- - ### Constructor Detail

    - #### SimpleTriple

          protected SimpleTriple(Resource subject,
                                 IRI predicate,
                                 Value object)

      Creates a new Triple with the supplied subject, predicate and object.

      Note that creating SimpleStatement objects directly via this constructor is not the recommended approach. Instead, use an instance of `ValueFactory` to create new Triple objects.

      Parameters:
        `subject` - The triple's subject, must not be `null`.
        `predicate` - The triple's predicate, must not be `null`.
        `object` - The triple's object, must not be `null`.

  - ### Method Detail

    - #### getSubject

          public Resource getSubject()

      Description copied from interface: `Triple`
      Gets the subject of this triple.
      Specified by:
        `getSubject` in interface `Triple`
      Returns:
        The triple's subject.

    - #### getPredicate

          public IRI getPredicate()

      Description copied from interface: `Triple`
      Gets the predicate of this triple.
      Specified by:
        `getPredicate` in interface `Triple`
      Returns:
        The triple's predicate.

    - #### getObject

          public Value getObject()

      Description copied from interface: `Triple`
      Gets the object of this triple.
      Specified by:
        `getObject` in interface `Triple`
      Returns:
        The triple's object.

    - #### stringValue

          public String stringValue()

      Description copied from interface: `Value`
      Returns the String-value of a `Value` object. This returns either a `Literal`'s label, a `IRI`'s URI or a `BNode`'s ID.
      Specified by:
        `stringValue` in interface `Value`

    - #### toString

          public String toString()

      Overrides:
        `toString` in class `Object`

    - #### equals

          public boolean equals(Object o)

      Description copied from interface: `Triple`
      Compares this triple to another object.
      Specified by:
        `equals` in interface `Triple`
      Overrides:
        `equals` in class `Object`
      Parameters:
        `o` - the object to compare this triple to
      Returns:
        `true` if the `other` object is an instance of `Triple` and if their subjects, predicates and objects are equal; `false` otherwise

    - #### hashCode

          public int hashCode()

      Description copied from interface: `Triple`
      Computes the hash code of this triple.
      Specified by:
        `hashCode` in interface `Triple`
      Overrides:
        `hashCode` in class `Object`
      Returns:
        a hash code for this triple computed as `Objects.hash`( `Triple.getSubject()`, `Triple.getPredicate()`, `Triple.getObject()`)
