5. def classSignature(cls: Class[_]): String

   

   Generate a runtime signature for a class (type).

   Generate a runtime signature for a class (type). For instance:

   java.lang.String  ->  Ljava/lang/String;
   int               ->  I

   cls

13. def isOfType[T](v: Any)(implicit arg0: ClassTag[T]): Boolean

    

    Determine if a value is of, or is assignable to, a specified type.

    Determine if a value is of, or is assignable to, a specified type. Works with generics. Example of use:

    val value: Any = ...
    assert(isOfType[Map[String,Int]](value))

    T

    the type against which to check the value

    returns

    whether or not value conforms to type T

14. def isPrimitive[T](cls: Class[T])(implicit arg0: ClassTag[T]): Boolean

    

    Determine whether a class represents an underlying primitive or not.

    Determine whether a class represents an underlying primitive or not. For instance, Int, Float and Unit all represent underlying primitives. Note that Java classes are considered primitives if they *are*, in fact, primitives, or if they represent boxed forms of primitives.

    cls

    the class

    returns

    true if the class represents a primitive, false if not

15. def isPrimitive(obj: Any): Boolean

    

    Determine whether an object is a primitive or not.

    Determine whether an object is a primitive or not.

    obj

    the object

    returns

    true if its class is a primitive, false if not.

16. def loadClass(classLoader: ClassLoader, className: String, classBytes: Array[Byte]): Class[_]

    

    Convenience method to load a class from an array of class bytes.

    Convenience method to load a class from an array of class bytes.

    classLoader

    the class loader to use

    className

    the name of the class

    classBytes

    the class's byte code

    returns

    the loaded class

17. def methodSignature(method: Method): String

    

    Generate a runtime signature for a method.

    Generate a runtime signature for a method. See, for instance: http://journals.ecs.soton.ac.uk/java/tutorial/native1.1/implementing/method.html

    method

    method, from java.lang.reflect

    returns

    its string signature

18. def methodSignature(returnType: Class[_], paramTypes: Array[Class[_]]): String
