Class PF_Range

java.lang.Object
org.apache.jena.sparql.pfunction.PropertyFunctionBase
org.aksw.jena_sparql_api.sparql.ext.number.PF_Range
All Implemented Interfaces:
org.apache.jena.sparql.pfunction.PropertyFunction
public class PF_Range extends org.apache.jena.sparql.pfunction.PropertyFunctionBase
Generate (big) integer numbers for the specified range start (inclusive) and end (exclusive). The default increment is 1 but can be optionally set to a different value. The forth argument is a displacement which is added to the start. It is a convenience feature to ease array access with certain offsets. Stepping must always be a positive value - 0 or negative values return a QueryIterNull. Examples: 
 (2, 6) number:range ?value # yields values { 2, 3, 4, 5 }
 (2, 6, 2) number:range ?value # yields {2, 4 }
