    • PatternKey

      public PatternKey(IRI predicate, int boundMask)
      Creates an instance of a PatternKey record class.
      Parameters:
      predicate - the value for the predicate record component
      boundMask - the value for the boundMask record component

  • Method Details

    • equals

      public boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with the compare method from their corresponding wrapper classes.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • toString

      public String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • predicate

      public IRI predicate()
      Returns the value of the predicate record component.
      Returns:
      the value of the predicate record component

    • boundMask

      public int boundMask()
      Returns the value of the boundMask record component.
      Returns:
      the value of the boundMask record component
