All Implemented Interfaces:
ca.uqac.lif.cep.Contextualizable, ca.uqac.lif.cep.Duplicable, ca.uqac.lif.cep.DuplicableProcessor
public class RegexTupleBuilder extends ca.uqac.lif.cep.SynchronousProcessor
Builds a tuple out of parts of text. The parts of text to create the tuple from are specified by a regular expression.

More precisely, each element of the tuple corresponds to a capture block of the regex: the first capture block will correspond to the tuple's first element, the second to the second, and so on. By default, the name of each element is a number, with the first capture block starting at 0. Optionally, these elements can be renamed to arbitrary character strings.
