Method Summary

Modifier and Type	Method and Description
static boolean	assignableType(Class<?> left, Class<?> right) It is OK to assign an expression typed right to a variable typed left.
static Constructor<?>	findConstructor(Class<?> targetClass, Class<?>[] formalArguments) Similar to findMethod(), but for constructors rather than regular methods
static Method	findMethod(Class<?> targetClass, String name, Class<?>[] formalArguments) An utility building on the functionality of getMethod(), to provide the javaMessage predicate with method argument polymorphism.
static String	shortClassName(Class<?> c) Returns just the name of the class, with no package information.

Method Detail

findMethod

public static Method findMethod(Class<?> targetClass,
                                String name,
                                Class<?>[] formalArguments)
                         throws NoSuchMethodException

An utility building on the functionality of getMethod(), to provide the javaMessage predicate with method argument polymorphism. If the type signatures do not match exactly, searches all method signatures to see if their arguments are type-compatible.

Throws:

NoSuchMethodException

findConstructor

public static Constructor<?> findConstructor(Class<?> targetClass,
                                             Class<?>[] formalArguments)
                                      throws NoSuchMethodException

Similar to findMethod(), but for constructors rather than regular methods

Throws:

NoSuchMethodException

assignableType

public static boolean assignableType(Class<?> left,
                                     Class<?> right)

It is OK to assign an expression typed right to a variable typed left. Delegates on isAssignableFrom

shortClassName

public static String shortClassName(Class<?> c)

Returns just the name of the class, with no package information. That is, if foo.bar.Mumble were the class passed in, the string "Mumble" would be returned. Similarly, if the class that is passed in is a.b.Class$InnerClass the string returned would be InnerClass.
