Field Detail

IS_IRRELEVANT_BUT_NOT_EMPTY

public static final java.util.function.Predicate<ModelObjectAttribute> IS_IRRELEVANT_BUT_NOT_EMPTY

The Predicate used in resetIrrelevantAttributes(IModelObject). Can be combined via and/or with other predicates to refine the criteria passed to resetAttributes(IModelObject, Predicate).

Method Detail

of

public static java.util.List<ModelObjectAttribute> of(IModelObject modelObject)

Collects all ModelObjectAttributes of the given model object.

ofIncludingChildren

public static java.util.List<ModelObjectAttribute> ofIncludingChildren(IModelObject modelObject)

Collects all ModelObjectAttributes of the given model object and its children.

resetIrrelevantAttributes

public static java.util.List<ModelObjectAttribute> resetIrrelevantAttributes(IModelObject modelObject)

Clears irrelevant attributes of a IModelObject and its dependent model-objects.

If an attribute implements NullObjectSupport the NullObject is used, String-attributes are set to an empty string. Otherwise null is used to clear the attribute.

For each cleared attribute a ModelObjectAttribute is returned. It's ModelObjectAttribute.toObjectProperty() method may be used to generate Messages about the change.

Parameters:

modelObject - the object to clear

Returns:

a list of ModelObjectAttributes that were cleared

resetAttributes

public static java.util.List<ModelObjectAttribute> resetAttributes(IModelObject modelObject,
                                                                   java.util.function.Predicate<ModelObjectAttribute> shouldReset)

Clears attributes of a IModelObject and its dependent model-objects that match the given Predicate.

If an attribute uses one of the NullObjectSupport-datatypes Decimal and Money, the NullObject is used, String-attributes are set to an empty string. Otherwise null is used to clear the attribute.

For each cleared attribute a ModelObjectAttribute is returned. It's ModelObjectAttribute.toObjectProperty() method may be used to generate Messages about the change.

Parameters:

modelObject - the object to clear

shouldReset - a Predicate deciding which attributes to reset.

Returns:

a list of ModelObjectAttributes that were cleared
