### Question:
Metadata { @Nullable public <T> T get(Key<T> key) { for (int i = size - 1; i >= 0; i--) { if (bytesEqual(key.asciiName(), name(i))) { return key.parseBytes(value(i)); } } return null; } Metadata(byte[]... binaryValues);   Metadata(int usedNames, byte[]... binaryValues);  Metadata(); boolean containsKey(Key<?> key); @Nullable T get(Key<T> key); @Nullable Iterable<T> getAll(final Key<T> key); @SuppressWarnings("deprecation") // The String ctor is deprecated, but fast. Set<String> keys(); void put(Key<T> key, T value); boolean remove(Key<T> key, T value); Iterable<T> removeAll(Key<T> key); @ExperimentalApi("https://github.com/grpc/grpc-java/issues/4691") void discardAll(Key<T> key); void merge(Metadata other); void merge(Metadata other, Set<Key<?>> keys); @SuppressWarnings("BetaApi") // BaseEncoding is stable in Guava 20.0 @Override String toString(); static final String BINARY_HEADER_SUFFIX; static final BinaryMarshaller<byte[]> BINARY_BYTE_MARSHALLER; static final AsciiMarshaller<String> ASCII_STRING_MARSHALLER; }### Answer:
@Test public void testWriteRaw() { Metadata raw = new Metadata(KEY.asciiName(), LANCE_BYTES); Fish lance = raw.get(KEY); assertEquals(lance, new Fish(LANCE)); assertEquals(lance, raw.get(KEY)); }
