Hello, I am new to Kotlin and apologize for my poor English.
I am trying to convert the code snippet below to Kotlin.
However, I am having trouble finding the equivalent of [JsonExtensiondata] in Kotlin.
public class ProofAttribute
{
[JsonProperty("raw")]
public string Raw { get; set; }
/// <summary>
/// ignore structural mapping of other properties
/// </summary>
[JsonExtensionData]
public IDictionary<string, JToken> Rest { get; set; }
}
If you're looking to serialize and deserialize data, consider utilizing the Jackson library. To implement this, make use of the @JsonAnyGetter annotation which can be found in the documentation here: https://github.com/FasterXML/jackson-annotations/wiki/Jackson-Annotations
The
@JsonAnyGetterannotation is used to designate a getter as an "any getter". This getter returns a java.util.Map with additional properties that will be serialized alongside any regular object properties.
For an example, take a look at this code snippet:
class Student {
private Map<String, String> properties;
public Student(){
properties = new HashMap<>();
}
@JsonAnyGetter
public Map<String, String> getProperties(){
return properties;
}
public void add(String property, String value){
properties.put(property, value);
}
}
The HashMap functions similarly to a dictionary with comparable retrieval times and complexities.
In Kotlin, the implementation would look like this:
@get:JsonAnyGetter
val details: Map<String, JsonNode>
