Class JsonSetterAnnotationProcessor

java.lang.Object

com.authlete.common.annotationprocessor.JsonSetterAnnotationProcessor

public class JsonSetterAnnotationProcessor
extends Object

This class is responsible for taking a class and determining whether there are any ambiguous setter methods defined. Then also set the JsonSetter annotation onto the correct setter method.

To determine which is the "correct" setter function we should set the annotation to, we will look up the matching getter and use it's return type and use the setter whose argument matches the getter's return type.

E.g. Given the below object with multiple setters defined:

 
 class AJsonObject
 {
      void setProperty(List<String>) { ... }
      // @JsonSetter would be added here since String[] is this function's argument which matches the getter's return value
      void setProperty(String[]) { ... }
      void String[] getProperty() { ... }
 }
 
 

Using the above example object, the JsonSetter annotation would be added to the `setProperty(String[])` method since its input argument of `String[]` matches the return type of the properties' getter method.
