Interface TunableHandlerFactory<T extends TunableHandler>

Type Parameters:

T - The specific type of TunableHandler that will be created by this factory.

All Known Subinterfaces:

GUITunableHandlerFactory<T>, StringTunableHandlerFactory<T>, TunablePropertyHandlerFactory<T>

All Known Implementing Classes:

BasicTunableHandlerFactory, SimpleGUITunableHandlerFactory

public interface TunableHandlerFactory<T extends TunableHandler>

A factory service to create a TunableHandler for a single type of object, determined by the type of the field or the return value of the getter method in the appropriate methods. Each type of object (int, float, String) generally needs a different implementation of this interface. Each implementation is expected to be registered as an OSGi service. TunableInterceptors register the TunableHandlerFactory services of the appropriate type.

Module: work-api

To use this in your app, include the following dependency in your POM:

</dependency>

Cytoscape Backwards Compatibility (SPI Interface): We expect that this interface will be implemented. Therefore to maintain backwards compatibility this interface will only be modified for major version updates.

Method Summary

Modifier and Type	Method and Description
T	createTunableHandler(Field field, Object instance, Tunable tunable) This method returns a TunableHandler for a field annotated as a Tunable if this factory can produce an appropriate handler for this type of field.
T	createTunableHandler(Method getter, Method setter, Object instance, Tunable tunable) This method returns a TunableHandler for a method annotated as a Tunable if this factory can produce an appropriate handler for this type of method.

Method Detail

createTunableHandler

T createTunableHandler(Field field,
                       Object instance,
                       Tunable tunable)

This method returns a TunableHandler for a field annotated as a Tunable if this factory can produce an appropriate handler for this type of field. If the factory cannot produce an appropriate handler, it will return null.

Parameters:

field - Field that needs to be handled.

instance - The object on which we want to read/write the Field.

tunable - Tunable that contains all the information concerning the user interface.

Returns:

T The newly constructed TunableHandler or null if this factory can't handle a field of the specified type.

createTunableHandler

T createTunableHandler(Method getter,
                       Method setter,
                       Object instance,
                       Tunable tunable)

This method returns a TunableHandler for a method annotated as a Tunable if this factory can produce an appropriate handler for this type of method. If the factory cannot produce an appropriate handler, it will return null.
Note that method annotations require both a getter and a setter method to get and set a value. Only the getter method needs to be annotated. The getter method must take no arguments and return a value and be named with the prefix "get". The setter method does not need a Tunable annotation, however the method must take a single argument of the same type as the getter method, it must return void, it must be named with the prefix "set", and the rest of the name must match that of the getter method. See Tunable for an example.

Parameters:

getter - A getter method that has been annotated with Tunable.

setter - A setter method that matches the getter method.

instance - The object on which we want to invoke the getter and setter methods.

tunable - The Tunable that contains all the information concerning the user interface from the getter method.

Returns:

T The newly constructed TunableHandler or null if this factory can't handle the specified type.
