/**
 * A multiset which maintains the ordering of its elements, according to either their natural order

 * Comparable#compareTo} or {@link Comparator#compare} instead of {@link Object#equals} to determine

#### Index Settings Migration

Fess uses OpenSearch/Elasticsearch internally, so you can:

1. Export index mappings and settings from source
2. Apply custom analyzers in Fess's `fess_config.properties`
3. Create synonym dictionaries in Fess's dictionary directory

  public ImmutableMultiset<K> keys() {
    return (ImmutableMultiset<K>) super.keys();
  }

  @Override
  ImmutableMultiset<K> createKeys() {
    return new Keys();
  }

  @SuppressWarnings("serial") // Uses writeReplace, not default serialization
  @WeakOuter
  private final class Keys extends ImmutableMultiset<K> {
    @Override
    public boolean contains(@Nullable Object object) {
      return containsKey(object);

   *
   * {@snippet :
   * CharMatcher.is('a').replaceFrom("radar", 'o')
   * }
   *
   * ... returns {@code "rodor"}.
   *
   * <p>The default implementation uses {@link #indexIn(CharSequence)} to find the first matching
   * character, then iterates the remainder of the sequence calling {@link #matches(char)} for each
   * character.

<summary>Or use <code>async def</code>...</summary>

If your code uses `async` / `await`, use `async def`:

```Python hl_lines="7  12"
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
async def read_root():
    return {"Hello": "World"}

          && hashCodeInsensitiveToArgReference(
              factory, args, i, generateDummyArg(param, newFreshValueGenerator()))) {
        // If the implementation uses identityHashCode(), referential equality is
        // probably intended. So no point in using an equal-but-different factory argument.
        // We check twice to avoid confusion caused by accidental hash collision.
