Interface NodeFactory<T>

Type Parameters:

T -

public interface NodeFactory<T>

A factory for creating instances. The SEP will call this method to create nodes. Instance re-use. To ensure that node instances are re-used there are two approaches: 1. The factory caches the node, and returns the same instance for the same configuration. 2. The factory creates new nodes, but the node overrides hashcode and equals so interchangeable node instances will return true when equality is tested. The framework will only use one of the instances and ignore the subsequently created instances. Fluxtion employs the ServiceLoader pattern to register NodeFactories. Please read the java documentation describing the meta-data a factory implementor must provide to register a factory using the ServiceLoader pattern.
