template<typename DataType >

void kanzi::PropertyObject::setProperty	(	const PropertyType< DataType > &	propertyType,
		typename PropertyType< DataType >::Traits::ParameterType	value
	)

inline

Sets the local value of a property type.

Parameters

propertyType	The property type identifying the property to set.
value	The value to set.

void kanzi::PropertyObject::removeKzbProperties ( flat_set< AbstractPropertyType > * keepProperties )

Remove all KZB properties that are not included in a given set.

Property types marked with KZU_PROPERTY_MANAGER_FLAG_KEEP_DURING_PATCHING are not removed.

Parameters

keepProperties Set of properties to keep.

void kanzi::PropertyObject::removeKzbProperties ( )

inline

Remove all KZB properties.

Property types marked with KZU_PROPERTY_MANAGER_FLAG_KEEP_DURING_PATCHING are not removed.

template<typename DataType >

PropertyType<DataType>::Traits::ReturnType kanzi::PropertyObject::getProperty ( const PropertyType< DataType > & propertyType ) const

inline

Returns the current value of a property type.

This function returns a value that is the result of the property system evaluating the inputs that can affect the values of properties. It calculates the final value by determining the base value of the property and applying existing modifiers to it.

Base value is affected by the following inputs where the highest entry in the list determines the base value:

Local value set with setProperty or loaded from kzb
Value set by a style affecting the property.
Value defined by class metadata.

When the base value is determined the system applies modifiers to the value that can change the value or replace it completely. The following is the list of possible modifiers, where the order of evaluation is determined by the order the modifiers were added or applied.

Values defined is states of state manager.
Animations.

If no inputs to the property value can be established the system returns the value registered in the property type metadata.

Parameters

propertyType The property type identifying the property to retrieve.

Returns: Returns the evaluated property value.

template<typename DataType >

optional<typename PropertyType<DataType>::Traits::ReturnType> kanzi::PropertyObject::getOptionalProperty ( const PropertyType< DataType > & propertyType ) const

inline

Evaluates the property value in the same way as the overload above but does not default to the value in property metadata if there are no inputs to the property value.

If there is no value sources or modifiers, nullopt is returned.

See also: getProperty()

Parameters

propertyType The property type identifying the property to retrieve.

Returns: Returns an optional value that is left empty if the property was not found.

template<typename DataType >

PropertyType<DataType>::Traits::ReturnType kanzi::PropertyObject::getPropertyBase ( const PropertyType< DataType > & propertyType ) const

Local value set with setProperty or loaded from kzb
Value set by a style affecting the property.
Value defined by class metadata.

Modifiers are not applied, the highest-priority base value is returned.

If no inputs to the property value can be established the system returns the value default value from property type metadata.

Parameters

propertyType The property type identifying the property to retrieve.

Returns: Returns the evaluated property value.

template<typename DataType >

optional<typename PropertyType<DataType>::Traits::ReturnType> kanzi::PropertyObject::getOptionalPropertyBase ( const PropertyType< DataType > & propertyType ) const

See also: getPropertyBase()

If no inputs to the property value can be established the system returns the value default value from property type metadata.

Parameters
