Package org.coliper.ibean.proxy

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

Method Summary

Modifier and Type	Method	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.
