def hashCode(): Int

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.

B
the type of the second half of the returned pairs
That
the class of the returned collection. Where possible, That is the same class as the current collection class Repr, but this depends on the element type (A1, B) being admissible for that class, which means that an implicit instance of type CanBuildFrom[Repr, (A1, B), That]. is found.
