Package ca.uqac.lif.cep.tuples

Class MergeScalars

  • All Implemented Interfaces:
    ca.uqac.lif.azrael.Printable, ca.uqac.lif.azrael.Readable, ca.uqac.lif.cep.Duplicable, ca.uqac.lif.cep.functions.DuplicableFunction
    public class MergeScalars
extends ca.uqac.lif.cep.functions.Function
    Creates a named tuple out of multiple input traces, each containing scalar values. For example, if p1 and p2 are two processors that return numbers, one can create a trace of tuples with attributes "foo" and "bar", where foo is the value of the event in p1 and bar is the value of the event in p2, by writing: 
     FunctionProcessor fp = new FunctionProcessor(new MergeScalars("foo", "bar"));
 Connector.connect(p1, 0, fp, 0);
 Connector.connect(p2, 0, fp, 1);
