Cast the receiver object to be of type T0.

Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at

Class loader that is a mastermind behind the reflexive mirror.
Class loader that is a mastermind behind the reflexive mirror.
By default it is set to system classloader (more precisely, to the classloader that loads the scala.reflect.package class).
However, sometimes it is useful to have a mirror services by a custom classloader.
There are two ways to customize the classLoader:
1) Create a new mirror using the scala.reflect.mkMirror(classLoader: ClassLoader) method
2) Set classLoader to the new value
The first, immutable, way should be strongly preferred in most situation.
However sometimes it is necessary to migrate the default reflexive mirror (scala.reflect.mirror) to a new classloader.
In that and only that case, use the setter, but be very careful not to introduce inconsistencies.

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).
true if the argument is a reference to the receiver object; false otherwise.

A creator for existential types.
A creator for existential types. This generates:
tpe1 where { tparams }
where tpe1 is the result of extrapolating tpe wrt 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 wrt 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.

Given an expression, generate a tree that when compiled and executed produces the original tree.
Given an expression, generate a tree that when compiled and executed produces the original tree. The produced tree will be bound to the Universe it was called from.
For instance, given the abstract syntax tree representation of the <[ x + 1 ]> expression:
Apply(Select(Ident("x"), "+"), List(Literal(Constant(1))))
The reifier transforms it to the following expression:
<[ val $mr: scala.reflect.api.Universe = <reference to the Universe that calls the reify> $mr.Expr[Int]($mr.Apply($mr.Select($mr.Ident($mr.newFreeVar("x", <Int>, x), "+"), List($mr.Literal($mr.Constant(1)))))) ]>
Reification performs expression splicing (when processing Expr.eval and Expr.value) and type splicing (for every type T that has a TypeTag[T] implicit in scope):
val two = mirror.reify(2) // Literal(Constant(2)) val four = mirror.reify(two.eval + two.eval) // Apply(Select(two.tree, newTermName("$plus")), List(two.tree))
def macroImpl[T](c: Context) = { ... // T here is just a type parameter, so the tree produced by reify won't be of much use in a macro expansion // however, if T were annotated with c.TypeTag (which would declare an implicit parameter for macroImpl) // then reification would subtitute T with the TypeTree that was used in a TypeApply of this particular macro invocation val factory = c.reify{ new Queryable[T] } ... }
The transformation looks mostly straightforward, but it has its tricky parts: * Reifier retains symbols and types defined outside the reified tree, however locally defined entities get erased and replaced with their original trees * Free variables are detected and wrapped in symbols of the type FreeVar * Mutable variables that are accessed from a local function are wrapped in refs * Since reified trees can be compiled outside of the scope they've been created in, special measures are taken to ensure that all members accessed in the reifee remain visible
