    This phase performs the following functions, each of which could be split out in a mini-phase:

    This phase performs the following functions, each of which could be split out in a mini-phase:

    (1) Adds super accessors for all super calls that either appear in a trait or have as a target a member of some outer class.

    (2) Converts references to parameter fields that have the same name as a corresponding public parameter field in a superclass to a reference to the superclass field (corresponding = super class field is initialized with subclass field). This info is pre-computed by the alias field in Typer. dotc follows a different route; it computes everything in SuperAccessors and changes the subclass field to a forwarder instead of manipulating references. This is more modular.

    (3) Adds protected accessors if the access to the protected member happens in a class which is not a subclass of the member's owner.

    (4) Mangles the names of class-members which are private up to an enclosing non-package class, in order to avoid overriding conflicts. This is a dubious, and it would be better to deprecate class-qualified privates.

    (5) This phase also sets SPECIALIZED flag on type parameters with @specialized annotation. We put this logic here because the flag must be set before pickling.

    It also checks that:

    (1) Symbols accessed from super are not abstract, or are overridden by an abstract override.

    (2) If a symbol accessed accessed from super is defined in a real class (not a trait), there are no abstract members which override this member in Java's rules (see SI-4989; such an access would lead to illegal bytecode)

    (3) Super calls do not go to some synthetic members of Any (see isDisallowed)

    (4) Super calls do not go to synthetic field accessors

    (5) A class and its companion object do not both define a class or module with the same name.

    TODO: Rename phase to "Accessors" because it handles more than just super accessors

  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 ==

  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.

    Exceptions thrown

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

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

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

    Tests whether the argument (that) 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.

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.
