    • performNecessaryPrimitiveTypeConversion

      public static Object performNecessaryPrimitiveTypeConversion(Class<?> expectedType, Object value, boolean avoidReflectException)
      This method is derived from code in org.eclipse.jdt.apt.core. This method is designed to be invoked by the invocation handler and anywhere that requires a AnnotationValue (AnnotationMirror member values and default values from annotation member). Regardless of the path, there are common primitive type conversion that needs to take place. The type conversions respect the type widening and narrowing rules from JLS 5.1.2 and 5.1.2. The only question remains is what is the type of the return value when the type conversion fails? When avoidReflectException is set to true Return false if the expected type is boolean Return numeric 0 for all numeric primitive types and '0' for char Otherwise: Return the value unchanged. In the invocation handler case: The value returned by InvocationHandler.invoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[]) will be converted into the expected type by the Proxy. If the value and the expected type does not agree, and the value is not null, a ClassCastException will be thrown. A NullPointerException will result if the expected type is a primitive type and the value is null. This behavior causes annotation processors a lot of pain and the decision is to not throw such unchecked exception. In the case where a ClassCastException or NullPointerException will be thrown return some dummy value. Otherwise, return the original value. Chosen dummy values: Return false if the expected type is boolean Return numeric 0 for all numeric primitive types and '0' for char This behavior is triggered by setting avoidReflectException to true Note: the new behavior deviates from what's documented in InvocationHandler.invoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[]) and also deviates from Sun's implementation.
      Parameter:
      expectedType - the expected type of the value.
      value - the current value from the annotation instance.
