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

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
).

EXPERIMENTAL
A refinement of scala.reflect.api.Universe for runtime reflection using JVM classloaders.
The refinement consists of an upgrade to the mirror API, which gets extended from scala.reflect.api.Mirror to scala.reflect.api.JavaMirrors#JavaMirror.
See the Reflection Guide for details on how to use runtime reflection.
