OptimizelyJSON for the Java SDK
Describes the OptimizelyJSON object, which the Optimizely Feature Experimentation Java SDK uses to retrieve JSON.
Since statically typed languages lack native support for JSON, the Java SDK uses the OptimizelyJSON object to retrieve JSON in a flexible way.
Version
SDK v3.5 and higher
Methods
You can access JSON representations with the following methods:
Method | Parameters | Description |
|---|---|---|
| none | Returns a string representation of the JSON object |
| none | Returns a map representation of the JSON object: |
| | Returns a specified schema object ( If JSON key is null or empty, it populates your schema object with all JSON key/value pairs. You can retrieve information for a nested member of the JSON data structure by using flattened JSON dot notation. |
The OptimizelyJSON object is defined as follows:
public class OptimizelyJSON { public String toString(); public Map<String,Object> toMap(); public <T> T getValue(@Nullable String jsonKey, Class<T> clazz) throws JsonParseException}Examples
You can easily useOptimizelyJSON object, for example to:
- Get a JSON string by calling the
toStringmethod, or - Retrieve a specified schema from the
OptimizelyJSONobject by calling thegetValuemethod.
The following example shows how to use an OptimizelyJSON object to populate a schema object you declare.
//declare a schema object into which you want to unmarshal OptimizelyJson content:public static class SSub {public string field}public static class SObj {public int field1 public double field2public string field3public SSub field4 }//parse all json key/value pairs into your schema, sObjSObj robj = optlyJSON.getValue(null, SObj.class);//or, parse the specified key/value pair with an integer value Integer rint = optlyJSON.getValue("field1", Integer.class) //or, parse the specified key/value pair with a string valuevar strValue stringSSub rsub = optlyJSON.getValue("field4.field", SSub.class)Updated 17 days ago
