    • equals

      public boolean equals(Object o)
      Description copied from interface: TDoubleCollection
      Compares the specified object with this collection for equality. Returns true if the specified object is also a collection, the two collection have the same size, and every member of the specified collection is contained in this collection (or equivalently, every member of this collection is contained in the specified collection). This definition ensures that the equals method works properly across different implementations of the collection interface.

      Overrides:
      equals in class Object

    • hashCode

This ensures that s1.equals(s2) implies that s1.hashCode()==s2.hashCode() for any two collection s1 and s2, as required by the general contract of Object.hashCode().
      Specified by:
      hashCode in interface TDoubleCollection
