Method Summary

All Methods Static Methods Concrete Methods
Modifier and Type	Method	Description
`static <E> Function<E,E>`	`asFunction(Interner<E> interner)`	Returns a function that delegates to the `Interner.intern(E)` method of the given interner.
`static Interners.InternerBuilder`	`newBuilder()`	Returns a fresh `Interners.InternerBuilder` instance.
`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.

  - newBuilder
```
public static Interners.InternerBuilder newBuilder()
```
    Returns a fresh Interners.InternerBuilder instance.
  - 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
```
@GwtIncompatible("java.lang.ref.WeakReference")
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.
  - asFunction
```
public static <E> Function<E,E> asFunction(Interner<E> interner)
```
    Returns a function that delegates to the Interner.intern(E) method of the given interner.
