A reflective mirror for the given object.
A reflective mirror for the given object.
Such a mirror can be used to further reflect against the members of the object to get/set fields, invoke methods and inspect inner classes and objects.
Reflects against a static class symbol and returns a mirror that can be used to create instances of the class, inspect its companion object or perform further reflections.
Reflects against a static class symbol and returns a mirror that can be used to create instances of the class, inspect its companion object or perform further reflections.
To get a class symbol by the name of the class you would like to reflect,
use <this mirror>.classSymbol(<runtime class loaded by its name>)
.
The input symbol can be either private or non-private (Scala reflection transparently deals with visibility). It must be static, i.e. either top-level or nested within one or several static objects.

If the name points to a type alias, it's recursively dealiased and its target is returned. If you need a symbol that corresponds to the type alias itself, load it directly from the package class:
scala> cm.staticClass("scala.List") res0: reflect.runtime.universe.ClassSymbol = class List
scala> res0.fullName res1: String = scala.collection.immutable.List
scala> cm.staticPackage("scala") res2: reflect.runtime.universe.ModuleSymbol = package scala
scala> res2.moduleClass.typeSignature member newTypeName("List") res3: reflect.runtime.universe.Symbol = type List
scala> res3.fullName res4: String = scala.List
To be consistent with Scala name resolution rules, in case of ambiguity between a package and an object, the object is never been considered.
For example for the following code:
package foo { class B }
object foo { class A class B }
staticClass("foo.B") will resolve to the symbol corresponding to the class B declared in the package foo, and staticClass("foo.A") will throw a MissingRequirementException (which is exactly what scalac would do if this fully qualified class name is written inside any package in a Scala program).
In the example above, to load a symbol that corresponds to the class B declared in the object foo, use staticModule("foo") to load the module symbol and then navigate typeSignature.members of its moduleClass.

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

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 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
).

A refinement of scala.reflect.api.Mirror for runtime reflection using JVM classloaders.
With this upgrade, mirrors become capable of converting Scala reflection artifacts (symbols and types) into Java reflection artifacts (classes) and vice versa. Consequently, refined mirrors become capable of performing reflective invocations (getting/setting field values, calling methods, etc).
