Interface TunableHandler

public interface TunableHandler

Interface for classes that deal with reading out and writing back Tunables and their properties. TunableHandler classes are provided to the system via TunableHandlerFactory services. Different presentation mediums (e.g. Swing GUI, command line, etc.) will demand different TunableHandler and TunableHandlerFactory implementations to display, parse, get, and set the necessary Tunable values. Each different type of object (String, Double, ListSingleSelection will need its own TunableHandler/TunableHandlerFactory pair to process fields/methods of that type.

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

boolean	controlsMutuallyExclusiveNestedChildren() Returns true if the associated Tunable allows switching of mutually exclusive nested children, else false.
String	dependsOn() Returns the dependsOn property of the associated Tunable.
String	getChildKey() Returns the name of the key that determines the selection of which controlled nested child is currently presented, or the empty string if controlsMutuallyExclusiveNestedChildren() returns false.
String	getDescription() Returns the associated Tunable's description.
String[]	getGroups() Returns the associated Tunable's groups or nesting hierarchy.
String	getName() Returns a name representing a tunable property.
Properties	getParams() Returns the parsed result from Tunable.getParams().
String	getQualifiedName() Returns the name of the underlying class of the tunable followed by a dot and the name of the tunable field or getter/setter root name.
Class<?>	getType() Returns the class type of the field or method annotated by Tunable.
Object	getValue() Returns an object describing a field / get method annotated with Tunable or null if no field / get method has been associated with this handler.
void	handle() Updates an annotated object with the current value as retrieved from the the user interface generated by this handler.
String[]	listenForChange() Returns the listenForChange property of the associated Tunable.
void	setValue(Object newValue) Attempts to set the value of the associated field or set method that has been annotated with Tunable.
