|
static <E> Interner |

|
static <E> Interner |

public static <E> Interner<E> newStrongInterner()
newWeakInterner()
. Note that unlike
String.intern()
, using this interner does not consume memory in the permanent generation.
@GwtIncompatible(value="java.lang.ref.WeakReference") public static <E> Interner<E> newWeakInterner()
newStrongInterner()
, but is the best alternative when the memory usage of that implementation is unacceptable. Note that unlike
String.intern()
, using this interner does not consume memory in the permanent generation.
public static <E> Function<E ,E> asFunction(Interner <E> interner)
Interner.intern(E)
method of the given interner.
