Access dynamic values from the custom PropertyDrawer of a ScriptableObject

Hi there,

I have a ScriptableObject A that intends to capture dynamically a list of parameter values from the inspector. Here is an illustration of what I whant to do : I have one instance of this ScriptableObject A, that represents a set of three parameters : a float (speed), a boolean (isActive) and a Vector3 (initPosition). Each element of the array is an instance of a Parameter, which consists in a variable Name (string) and a variable Type (another ScriptableObject).

Then, in another class B, I declare a public variable "customParams" of type A, and drag and drop this ScriptableObject to obtain the following in the inspector :

To do that, I made a custom PropertDrawer on my class A, that loops over the parameters, and displays the appropriate field to fill. Here is some code :

 public class ADrawer : PropertyDrawer
 {
    private Parameter[] parameters = null;
    private object[] values;
 
    public override float GetPropertyHeight(SerializedProperty property, GUIContent label) {
 
         float height = EditorGUIUtility.singleLineHeight + EditorGUIUtility.standardVerticalSpacing;
         A myParams = property.objectReferenceValue as System.Object as A;
         if (myParams != null) {
             parameters = myParams.parameters;
             height += parameters.Length * (EditorGUIUtility.singleLineHeight + EditorGUIUtility.standardVerticalSpacing);
         }
         return height;
     }
 
     public override void OnGUI(Rect position, SerializedProperty property, GUIContent label) {
 
         EditorGUI.BeginProperty(position, label, property);
 
         EditorGUI.PropertyField(position, property, label, true);
 
         if (parameters != null) {
             int prevIndent = EditorGUI.indentLevel;
             Rect indentedPosition = EditorGUI.IndentedRect(position);
             EditorGUI.indentLevel += 1;
             values = new object[parameters.Length];
             int i = 0;
             foreach (Parameter p in parameters) {
                 //Parameter label
                 Rect paramLabelPosition = new Rect(indentedPosition.x, position.y + ((i + 1) * (EditorGUIUtility.singleLineHeight + EditorGUIUtility.standardVerticalSpacing)), EditorGUIUtility.labelWidth, EditorGUIUtility.singleLineHeight);
                 EditorGUI.LabelField(paramLabelPosition, p.GetInspectorName());
 
                 //Parameter value
                 Rect valueRect = new Rect(paramLabelPosition.x + paramLabelPosition.width, paramLabelPosition.y, indentedPosition.width - paramLabelPosition.width, EditorGUIUtility.singleLineHeight);
                 Type type = p.type.FindType();
                 values[i] = p.type.DrawPropertyField(valueRect);
                 i++;
             }
             behaviour.SetParameters(parameters, values);
             EditorGUI.indentLevel = prevIndent;
         }
         EditorGUI.EndProperty();
     }

My question is simple : how can I access all the array values from, let's say, a custom PropertyDrawer of B, or even any other class?

Thanks!
