getAllProperties

public static Map<String,PropertyDescriptor> getAllProperties(GenericType root)
                                                       throws IntrospectionException

A function that returns a Map of all the available properties on a given class including write-only properties. The properties returned is mostly a superset of those returned from the standard JavaBeans Introspector except pure indexed properties are discarded.

Interfaces receive all the properties available in Object. Arrays, Strings and Collections all receive a "length" property. An array's "length" PropertyDescriptor has no read or write methods.

Instead of indexed properties, there may be keyed properties in the map, represented by a KeyedPropertyDescriptor. Arrays, Strings and Lists always have keyed properties with a key type of int.

Because the value returned from a keyed property method may be more specific than the method signature describes (such is often the case with collections), a bean class can contain a special field that indicates what that specific type should be. The signature of this field is as follows: public static final Class ELEMENT_TYPE = <type>.class;.

Returns:

an unmodifiable mapping of property names (Strings) to PropertyDescriptor objects.

Throws:

IntrospectionException
