Method Detail

modelToApplication

public Object modelToApplication(Serializable modelValue)

Description copied from interface: ModelType

Creates a representation of the provided model value that is intended for use in application code. For mutable values, this is typically a proxy that is directly connected to the underlying model value.

Specified by:

modelToApplication in interface ModelType

Parameters:

modelValue - the model value to convert

Returns:

a user-friendly representation of the provided model value

applicationToModel

public Serializable applicationToModel(Object applicationValue,
                                       PropertyFilter filter)

Description copied from interface: ModelType

Creates a model value representation of the provided application value.

For application values that contain properties (i.e. beans), the provided filter is used to determine which properties from the bean should be included in the model representation.

Specified by:

applicationToModel in interface ModelType

Parameters:

applicationValue - the user value to convert

filter - the filter to use to determine which properties to include, not null

Returns:

a model value representation of the provided user value.

accepts

public boolean accepts(Type applicationType)

Description copied from interface: ModelType

Checks whether this type can accept application values of the given type. The method only considers this actual type, not the types of sub properties or list items.

Specified by:

accepts in interface ModelType

Parameters:

applicationType - the application type to check, not null

Returns:

true if the provided type is acceptable, false otherwise

getJavaType

public Type getJavaType()

Description copied from interface: ModelType

Gets the Java Type that this model encapsulates.

Specified by:

getJavaType in interface ModelType

Returns:

the java type

toJson

public elemental.json.JsonValue toJson()

Description copied from interface: ModelType

Creates a JSON representation of this model type.

Specified by:

toJson in interface ModelType

Returns:

a JSON representation of this model type, not null

createInitialValue

public void createInitialValue(StateNode node,
                               String property)

Description copied from interface: ModelType

Create initial value for the given property and set it for the node.

Specified by:

createInitialValue in interface ModelType

Parameters:

node - the node where the initial value should be set the property

property - the property in the node whose initial value needs to be created

getWrappedModelType

public ModelType getWrappedModelType()

Gets the model type describing the data actually stored in the model.

Returns:

the wrapped model type
