    • canVerify

      public boolean canVerify()
      Returns whether the signature can be verified.

      Verifiable signature is not the same as verified signature. A signatures is verifiable if it has proper sender UUID and signature data. However, it can still fail to verify.

      Returns:
      whether the signature can be verified

      public boolean canVerifyFrom(UUID expectedSender)
      Returns whether the message is from expectedSender and the signature can be verified.

      Verifiable signature is not the same as verified signature. A signatures is verifiable if it has proper sender UUID and signature data. However, it can still fail to verify.

      Returns:

    • toString

      public final 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

    • equals

      public final boolean equals(Object object)
      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:
      object - the object with which to compare
      Returns:
      true if this object is the same as the object argument; false otherwise.
