Method Summary

static <E> Interner<E>	newStrongInterner() Returns a new thread-safe interner which retains a strong reference to each instance it has interned, thus preventing these instances from being garbage-collected.
static <E> Interner<E>	newWeakInterner() Returns a new thread-safe interner which retains a weak reference to each instance it has interned, and so does not prevent these instances from being garbage-collected.

Method Detail

newStrongInterner

public static <E> Interner<E> newStrongInterner()

Returns a new thread-safe interner which retains a strong reference to each instance it has interned, thus preventing these instances from being garbage-collected. If this retention is acceptable, this implementation may perform better than newWeakInterner().

newWeakInterner

public static <E> Interner<E> newWeakInterner()

Returns a new thread-safe interner which retains a weak reference to each instance it has interned, and so does not prevent these instances from being garbage-collected. This most likely does not perform as well as newStrongInterner(), but is the best alternative when the memory usage of that implementation is unacceptable.
