Annotation Type Process

@Target(value=METHOD)
@Retention(value=RUNTIME)
public @interface Process

Annotation to be applied to a method in a class that is annotated with the @Tool annotation This annotation identifies the method to be called during execution.

gather() set to true can be used for units that are happy to receive input from multiple nodes and deal with them. In this case, the method must have a single parameter which is either an Array, or a java.util.Collection or a java.util.List. Specifically, subclasses of List should not be used, but only the interface.

If an array is used, then type checking can occur on the component type of the array. If a Collection or List is used, then the unit will be passed raw Objects.

If gather is not used, then input nodes are restricted to the number of method parameters and are mapped in order of the input nodes.

If gather is used, the inputs are aggregated into an array or List and passed to the method.

Parameters that are changed during the execution of the method are updated via the setParameter() method.
