OptimizelyJSON
This topic describes the OptimizelyJSON object which the Optimizely Android SDK uses to retrieve JSON.
Since statically typed languages lack native support for JSON, the Android SDK uses the OptimizelyJSON object to retrieve JSON in a flexible way.
Version
SDK v3.6 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 use the OptimizelyJSON object, for example to:
- Get a JSON string by calling the
toString
method, or - Retrieve a specified schema from the
OptimizelyJSON
object by calling thegetValue
method.
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:
data class SSub(var field: String)
data class SObj(
var field1: Int,
var field2: Double,
var field3: String,
var field4: SSub
)
try {
//parse all json key/value pairs into your schema, sObj
val robj = optlyJSON.getValue(null, SObj::class.java)
//or, parse the specified key/value pair with an integer value
val rint = optlyJSON.getValue("field1", Int::class.java)
//or, parse the specified key/value pair with a string value
val rstr = optlyJSON.getValue("field4.field", String::class.java)
} catch (e: JsonParseException) {
e.printStackTrace()
}
//declare a schema object into which you want to unmarshal OptimizelyJson content:
class SSub {
String field;
}
class SObj {
int field1;
double field2;
String field3;
SSub field4;
}
try {
//parse all json key/value pairs into your schema, sObj
SObj 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 value
String rstr = optlyJSON.getValue("field4.field", String.class);
} catch (JsonParseException e) {
e.printStackTrace();
}
