getTypeNameOf

public java.lang.String getTypeNameOf(java.lang.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(java.lang.String type)

Specified by:

hasType in interface IModel

hasPackage

public boolean hasPackage(java.lang.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 java.lang.Object getContainerOf(java.lang.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(java.lang.String type)

Specified by:

isInstantiable in interface IModel

getPropertiesOf

public java.util.Collection<java.lang.String> getPropertiesOf(java.lang.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:

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 java.lang.String getEnumerationLabelOf(java.lang.Object literal)
                                       throws EolNotAnEnumerationValueException

Description copied from interface: IReflectiveModel

Returns the enumeration label of the literal parameter.

preventLoadingOfExternalModelElements

public boolean preventLoadingOfExternalModelElements()

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).

public boolean store()

Specified by:
