Field Details

typeMapper

protected org.apache.jena.datatypes.TypeMapper typeMapper

typeDecider

protected TypeDecider typeDecider

viewClass

protected Class<T> viewClass

polymorphicOnly

protected boolean polymorphicOnly

enableCanAsCheck

protected boolean enableCanAsCheck

If true, checks via Resource.canAs(viewClass) are performed. For mapping purposes, it seems better to avoid the check because viewClass's implementation may requires triples to exist which may prevent creation of the view that would add those triples.

nodeMapper

protected transient NodeMapper<T> nodeMapper
