All Implemented Interfaces:

Comparable<PropertyDefinition<?>>, Comparator<ValueOrExpression<String>>

public final class ClassPropertyDefinition
extends PropertyDefinition<String>

Class property definition.

A class property definition defines a property whose values represent a Java class. It is possible to restrict the type of java class by specifying "instance of" constraints.

Note that in a client/server environment, the client is probably not capable of validating the Java class (e.g. it will not be able to load it nor have access to the interfaces it is supposed to implement). For this reason, validation is disabled in client applications.

Method Detail

createBuilder

public static ClassPropertyDefinition.Builder createBuilder(AbstractManagedObjectDefinition<?,?> d,
                                                            String propertyName)

Create a class property definition builder.

Parameters:

d - The managed object definition associated with this property definition.

propertyName - The property name.

Returns:

Returns the new class property definition builder.

accept

public <R,P> R accept(PropertyDefinitionVisitor<R,P> v,
                            P p)

Description copied from class: PropertyDefinition

Apply a visitor to this property definition.

Specified by:

accept in class PropertyDefinition<String>

Type Parameters:

R - The return type of the visitor's methods.

P - The type of the additional parameters to the visitor's methods.

Parameters:

v - The property definition visitor.

p - Optional additional visitor parameter.

Returns:

Returns a result as specified by the visitor.

accept

public <R,P> R accept(PropertyValueVisitor<R,P> v,
                            ValueOrExpression<String> value,
                            P p)

Description copied from class: PropertyDefinition

Apply a visitor to a property value associated with this property definition.

Specified by:

accept in class PropertyDefinition<String>

Type Parameters:

R - The return type of the visitor's methods.

P - The type of the additional parameters to the visitor's methods.

Parameters:

v - The property value visitor.

value - The property value.

p - Optional additional visitor parameter.

Returns:

Returns a result as specified by the visitor.

getInstanceOfInterface

public List<String> getInstanceOfInterface()

Get an unmodifiable list of classes which values of this property must implement.

Returns:

Returns an unmodifiable list of classes which values of this property must implement.

loadClass

public <T> Class<? extends T> loadClass(String className,
                                        Class<T> instanceOf)

Validate and load the named class, and cast it to a subclass of the specified class.

Type Parameters:

T - The requested type.

Parameters:

className - The name of the class to validate and load.

instanceOf - The class representing the requested type.

Returns:

Returns the named class cast to a subclass of the specified class.

Throws:

PropertyException - If the named class was invalid, could not be loaded, or did not implement the required interfaces.

ClassCastException - If the referenced class does not implement the requested type.
