    • Method Detail

      • getClassName

        static java.lang.String getClassName​(javax.lang.model.type.TypeMirror type)
        Gets the fully qualified class name from the given TypeMirror.

        This method is useful when working with annotation processors or other compile-time code analysis tools that deal with type information represented as a TypeMirror.

        Example Usage

         TypeMirror type = processingEnv.getElementUtils().getTypeElement("com.example.MyClass").asType();
 String className = getClassName(type); // returns "com.example.MyClass"
        Parameters:
        type - the type mirror to extract the class name from
        Returns:
        the fully qualified class name as a String

      • loadClass

        static java.lang.Class loadClass​(javax.lang.model.type.TypeMirror type)
        Loads the class represented by the given TypeMirror.

        This method derives the fully qualified class name from the type mirror and delegates to the other loadClass(String) method for class loading. It is particularly useful in annotation processors or compile-time tools where types are primarily accessed via their mirror representations.

        Example Usage

         TypeMirror type = processingEnv.getElementUtils().getTypeElement("com.example.MyClass").asType();
 Class clazz = ClassUtils.loadClass(type); // loads com.example.MyClass
        Parameters:
        type - the type mirror representing the class to load
        Returns:
        the resolved Class, or null if the class cannot be found

      • loadClass

        static java.lang.Class loadClass​(java.lang.String className)
        Loads the class represented by the given fully qualified class name.

        This method attempts to resolve the class using the provided class name and the class loader obtained from ClassUtils. If the class is not found, an attempt is made to resolve it as a nested or inner class by replacing the last dot (.) with a dollar sign ($).

        Example Usage

         Class clazz = ClassUtils.loadClass("com.example.MyClass");
 // If MyClass is an inner class, this may also attempt to load "com.example.My$Class"
        Parameters:
        className - the fully qualified name of the class to load
        Returns:
        the resolved Class, or null if the class cannot be found
