A method that should be called from every well-designed equals method that is open to be overridden in a subclass.

The equality method defined in AnyRef
.
Returns a hash code value for the object.
Returns a hash code value for the object.
The default hashing algorithm is platform dependent.
Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)
) yet
not be equal (o1.equals(o2)
returns false
). A degenerate implementation could always return 0
.
However, it is required that if two objects are equal (o1.equals(o2)
returns true
) that they have
identical hash codes (o1.hashCode.equals(o2.hashCode)
). Therefore, when overriding this method, be sure
to verify that the behavior is consistent with the equals
method.
the hash code value for the object.
return k for a product A(x_1,...,x_k)
For a product A(x_1,...,x_k)
, returns x_(n+1)
for 0 <= n < k
use productIterator instead
An iterator that returns all fields of this product
An iterator that returns all fields of this product
By default the empty string.
Set tpe to give tp

Returns a string representation of the object.
Returns a string representation of the object.
