Class ExtensionSupport

java.lang.Object

org.coliper.ibean.proxy.ExtensionSupport

public class ExtensionSupport
extends Object

Bundles an ExtensionHandler with its supported interfaces. This tuple is then used as a configuration element for creating and customizing IBeanFactorys. See ExtensionHandler for a general description of the ProxyIBeanFactory extension concept. See ProxyIBeanFactory.Builder.withInterfaceSupport(ExtensionSupport) for where and how to use ExtensionSupport. ExtensionSupport instances are created via constructor ExtensionSupport(Class, Class, boolean) and are then immutable.

Constructor and Description
ExtensionSupport(Class<?> supportedInterface, Class<? extends ExtensionHandler> handlerType, boolean handlerStateful) Creates a new immutable ExtensionSupport.

Method Summary

Modifier and Type	Method and Description
boolean	handlerStateful() Returns true if the handler is stateful and needs to have an individual instance per IBean object.
Class<? extends ExtensionHandler>	handlerType() Provides the ExtensionHandler implementation responsible for the supported interface.
Class<?>	supportedInterface() Provides the interface that is covered by the corresponding handler.
List<Class<?>>	supportedInterfaceAndSuperInterfaces() Returns the supportedInterface() together with all sub-interfaces of that interface.

Constructor Detail

ExtensionSupport

public ExtensionSupport(Class<?> supportedInterface,
                        Class<? extends ExtensionHandler> handlerType,
                        boolean handlerStateful)

Creates a new immutable ExtensionSupport.

Parameters:

supportedInterface - specifies the extension interface supported by the ExtensionHandler. Must be a Java interface type.

handlerType - the ExtensionHandler type responsible for intercepting IBean calls to the extension interface. Must be a sublcass of ExtensionHandler.

handlerStateful - specifies if the handler is stateful or stateless. If true a handler type will be treated as stateful an a new handler instance will be created for each new IBean instance.

Method Detail

supportedInterface

public Class<?> supportedInterface()

Provides the interface that is covered by the corresponding handler.

Returns:

the extension interface type

handlerType

public Class<? extends ExtensionHandler> handlerType()

Provides the ExtensionHandler implementation responsible for the supported interface.

Returns:

the ExtensionHandler implementation

handlerStateful

public boolean handlerStateful()

Returns true if the handler is stateful and needs to have an individual instance per IBean object.

Returns:

false if a single handler instance can handle all bean objects

supportedInterfaceAndSuperInterfaces

public List<Class<?>> supportedInterfaceAndSuperInterfaces()

Returns the supportedInterface() together with all sub-interfaces of that interface.

Returns:

a list of interface types. Never null but might be empty.
