    All Methods Static Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `static Accessor` | `accessor(String nestedPropertyName)` Compiles an accessor that can be used for fast access for the nested property of the objects of a given class.
    `static Object` | `getProperty(Object object, String nestedPropertyName)` Returns object property using JavaBean-compatible introspection with one addition - a property can be a dot-separated property name path.
    `static void` | `setProperty(Object object, String nestedPropertyName, Object value)` Sets object property using JavaBean-compatible introspection with one addition - a property can be a dot-separated property name path.

                                    throws CayenneRuntimeException

    - #### setProperty

          public static void setProperty(Object object,
                                         String nestedPropertyName,

                                  throws CayenneRuntimeException

      Sets object property using JavaBean-compatible introspection with one addition - a property can be a dot-separated property name path. Before setting a value attempts to convert it to a type compatible with the object property. Automatic conversion is supported between strings and basic types like numbers or primitives.
