Method Detail

invoke

public static Object invoke(Object object,
                            String methodName)

Invokes the method with the specified name on the specified object and throws a NestedApplicationException, if the invocation fails. The method must be public and must not have any parameters.

Parameters:

object - the object the method is invoked from

methodName - the name of the method

Returns:

the result of the method invocation

invoke

public static Object invoke(Object object,
                            String methodName,
                            Object parameter)

Invokes the method with the specified name on the specified object and throws a NestedApplicationException, if the invocation fails. The method must be public and must have exactly one parameter of the type specified by the given parameter.

Parameters:

object - the object the method is invoked from

methodName - the name of the method

parameter - the parameter, must not be null

Returns:

the result of the method invocation

areMethodsEqual

public static boolean areMethodsEqual(Method method1,
                                      Method method2)

Returns if the two specified methods are equal as defined by Method.equals() except that the methods can be defined by different classes.

Parameters:

method1 - the first method to compare

method2 - the second method to compare

Returns:

true if the methods are equal, false otherwise

Throws:

NullPointerException - if one of the methods is null

overrides

public static boolean overrides(Method method1,
                                Method method2)

Returns if method2 overrides method1.

Parameters:

method1 - method to be overridden

method2 - overriding method

Returns:

true if method2 overrides method1, false otherwise

Throws:

NullPointerException - if one of the methods is null

getOverriddenMethods

public static Set<Method> getOverriddenMethods(Class<?> clazz,
                                               Method[] methods)

Returns all methods in methods that are overridden in the specified class hierarchy. The returned Set contains all overridden methods and all overriding methods.

Parameters:

clazz - the class hierarchy

methods - the Set of methods

Returns:

all overridden and overriding methods.

getMatchingDeclaredMethods

public static Method[] getMatchingDeclaredMethods(Class<?> theClass,
                                                  String expr)

Returns the declared methods of the specified class whose names are matching the specified regular expression.

Parameters:

theClass - the class whose methods are examined

expr - the regular expression

Returns:

the matching methods

getMethodsSortedByInheritanceHierarchy

public static Method[][] getMethodsSortedByInheritanceHierarchy(Class<?> theClass)

Returns all non-static methods declared by the specified class and its superclasses. The returned array contains the methods of all classes in the inheritance hierarchy, starting with the methods of the most general superclass, which is java.lang.Object.

Parameters:

theClass - the class whose methods are examined

Returns:

the array of method arrays
