Constructor Detail

GenericProperty

public GenericProperty(String name,
                       GenericType<V> type,
                       Bean bean)

The constructor.

Parameters:

name - - see AbstractProperty.getName().

type - - see getType().

bean - - see AbstractProperty.getBean().

GenericProperty

public GenericProperty(String name,
                       GenericType<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().

GenericProperty

public GenericProperty(String name,
                       GenericType<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<V> getType()

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>.

doGetValue

protected V doGetValue()

Specified by:

doGetValue in class AbstractValueProperty<V>

Returns:

the internal value.

doSetValue

protected boolean doSetValue(V newValue)

Description copied from class: AbstractValueProperty

Called from AbstractValueProperty.setValue(Object).

Specified by:

doSetValue in class AbstractValueProperty<V>

Parameters:

newValue - the new value to set.

Returns:

true if the value has changed, false otherwise.

withValdidator

public ObjectValidatorBuilder<? extends V,? extends AbstractProperty.PropertyBuilder<? extends GenericProperty<? extends V>>,?> withValdidator()

Specified by:

withValdidator in class AbstractProperty<V>

Returns:

a new builder for the validator of this property with a parent-builder to create a AbstractProperty.copy(AbstractValidator) of this property with the configured validator.

toJson

protected void toJson(javax.json.stream.JsonGenerator json,
                      V propertyValue)

Specified by:

toJson in class AbstractProperty<V>

Parameters:

json - the JsonGenerator.

propertyValue - the value.

See Also:

AbstractProperty.toJson(JsonGenerator)

fromJson

public void fromJson(javax.json.stream.JsonParser json)

Description copied from interface: JsonSupport

Deserializes this object from JSON (JavaScript-Object-Notation). This operation is typically NOT symmetric to JsonSupport.toJson(JsonGenerator) - e.g. JsonSupport.toJson(JsonGenerator) might write a property with its value while JsonSupport.fromJson(JsonParser) may only deserialze the value as the parent object has to handle the property names that may appear in any order.

Parameters:

json - the JsonParser to read from.
