                                       String methodName,
                                       boolean strict,

                                throws IllegalArgumentException

Cherche une methode selon son nom et ses paramètres d'invocation.

Parameters:

klass - la classe dans laquelle rechercher la méthode

methodName - le nom de la méthode recherchée

strict - un drapeau pour déclancher une exception si la méthode n'est pas trouvée

arguments - les arguments d'invocation de la méthode

Returns:

la méthode trouvée

Throws:

IllegalArgumentException - si la méthode n'est pas trouvée et que le drapeau strict est à true

Since:

1.3.1

getDeclaredMethod

protected static Method getDeclaredMethod(Class<?> klass,
                                          String methodName,
                                          Set<Class<?>> visitedClasses,
                                          Object... arguments)

boxType

public static Class<?> boxType(Class<?> type)

Obtain the boxed type of any incoming type.

If incoming type is not a primitive type, then just returns himself.

Parameters:

type - the type to box

Returns:

the boxed type

Since:

1.3.1

getFieldAnnotation

public static <A extends Annotation> Map<Field,A> getFieldAnnotation(Class<?> objectClass,
                                                                     Class<A> annotationClass,

Obtain all the fields with the given annotation type.

Note: This method will scan deeply the given type if parameter deepVisit is setted to true.

Note: The type Object will not be scanned.

Type Parameters:

A - type of annotation to scan

Parameters:

objectClass - the type to scan

annotationClass - the type of annotation to scan

deepVisit - flag to visit deeply the class (if set to true, will also scan super classes and interfaces)

Returns:

the dictionnary of fields with the given annotation

Since:

2.0

Obtain all the methods with the given annotation type. Note: This method will scan deeply the given type if parameter deepVisit is setted to true. Note: The type Object will not be scanned.

Type Parameters:

A - type of annotation to scan

Parameters:

objectClass - the type to scan

annotationClass - the type of annotation to scan

deepVisit - flag to visit deeply the class (if set to true, will also scan super classes and interfaces)

Returns:

the dictionnary of methods with the given annotation

Since:

2.0
