Class StoredListFactory

java.lang.Object

com.j_spaces.kernel.StoredListFactory

public final class StoredListFactory
extends Object

StoredListFactory returns a IStoredList implementation, according to the Java version the sources were compiled. This is due to performance profiling conducted on both JDK1.4 and JDK1.5 - Thus, using 1.4 will return IStoredList, and using 1.5 will return SimpleLockStoredList.

Since:

4.1

Version:

1.0
