  - temporalAccessorValue
```
public java.time.temporal.TemporalAccessor temporalAccessorValue()
                                                          throws java.time.DateTimeException
```
    Description copied from interface: Literal
    Retrieves the temporal accessor value of this literal.
    A temporal accessor representation can be given for literals whose label conforms to the syntax of the following XML Schema 1.1 date/time datatypes:
    - xsd:dateTime,
    - xsd:time,
    - xsd:date,
    - xsd:gYearMonth,
    - xsd:gYear,
    - xsd:gMonthDay,
    - xsd:gDay,
    - xsd:gMonth.
    Temporal accessor representations may be converted to specific java.time values like OffsetDateTime using target static factory methods, for instance OffsetDateTime.from(literal.temporalAccessorValue()).
    
    Note however that java.time doesn't include dedicated classes for some legal XML Schema date/time values, like offset dates (for instance, 2020-11-16+01:00) and xsd:gDay (for instance, ---16).
    Specified by:
    
    temporalAccessorValue in interface Literal
    
    Returns:
    
    the temporal accessor value of this literal
    
    Throws:
    
    java.time.DateTimeException - if this literal cannot be represented by a TemporalAccessor value

  - temporalAmountValue
```
public java.time.temporal.TemporalAmount temporalAmountValue()
                                                      throws java.time.DateTimeException
```
    Description copied from interface: Literal
    
    Retrieves the temporal amount value of this literal.
    A temporal amount representation can be given for literals whose label conforms to the syntax of the XML Schema 2 xsd:duration datatype.
    
    The adoption of the XML Schema 2 definition is a known deviation from the RDF 1.1 standard; well-formedness rules are relaxed to consider all duration components as optional and freely mixable.
    
    Temporal amount representations may be converted to specific java.time values like Duration using target static factory methods, for instance Duration.from(literal.temporalAmountValue()).
    
    Note however that java.time doesn't include dedicated classes for legal XML Schema duration values including both date and time components (for instance, P1YT23H).
    
    Specified by:
    
    temporalAmountValue in interface Literal
    
    Returns:
    
    the temporal amount value of this literal
    
    Throws:
    
    java.time.DateTimeException - if this literal cannot be represented by a TemporalAmount value

  - calendarValue
```
public XMLGregorianCalendar calendarValue()
```
    Description copied from interface: Literal
    
    Returns the XMLGregorianCalendar value of this literal. A calendar representation can be given for literals whose label conforms to the syntax of the following XML Schema datatypes: dateTime, time, date, gYearMonth, gMonthDay, gYear, gMonth or gDay.
    
    Specified by:
    
    calendarValue in interface Literal
    
    Returns:
    
    The calendar value of the literal.
  - equals
```
public boolean equals(Object o)
```
    Description copied from interface: Literal
    
    Compares this literal to another object.
    
    Specified by:
    
    equals in interface Literal
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    o - the object to compare this literal to
    
    Returns:
    
    true, if the other object is an instance of Literal and if their labels, language tags and datatypes are equal
  - hashCode
```
public int hashCode()
```
    Description copied from interface: Literal
    
    Computes the hash code of this literal.
    
    Specified by:
    
    hashCode in interface Literal
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    a hash code for this literal computed as Literal.getLabel().hashCode()
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
