Constructor Detail

### AbstractDatatype

    public AbstractDatatype()

Method Detail

### getValueType

    protected Class<V> getValueType()

### getBuiltin

    public Datatype.Builtin getBuiltin()

  Specified by:
    `getBuiltin` in interface `Datatype<V>`
  Returns:
    The built-in UPnP standardized type this datatype is mapped to or `null` if this is a custom datatype.

### setBuiltin

    public void setBuiltin(Datatype.Builtin builtin)

### getString

    public String getString(V value)
                     throws InvalidValueException

  Description copied from interface: `Datatype`
  Transforms a value supported by this datatype into a string representation.

  This method calls `Datatype.isValid(Object)` before converting the value, it throws an exception if validation fails.

  Specified by:
    `getString` in interface `Datatype<V>`
  Parameters:
    `value` - The value to transform.
  Returns:
    The transformed value as a string, or an empty string when the value is null, never returns `null`.
  Throws:
    `InvalidValueException`

### isValid

    public boolean isValid(V value)

  Specified by:
    `isValid` in interface `Datatype<V>`
  Parameters:
    `value` - The value to validate or `null`.
  Returns:
    Returns `true` if the value was `null`, validation result otherwise.

### toString

    public String toString()

  Overrides:
    `toString` in class `Object`

### getDisplayString

    public String getDisplayString()

  Specified by:
    `getDisplayString` in interface `Datatype<V>`
  Returns:
    Metadata about this datatype, a nice string for display that describes this datatype (e.g. concrete class name).
