Bean-initializer

Bean-initializer is a Java utilitiy dedicated to help developers to initialize Objects with Complicated hierarchy .

Bean-initializer use only reflexive API , which make it easy to be integrated in java projects .

Getting Started

Example of use

• Create new Object with all subObjects

   City grenoble = BeanInitializer.createNew(City.class)
                    .withAllSubProperties();

• Create new Object with Type suppliers

   Country france = BeanInitializer.createNew(Country.class)
                    .withTypeSupplier(List.class, () -> new ArrayList<>()) // 'List' is an Interface
                    .withTypeSupplier(Double.class, () -> Double.valueOf(0)) // 'Double has no no argument constructor'
                    .withAllSubProperties();

• Create new Object with only fileds of classe

   Country france = BeanInitializer.createNew(Country.class)
                    .withOnlySubPropertiesWithClassName(Arrays.asList("City", "Coutry"));

• Create new Object with predicates on fields

   Predicate<Field> isPrivate = field -> !Modifier.isPrivate(field.getModifiers());
   Country france = BeanInitializer.createNew(Country.class)
                    .withOnlySubPropertiesAccordingToPredicates(Arrays.asList(isPrivate));

More examples are available on Test class.

Prerequisites

• Java 8
• no arg constructor
• TypeSupplier for Abstract classes ,interfaces or Types with no arg constructor (Example below)

    Country france = BeanInitializer.createNew(Country.class)
                      .withTypeSupplier(List.class, () -> new ArrayList<>()) // 'List' is Abstract type (Interface) 
                      .withTypeSupplier(Double.class, () -> Double.valueOf(0)) // 'Double' has no no argument constructor'
                      .withAllSubProperties();
