Class OrderedSetSerializer<T>

java.lang.Object
com.fasterxml.jackson.databind.JsonSerializer<Set<T>>
io.fliqa.client.interledger.serializer.OrderedSetSerializer<T>
Type Parameters:
T - the type of elements contained in the set to be serialized
All Implemented Interfaces:
com.fasterxml.jackson.databind.jsonFormatVisitors.JsonFormatVisitable
public class OrderedSetSerializer<T> extends com.fasterxml.jackson.databind.JsonSerializer<Set<T>>
A custom serializer for Set collections that serializes the elements in a deterministic order based on their string representations.

The OrderedSetSerializer ensures that the serialization output for a Set is consistent irrespective of the initial ordering of the elements within the set. It accomplishes this by converting each element in the set to its toString() representation, sorting these string representations in natural order, and then writing them as a JSON array.

This serializer is useful in scenarios where consistent JSON output is required, such as when generating hashes, for debugging purposes, or for API clients requiring deterministic outputs for identical data sets.
