Method Detail

newInstance

public static <E> E newInstance(Class<E> clazz,

                                boolean nullIfMissing)

Invoke constructor on clazz to create new instance. Try to find argument for constructor in args parameter.

Type Parameters:

E - FIXME

Parameters:

clazz - class of object to instantiate

args - all possible parameter that constructor can used

nullIfMissing - if no suitable class or object found in args, use null value (no exception)

Returns:

new instance

Throws:

IllegalArgumentException - if something is wrong during instantiation

choiceArgument

public static Object choiceArgument(Class<?> clazz,
                                    List args,
                                    boolean nullIfMissing)

Permet de matcher un type d'argument attendu clazz parmi un ensemble possible de candidat. Les candidats peuvent etre des classes qu'il faudra instancier pour satisfaire le type demande.

Parameters:

clazz - le type recherché

args - la liste des arguments ou des types

nullIfMissing - pour retourner nulle si l'argument n'est pas trouvé

Returns:

le type d'argument trouvé

getMethod

public static List<Method> getMethod(Class<?> clazz,
                                     String methodName,
                                     boolean ignoreCase)

Get all methods with name given in argument without check parameters.

Parameters:

clazz - where to search method

methodName - method name to search

ignoreCase - if true, ignore difference in method name case

Returns:

list of detected methods

getMethod

public static List<Method> getMethod(String name,
                                     boolean ignoreCase)

List method that match name, name must be [package.][class][#][method] if package, class or method missing, exception throw

Parameters:

name - name of the method

ignoreCase - check exact method name if false

Returns:

list of method that match name

call

public static Object call(Object o,
                          Method m,
                          String... params)
                   throws IllegalAccessException,
                          IllegalArgumentException,
                          InvocationTargetException,
                          InstantiationException

Call method m with params as String. Each param is converted to required type for method with beanutils converter

Parameters:

o - object where method must be call

m - method to call

params - parameters for method call

Returns:

returned method's value

Throws:

IllegalAccessException - FIXME

IllegalArgumentException - FIXME

InvocationTargetException - FIXME

InstantiationException - FIXME

convert

public static Object convert(String v,
                             Class<?> clazz)
