nameForHref

protected Name nameForHref(Name eObjectReferenceName)

Determine the name of the property that is used to hold the "href" URL literal value of the EObject reference.

The resulting name fits one of two patterns, depending upon whether the local part of the reference name is singular or plural. If singular, then the resulting name will have "Href" appended to the local part of the supplied name. If plural, then the resulting name will consist of the singularlized local part appended with "Hrefs". In all cases, the namespace URI of the resulting name will match that of the supplied name.

Parameters:

eObjectReferenceName - the name of the normal EObject reference property, which is typically a href

Returns:

the name

nameForResolvedReference

protected Name nameForResolvedReference(Name eObjectReferenceName)

Determine the name of the property that is used to hold the WEAKREFERENCE values for the resolved EObject reference.

This method just returns the name without modification.

Parameters:

eObjectReferenceName - the name of the normal EObject reference property, which is typically a href

Returns:

the name

nameForResolvedName

protected Name nameForResolvedName(Name eObjectReferenceName)

Determine the name of the property that is used to hold the name(s) for the resolved EObject reference.

The resulting name fits one of two patterns, depending upon whether the local part of the reference name is singular or plural. If singular, then the resulting name will have "Name" appended to the local part of the supplied name. If plural, then the resulting name will consist of the singularlized local part appended with "Names". In all cases, the namespace URI of the resulting name will match that of the supplied name.

Parameters:

eObjectReferenceName - the name of the normal EObject reference property, which is typically a href

Returns:

the name

nameForResolvedId

protected Name nameForResolvedId(Name eObjectReferenceName)

Determine the name of the property that is used to hold the identifier(s) for the resolved EObject reference.

The resulting name fits one of two patterns, depending upon whether the local part of the reference name is singular or plural. If singular, then the resulting name will have "XmiUuid" appended to the local part of the supplied name. If plural, then the resulting name will consist of the singularlized local part appended with "XmiUuids". In all cases, the namespace URI of the resulting name will match that of the supplied name.

Parameters:

eObjectReferenceName - the name of the normal EObject reference property, which is typically a href

Returns:

the name

stringFrom

protected String stringFrom(Object value)

shortenName

protected Name shortenName(Name name)

uuidFor

protected UUID uuidFor(Node node)

xmiUuidFor

protected UUID xmiUuidFor(Node node)

references

protected List<UUID> references(Property property)

Extracts the "mmuuid" values from the property if the property is indeed an XMI reference to local objects.

Parameters:

property - the property

Returns:

the list of mmuuid values, or null if this property does not contain any references; never empty
