public AbstractSimpleDatatypeBase()

The constructor.

Method Detail

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

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

Specified by:

toString in class AbstractDatatype

Returns:

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

getValue

public static <V> V getValue(SimpleDatatype<V> datatype)

Type Parameters:

V - is the generic type of the contained value.

Parameters:

datatype - is the SimpleDatatype to get the value from.

Returns:

the value of the given datatype or null if datatype is null.
