2. #### final def ##(): Int

   Equivalent to `x.hashCode` except for boxed numeric types and `null`.

   Equivalent to `x.hashCode` except for boxed numeric types and `null`. 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. For `null` returns a hashcode where `null.hashCode` throws a `NullPointerException`.

   returns

     a hash value consistent with ==

    Add forwarders for all methods defined in `module` that don't conflict with methods in the companion class of `module`. A conflict arises when a method with the same name is defined both in a class and its companion object: method signature is not taken into account.

20. #### def addStaticInit(mopt: Option[Global.icodes.IMethod]): Unit

21. #### 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.

    Exceptions thrown

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

45. #### 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.

    Definition Classes
      AnyRef

46. #### def equals(arg0: Any): Boolean

    The equality method for reference types. Default implementation delegates to `eq`.

    See also `equals` in scala.Any.

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

47. #### def finalize(): Unit

    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.

    Returns a ScalaSignature annotation if it must be added to this class, none otherwise. This annotation must be added to the class' annotations list when generating them.

    Depending on whether the returned option is defined, it adds to `jclass` one of: (a) the ScalaSig marker attribute (indicating that a scala-signature-annotation aka pickle is present in this class); or (b) the Scala marker attribute (indicating that a scala-signature-annotation aka pickle is to be found in another file).

    jclassName

      The class file that is being readied.

    sym

      The symbol for which the signature has been entered in the symData map. This is different than the symbol that is being generated in the case of a mirror class.

    returns

      An option that is:

      - defined and contains an AnnotationInfo of the ScalaSignature type, instantiated with the pickle signature for sym.
      - empty if the jclass/sym pair must not contain a pickle.

    Test whether the dynamic type of the receiver object is `T0`.

    Note that the result of the test is modulo Scala's erasure semantics. Therefore the expression `1.isInstanceOf[String]` will return `false`, while the expression `List(1).isInstanceOf[List[String]]` will return `true`. 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 specified type.

    returns

      `true` if the receiver object is an instance of erasure of type `T0`; `false` otherwise.

    Return the name of this symbol that can be used on the Java platform. It removes spaces from names.

    Special handling: scala.Nothing erases to scala.runtime.Nothing$ scala.Null erases to scala.runtime.Null$

    This is needed because they are not real classes, and they mean 'abrupt termination upon evaluation of that expression' or null respectively. This handling is done already in GenICode, but here we need to remove references from method signatures to these types, because such classes cannot exist in the classpath: the type checker will be very confused.
