Class Pool<T extends de.tsl2.nano.execution.IPRunnable<?,?>>

java.lang.Object

de.tsl2.nano.incubation.specification.Pool<T>

Direct Known Subclasses:

ActionPool, RulePool

public class Pool<T extends de.tsl2.nano.execution.IPRunnable<?,?>>
extends Object

Generic Pool holding all defined (loaded) instances of an IPRunnable implementation. Useful for e.g. Rules, Queries and Actions.

should be used as singelton by a service-factory. persists its runnables in a directory, given by getDirectory() (using the pool instance generic type as directory name).

It is possible to hold different extensions of the given generic type. Then you access them through ghe getter get(String, Class) - otherwise it is sufficient to call get(String) using internally the default type, evaluated by getType().
