### Question:
CharSequenceMap implements SequenceMap<CharSequence> { public long get(final CharSequence value) { return search(value, searchEntryHandler); } CharSequenceMap(final int maxKeyLength, final int initialSize, final long missingValue);  CharSequenceMap(
        final int maxKeyLength, final int initialSize,
        final long missingValue, final IntFunction<ByteBuffer> bufferFactory);   CharSequenceMap(
        final int maxKeyLength, final int initialSize,
        final ToIntFunction<CharSequence> hash, final long missingValue,
        final IntFunction<ByteBuffer> bufferFactory); void put(final CharSequence value, final long id); long get(final CharSequence value); long remove(final CharSequence value); int size(); void rehash();  }### Answer:
@Test void shouldNotRetrieveUnknownValue() { assertThat(map.get(SEARCH_TERM)).isEqualTo(MISSING_VALUE); }
