2. final def !=(arg0: Any): Boolean

   Test two objects for inequality.

   Test two objects for inequality.

   returns

   true if !(this == that), false otherwise.

   Definition Classes

   Any

3. final def ##(): Int

   Equivalent to x.hashCode except for boxed numeric types.

   Equivalent to x.hashCode except for boxed numeric types. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them.

   returns

   a hash value consistent with ==

   AnyRef

5. final def ==(arg0: Any): Boolean

   Test two objects for equality.

   Test two objects for equality.

   returns

   true if the receiver object is equivalent to the argument; false otherwise.

   Definition Classes

   Any

6. final def asInstanceOf[T0]: T0

   Cast the receiver object to be of type T0.

   Cast the receiver object to be of type T0.

   Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

   returns

   the receiver object.

   Definition Classes

   Any

   Exceptions thrown

   ClassCastException

   if the receiver object is not an instance of the erasure of type T0.

7. def clone(): AnyRef

   Create a copy of the receiver object.

   Create a copy of the receiver object.

   The default implementation of the clone method is platform dependent.

   returns

   a copy of the receiver object.

8. final def eq(arg0: AnyRef): Boolean

   Tests whether the argument (arg0) is a reference to the receiver object (this).

   Tests whether the argument (arg0) is a reference to the receiver object (this).

   The eq method implements an equivalence relation on non-null instances of AnyRef, and has three additional properties:

   • It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
   • For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
   • null.eq(null) returns true.

   When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

   returns

   true if the argument is a reference to the receiver object; false otherwise.

   AnyRef

9. def equals(arg0: Any): Boolean

   The equality method for reference types.

   The equality method for reference types. See equals in Any.

   returns

   true if the receiver object is equivalent to the argument; false otherwise.

10. def finalize(): Unit

    Called by the garbage collector on the receiver object when there are no more references to the object.

    Called by the garbage collector on the receiver object when there are no more references to the object.

    The details of when and if the finalize method is invoked, as well as the interaction between finalize and non-local returns and exceptions, are all platform dependent.
