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

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.

The library and compiler parsers had the interesting distinction of different behavior for nextch (a function for which there are a total of two plausible behaviors, so we know the design space was fully explored.) One of them returned the value of nextch before the increment and one of them the new value.

One of them returned the value of nextch before the increment and one of them the new value. So to unify code we have to at least temporarily abstract over the nextchs.

Tests whether the argument (that

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:
x
and y
of type AnyRef
, multiple invocations of
x.eq(y)
consistently returns true
or consistently returns false
.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
).

well as the interaction between finalize

and exceptions, are all platform dependent.
