getFullyQualifiedTypeNameOf

public String getFullyQualifiedTypeNameOf(Object instance)

Description copied from interface: IModel

Returns a string representing the fully-qualified 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:

getFullyQualifiedTypeNameOf 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.

isModelElement

public boolean isModelElement(Object instance)

Description copied from interface: IModel

Used to test whether a Java object can be contained by this model. For example, EMF models can contain instances of EObject, but not instances of just Object.

Specified by:

isModelElement in interface IModel

Parameters:

instance - the Java object to test.

Returns:

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

getTypeOf

public Object getTypeOf(Object instance)

Specified by:

getTypeOf in interface IModel

isReadOnLoad

public boolean isReadOnLoad()

Specified by:

isReadOnLoad in interface IModel

isStoredOnDisposal

public boolean isStoredOnDisposal()

Specified by:

isStoredOnDisposal in interface IModel

setReadOnLoad

public void setReadOnLoad(boolean readOnLoad)

Specified by:

setReadOnLoad in interface IModel

setStoredOnDisposal

public void setStoredOnDisposal(boolean storedOnDisposal)

Specified by:

setStoredOnDisposal in interface IModel

getPropertyGetter

public IPropertyGetter getPropertyGetter()

Specified by:

getPropertyGetter in interface IModel

getPropertySetter

public IPropertySetter getPropertySetter()

Specified by:

getPropertySetter in interface IModel

dispose

public void dispose()

Specified by:

dispose in interface IModel

knowsAboutProperty

public boolean knowsAboutProperty(Object instance,
 String property)

Description copied from interface: IModel

Returns true if this instance could have this property at some point.

Specified by:

public Metamodel getMetamodel(StringProperties properties,
 IRelativePathResolver resolver)

Specified by:

getMetamodel in interface IModel

isPropertySet

public boolean isPropertySet(Object instance,
 String property)
                      throws EolRuntimeException

Description copied from interface: IModel

Returns true if this instance has an explicit value for this property. This would be equivalent to eIsSet in EMF.

Specified by:

isPropertySet in interface IModel

Throws:

EolRuntimeException
