Method Detail

getAllDeclaredFields

public static Set<Field> getAllDeclaredFields(Class<?> _class,
                                              String... _fieldsToIgnore)

NOTE: Accessibility of Fields returned in the Set have not been changed (setAccessable(true) is NOT called explicitly)!

Parameters:

_class -

_fieldsToIgnore -

Returns:

null if _class was null, Set otherwise

getAllDeclaredStaticFields

public static Set<Field> getAllDeclaredStaticFields(Class<?> _class,
                                                    String... _fieldsToIgnore)

Does what getAllDeclaredFields(Class, String...) does, but filters all non-static fields.

Parameters:

_class -

_fieldsToIgnore -

Returns:

getAllDeclaredNonStaticFields

public static Set<Field> getAllDeclaredNonStaticFields(Class<?> _class,
                                                       String... _fieldsToIgnore)

Does what getAllDeclaredFields(Class, String...) does, but filters all static fields.

Parameters:

_class -

_fieldsToIgnore -

Returns:

getAllDeclaredFieldsAnnotatedWithAny

@SafeVarargs
public static Set<Field> getAllDeclaredFieldsAnnotatedWithAny(Class<?> _class,
                                                                           Class<? extends Annotation>... _annotations)
