Constructor Detail

AbstractContainerProperty

public AbstractContainerProperty(String name,
                                 GenericType<? extends V> type,
                                 Bean bean)

The constructor.

Parameters:

name - - see AbstractProperty.getName().

type - - see getType().

bean - - see AbstractProperty.getBean().

AbstractContainerProperty

public AbstractContainerProperty(String name,
                                 GenericType<? extends V> type,
                                 Bean bean,
                                 AbstractValidator<? super V> validator)

The constructor.

Parameters:

name - - see AbstractProperty.getName().

type - - see getType().

bean - - see AbstractProperty.getBean().

validator - - see AbstractValueProperty.validate().

AbstractContainerProperty

public AbstractContainerProperty(String name,
                                 GenericType<? extends V> type,
                                 Bean bean,
                                 Supplier<? extends V> expression)

The constructor.

Parameters:

name - - see AbstractProperty.getName().

type - - see getType().

bean - - see AbstractProperty.getBean().

expression - the Supplier providing the actual value.

Method Detail

getType

public GenericType<? extends V> getType()

Specified by:

getType in interface ReadableProperty<V>

Returns:

the type of the property value. Please note that the generic signature of this method is returning the type GenericType<? extends V> instead of GenericType <V> because JavaFx is binding the type Number for all numeric properties while e.g. IntegerProperty should be able to return GenericType<Integer> what is compatible with GenericType<? extends Number>.

sizeProperty

public ReadableIntegerProperty sizeProperty()

Specified by:

sizeProperty in interface ReadableContainerProperty<V>

Returns:

an ReadableIntegerProperty that represents the Collection.size() property of the container.

emptyProperty

public ReadableBooleanProperty emptyProperty()

Specified by:

emptyProperty in interface ReadableContainerProperty<V>

Returns:

an ReadableBooleanProperty that represents the empty property of the container.

invalidateProperties

protected void invalidateProperties()

Invalidates internal properties such as sizeProperty() and emptyProperty().
