public boolean isOfType(Object instance,
 String metaClass)
                 throws EolModelElementTypeNotFoundException

Specified by:

isOfType in interface IModel

Overrides:

isOfType in class Model

Throws:

EolModelElementTypeNotFoundException

getElementById

public Object getElementById(String id)

Specified by:

getElementById in interface IModel

getElementId

public String getElementId(Object instance)

Specified by:

getElementId in interface IModel

setElementId

public void setElementId(Object instance,
 String newId)

Specified by:

setElementId in interface IModel

getEnumerationValue

public Object getEnumerationValue(String enumeration,

                           throws EolEnumerationValueNotFoundException

Specified by:

getEnumerationValue in interface IModel

Throws:

EolEnumerationValueNotFoundException

getTypeOf

public Object getTypeOf(Object instance)

Specified by:

getTypeOf in interface IModel

Overrides:

getTypeOf in class Model

getTypeNameOf

public String getTypeNameOf(Object instance)

Description copied from interface: IModel

Returns a string representing the type of the instance object. The value returned by this function can be passed to createInstance to instantiate another object of the same type as instance.

Specified by:

getTypeNameOf in interface IModel

Parameters:

instance - The model object whose type is to be determined.

Returns:

the name of the type of the model object, instance.

hasType

public boolean hasType(String type)

Specified by:

hasType in interface IModel

hasPackage

public boolean hasPackage(String packageName)

Description copied from interface: IReflectiveModel

Returns true iff this model contains a package with the given name. In general, a "package" is a group of types (and potentially other packages) and a namespace for the grouped elements. The precise semantics of "package" is specific to the implementation. For example, an Ecore implementation might use EPackage. An XML implementation might use XML namespaces. A CSV implementation might not support any notion of packages (and hence always return false).

Specified by:

hasPackage in interface IReflectiveModel

getContainerOf

public Object getContainerOf(Object object)

Description copied from interface: IReflectiveModel

Returns the model element that contains the given model element, or null if the given model element is top-level.

Specified by:

getContainerOf in interface IReflectiveModel

Parameters:

object - The model element whose container is to be found.

Returns:

the model element that contains object, or null if object is not contained in any other model element.

isInstantiable

public boolean isInstantiable(String type)

Specified by:

isInstantiable in interface IModel

getPropertiesOf

public Collection<String> getPropertiesOf(String type)
                                   throws EolModelElementTypeNotFoundException

Description copied from interface: IReflectiveModel

Returns a collection containing all of the properties that instances of type know about.

Specified by:

getPropertiesOf in interface IReflectiveModel

Parameters:

type - The type of model object whose properties are to be determined.

Returns:

all of the properties that instances of type knows about.

Throws:

EolModelElementTypeNotFoundException - when this model has no such type

hasProperty

public boolean hasProperty(String type,
 String property)
                    throws EolModelElementTypeNotFoundException

Specified by:

hasProperty in interface IReflectiveModel

Throws:

EolModelElementTypeNotFoundException

public IReflectivePropertySetter getPropertySetter()

Specified by:

getPropertySetter in interface IModel

Specified by:

getPropertySetter in interface IReflectiveModel

Overrides:

getPropertySetter in class Model

isModelElement

public boolean isModelElement(Object instance)

Description copied from interface: IModel

Specified by:

isModelElement in interface IModel

Overrides:

isModelElement in class Model

Parameters:

instance - the Java object to test.

Returns:

true if and only if instance can be contained by this model.

isEnumerationValue

Description copied from interface: IReflectiveModel

Returns true iff object is an enumeration value.

Specified by:

isEnumerationValue in interface IReflectiveModel

getEnumerationTypeOf

public String getEnumerationTypeOf(Object literal)
                            throws EolNotAnEnumerationValueException

Description copied from interface: IReflectiveModel

Returns the name of the enumeration type of the literal parameter.

Specified by:

getEnumerationTypeOf in interface IReflectiveModel

Throws:

EolNotAnEnumerationValueException - when literal is not an enumeration value

getEnumerationLabelOf

public String getEnumerationLabelOf(Object literal)
                             throws EolNotAnEnumerationValueException

Description copied from interface: IReflectiveModel

Returns the enumeration label of the literal parameter.

Specified by:

getEnumerationLabelOf in interface IReflectiveModel

Throws:

EolNotAnEnumerationValueException - when literal is not an enumeration value

preventLoadingOfExternalModelElements

public boolean preventLoadingOfExternalModelElements()

Description copied from interface: IReflectiveModel

Prevents the loading of model elements that are referenced by this model but are not contained in this model. This is useful for clients, such as Epsilon Flock, which create a clone or conservative copy of this model.

Specified by:

preventLoadingOfExternalModelElements in interface IReflectiveModel

Returns:

true iff this method had an effect (i.e. when this model supports external references, was configured to load external references and is no longer configured to load external references).

load

public void load()
          throws EolModelLoadingException

Specified by:

load in interface IModel

Throws:

EolModelLoadingException

owns

public boolean owns(Object instance)

Description copied from interface: IModel

Used to test whether an object is contained in this model.

Specified by:

owns in interface IModel

Parameters:

instance - the Java object to test.

Returns:

true if and only if instance is contained by this model.

store

public boolean store(String location)

Specified by:

store in interface IModel

store

public boolean store()

Specified by:

store in interface IModel
