### Question:
FlowEncapsulationTypeConverter implements AttributeConverter<FlowEncapsulationType, String> { @Override public FlowEncapsulationType toEntityAttribute(String value) { if (value == null || value.trim().isEmpty()) { return null; } return FlowEncapsulationType.valueOf(value); }  @Override String toGraphProperty(FlowEncapsulationType value); @Override FlowEncapsulationType toEntityAttribute(String value); static final FlowEncapsulationTypeConverter INSTANCE; }### Answer:
@Test public void shouldConvertToEntity() { assertEquals(FlowEncapsulationType.TRANSIT_VLAN, FlowEncapsulationTypeConverter.INSTANCE.toEntityAttribute("TRANSIT_VLAN")); }
