  - ### Method Detail

    - #### 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`

    - #### equals

          public boolean equals(Object o)

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

    - #### hashCode

          public int hashCode()

      Description copied from interface: `BNode`
      Computes the hash code of this blank node.
      Specified by:
        `hashCode` in interface `BNode`
      Overrides:
        `hashCode` in class `Object`
      Returns:
        a hash code for this blank node computed as `BNode.getID()``.hashCode()`

    - #### toString

          public String toString()

      Overrides:
        `toString` in class `Object`
