      key - the value for the key record component

  • Method Details

    • compareTo

      public int compareTo(CharArray o)
      Specified by:
      compareTo in interface Comparable<CharArray>

    • getKey

      public char[] getKey()

    • equals

      public boolean equals(Object obj)
      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. All components in this record class are compared with Objects::equals(Object,Object).
      Specified by:
      equals in class Record
      Parameters:
      obj - the object with which to compare
      Returns:
      true if this object is the same as the obj argument; false otherwise.

    • hashCode

      public 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

    • 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

    • key

      public char[] key()
      Returns the value of the key record component.
      Returns:
      the value of the key record component
