Constructor and Description |
---|
AggregatingFilter()
Creates a AggregatingFilter object.
|
AggregatingFilter(AggregationFunction func,
List params,
boolean asLiteral)
Sets the the function and the parameters of the property if function and
it's parameters are valid, otherwise false.
|
AggregatingFilter(boolean asLiteral)
Creates a AggregatingFilter object.
|
AggregatingFilter(String uri) |
Modifier and Type | Method and Description |
---|---|
List |
getFunctionParams()
Returns the list of the AggregationFunction parameters.
|
AggregationFunction |
getTheFunction()
Returns the AggregationFunction property.
|
boolean |
isWellFormed()
Returns true, if the PROP_uAAL_AGGREGATION_FUNCTION and
PROP_uAAL_AGGREGATION_PARAMS contain the required key.
|
boolean |
setProperty(String propURI,
Object value)
Adds a statement with this resource as the subject, the given
propURI as the predicate and the given value as the object. |
AggregatingFilter |
toLiteral()
Returns a copy of this filter that serializes as XML Literal.

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.
