Resource
Resource.PROP_SERIALIZATION_OPTIONAL
,
Resource.PROP_SERIALIZATION_REDUCED
, or Resource.PROP_SERIALIZATION_FULL
.
It can be assumed that the given property is one of those returned by
Resource.getPropertyURIs()
. PROP_SERIALIZATION_OPTIONAL
in
favor of lower communication traffic and higher performance even at risk
of a possible additional query on the receiver side for fetching this
info. With the same rationale, if a property should be included in the
process of serialization, it is preferable to include it in a reduced
form; in this case the return value should be
PROP_SERIALIZATION_REDUCED
, otherwise
PROP_SERIALIZATION_FULL
can be returned.
Subclasses should normally overwrite this method as this default
implementation returns always PROP_SERIALIZATION_FULL
.

Subclasses should overwrite this methods as the default implementation returns always true.
isWellFormed
in class Resource
Resource.isWellFormed()
public boolean setProperty(String propURI, Object value)
Resource
propURI
as the predicate and the given value as the object.
Subclasses must override this in order to decide if the statement to be
added fits the general class constraints. If not, the call of this method
should be ignored. For each property only one single call may be made to
this method, unless subsequent calls to this method for setting the value
of the same property are treated as an update for an update-able
property. Multi-valued properties must be set using an instance of
List
. The differentiation, if a such list should be
treated as an rdf:List, can be made with the help of
Resource.isClosedCollection(String)
. The default implementation here
accepts all property-value pairs blindly except for rdf:type which is
handled if the value is a type URI, a Resource or a java.util.List of
them.
Note: The setting of the property rdf:type is being handled by this class
via the final methods Resource.addType(String, boolean)
,
Resource.getType()
, and Resource.getTypes()
. Although these methods give
the view of handling type URIs as strings, but in reality the types are
stored as direct instances of this class. So, the subclasses should
ignore calls for setting rdf:type; if not, then the subclass must pay
attention that the value should be a List
of direct instances of
this class so that (1) the Resource.toString()
method returns just the
URI and (2) the serializers get no problems with the value. Also,
settings via subclasses may be overwritten by this class if a subsequent
call to Resource.addType(String, boolean)
is made.
