Parameters:

value - the Enum to wrap.

Method Detail

getValue

public Enum<?> getValue()

This method returns the raw value of this datatype. This will typically be a standard datatype (like String, Character, Boolean, any type of Number, any type of java.time.LocalDate, etc.).

Specified by:

getValue in interface AttributeReadValue<Enum<?>>

Specified by:

getValue in interface SimpleDatatype<Enum<?>>

Returns:

the value of this datatype.

toString

public String toString()

Returns the official String representation of this Datatype. While the general contract of Object.toString() is very weak and mainly used for debugging, the contract here is very strong. The returned String has to be suitable for end-users and official output to any kind of sink.
ATTENTION:
This method is not supposed to do internationalization (I18N). See NlsMessage for this purpose and implement NlsObject if you want to support I18N/L10N.

Specified by:

toString in interface Datatype

Overrides:

toString in class Object

Returns:

the official String representation to display the value of this Datatype.
