Class StringPool

java.lang.Object

org.openl.util.StringPool

public final class StringPool
extends Object

A cache pool for strings. This util is a replacement for Java's String.intern() but it does not use Perm Gen. All strings in this pool are weak referenced, so they can be garbage collected.

Note that this implementation is synchronized.
