def anyValClass[T <: AnyVal : ClassTag](value: T): Class[T]

Return the class object representing an unboxed value type, e.g., classOf[int], not classOf[java.lang.Integer].

Return the class object representing an unboxed value type, e.g., classOf[int], not classOf[java.lang.Integer]. The compiler rewrites expressions like 5.getClass to come here.

def stringOf(arg: Any): String

Given any Scala value, convert it to a String.

Given any Scala value, convert it to a String.

The primary motivation for this method is to provide a means for correctly obtaining a String representation of a value, while avoiding the pitfalls of naively calling toString on said value. In particular, it addresses the fact that (a) toString cannot be called on null and (b) depending on the apparent type of an array, toString may or may not print it in a human-readable form.

Value parameters:
arg

the value to stringify

Returns:

a string representation of arg.

def toArray[T](xs: Seq[T]): Array[AnyRef]

Convert an array to an object array.

Convert an array to an object array. Needed to deal with vararg arguments of primitive types that are passed to a generic Java vararg parameter T ...
