Method Detail

getMethod

static java.lang.reflect.Method getMethod(java.lang.Class klass,
                                          java.lang.String name,
                                          java.lang.Object[] arguments)
                                   throws java.lang.NoSuchMethodException

Searches a Method which can accept the given arguments.

getConstructor

static java.lang.reflect.Constructor getConstructor(java.lang.Class klass,
                                                    java.lang.Object[] arguments)
                                             throws java.lang.NoSuchMethodException

---

getArgumentTypes

private static java.lang.Class[] getArgumentTypes(java.lang.Object[] arguments)

Transforms an array of argument objects into an array of argument types. For each argument being null the argument is null, too. An argument type being null means: Accepts everything (although this can be ambigous).

---

matchingArgumentTypes

private static boolean matchingArgumentTypes(java.lang.Class[] methodArgTypes,
                                             java.lang.Class[] suppliedArgTypes)

Tests whether the argument types supplied to the method argument types are assignable. In addition to the assignment specifications this method handles the primitive's wrapper classes as if they were of their primitive type (e.g Boolean.class equals Boolean.TYPE). When a supplied argument type is null it is assumed that no argument object was supplied for it and the test for this particular parameter will pass.
