.HyperLogLogPlus>

Deprecated.

A HyperLogLogPlusJsonDeserialiser deserialises HyperLogLogPlus objects. All objects including TypeValue, TypeSubTypeValue, CustomMap and FreqMap are now properly supported. The only stipulation is that the class must included in the fields of the JSON object. This can be done in Java by including the class annotation:

 @JsonTypeInfo(use = JsonTypeInfo.Id.CLASS, property = "class")
 

The object will not be affected if it does not feature a class as this will be ignored when the object is deserialised. Unfortunately, you cannot have arrays of values as offers is not permitted.

NOTE: the toString method is called by the HyperLogLogPlus class when making the offers so you need to ensure that the toString method is overridden by your object.
