Class JSONAnnotationValueVisitor

  • All Implemented Interfaces:
    javax.lang.model.element.AnnotationValueVisitor<java.lang.StringBuilder,​javax.lang.model.element.ExecutableElement>
    public class JSONAnnotationValueVisitor
extends javax.lang.model.util.SimpleAnnotationValueVisitor6<java.lang.StringBuilder,​javax.lang.model.element.ExecutableElement>
    A visitor implementation for converting AnnotationValue objects into JSON-formatted strings. This class extends SimpleAnnotationValueVisitor6 and is designed to work with Java annotation processing tools to generate JSON representations of annotation values.

    Example Usage

    
 // Example 1: Visiting a simple annotation value
 AnnotationValue value = ...; // e.g., a String, int, or boolean value
 ExecutableElement method = ...; // the method corresponding to the annotation attribute
 StringBuilder jsonBuilder = new StringBuilder();
 JSONAnnotationValueVisitor visitor = new JSONAnnotationValueVisitor(jsonBuilder);
 visitor.visit(value, method); // Result: appends JSON key-value pair to jsonBuilder

 // Example 2: Visiting an array annotation value
 List<? extends AnnotationValue> arrayValues = ...; // list of annotation values
 visitor.visitArray(arrayValues, method); // Result: appends JSON array to jsonBuilder

 // Example 3: Visiting a nested annotation
 AnnotationMirror annotationMirror = ...;
 visitor.visitAnnotation(annotationMirror, method); // Result: appends JSON object to jsonBuilder

    This visitor is typically used during annotation processing to serialize annotation values into a structured JSON format, useful for configuration or metadata generation purposes.
