Returns the value of the 'Slots' containment reference list. The list contents are of type Slot. It is bidirectional and its opposite is 'Instance'.

If the meaning of the 'Slots' containment reference list isn't clear, there really should be more of a description here...

the value of the 'Slots' containment reference list.

See Also:

MigrationPackage.getInstance_Slots(), Slot.getInstance()

getType

Type getType()

Returns the value of the 'Type' container reference. It is bidirectional and its opposite is 'Instances'.

If the meaning of the 'Type' container reference isn't clear, there really should be more of a description here...

The type container to which the instance belongs

Returns:

the value of the 'Type' container reference.

See Also:

Parameters:

value - the new value of the 'Type' container reference.

getReferences

org.eclipse.emf.common.util.EList<ReferenceSlot> getReferences()

Returns the value of the 'References' reference list. The list contents are of type ReferenceSlot. It is bidirectional and its opposite is 'Values'.

If the meaning of the 'References' reference list isn't clear, there really should be more of a description here...

The slots from which the instance is referenced

the value of the 'References' reference list.

See Also:

MigrationPackage.getInstance_References(), ReferenceSlot.getValues()

getUri

org.eclipse.emf.common.util.URI getUri()

Returns:

the value of the 'Uri' attribute.

See Also:

setUri(URI), MigrationPackage.getInstance_Uri()
