A creator for type applications
A creator for existential types.
A creator for existential types. This generates:
tpe1 where { tparams }
where tpe1
is the result of extrapolating tpe
with regard to tparams
.
Extrapolating means that type variables in tparams
occurring
in covariant positions are replaced by upper bounds, (minus any
SingletonClass markers), type variables in tparams
occurring in
contravariant positions are replaced by upper bounds, provided the
resulting type is legal with regard to stability, and does not contain
any type variable in tparams
.
The abstraction drops all type parameters that are not directly or
indirectly referenced by type tpe1
. If there are no remaining type
parameters, simply returns result type tpe
.

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

Test two objects for equality.

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.

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:
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
).

if the argument is a reference to the receiver object; false
