### Question:
FieldValue implements EncodableData { public long getSize() { return 1 + value.getSize(); } private  FieldValue(Type type, EncodableData value); long getSize(); long getValueSize(); @Override void write(ByteBuf buf); static FieldValue parse(ByteBuf buf); Type getType(); EncodableData getValue(); static FieldValue parseLongInt(int value); static FieldValue parseLongInt(LongInt value); static FieldValue parseLongString(String value); static FieldValue parseLongString(LongString value); static FieldValue parseShortString(String value); static FieldValue parseShortString(ShortString value); static FieldValue parseBoolean(io.ballerina.messaging.broker.common.data.types.Boolean amqpBoolean); static FieldValue parseShortShortInt(byte value); static FieldValue parseShortShortInt(ShortShortInt value); static FieldValue parseLongLongInt(long value); static FieldValue parseLongLongInt(LongLongInt value); static FieldValue parseFieldTable(FieldTable fieldTable); static FieldValue parseShortInt(ShortInt value); static FieldValue parseFloat(Float value); static FieldValue parseDouble(Double value); static FieldValue parseDecimal(Decimal value); static FieldValue parseShortShortUint(ShortShortUint value); static FieldValue parseShortUint(ShortUint value); static FieldValue parseLongUint(LongUint value); @Override boolean equals(Object obj); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void testGetSize() throws Exception { Assert.assertEquals(TEST_OBJECT.getSize(), 1 + 4); }
