    The symbol corresponding to the globally accessible class with the given fully qualified name fullName.

    The symbol corresponding to the globally accessible class with the given fully qualified name fullName.

    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: scala.reflect.runtime.universe.ClassSymbol = class List

    scala> res0.fullName res1: String = scala.collection.immutable.List

    scala> cm.staticPackage("scala") res2: scala.reflect.runtime.universe.ModuleSymbol = package scala

    scala> res2.moduleClass.info member TypeName("List") res3: scala.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 ScalaReflectionException.

    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 info.members of its moduleClass.

    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.

    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.

    returns

    a hash value consistent with ==

    Permalink

    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.

    Permalink

    Tests whether the argument (that) is a reference to the receiver object (this).

    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:

    • It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
    • For any non-null instance 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).

    returns

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