### Question:
TypeManager implements Mutable { ObjList<TypeAdapter> getAllAdapters() { return probes; } TypeManager(
            TextConfiguration configuration,
            DirectCharSink utf8Sink
    ); @Override void clear(); InputFormatConfiguration getInputFormatConfiguration(); TypeAdapter getProbe(int index); int getProbeCount(); TypeAdapter getTypeAdapter(int columnType); DateUtf8Adapter nextDateAdapter(); TypeAdapter nextTimestampAdapter(boolean decodeUtf8, TimestampFormat format, TimestampLocale locale);  }### Answer:
@Test public void testEmpty() throws JsonException { TypeManager typeManager = createTypeManager("/textloader/types/empty.json"); Assert.assertEquals("[CHAR,INT,LONG,DOUBLE,BOOLEAN,LONG256]", typeManager.getAllAdapters().toString()); }
