Class SequenceDatabase

java.lang.Object

ca.pfv.spmf.algorithms.sequentialpatterns.fournier2008_seqdim.SequenceDatabase

public class SequenceDatabase
extends java.lang.Object

Implementation of a sequence database as used by the SeqDim and Fournier-Vier (2008) algorithms. Each sequence need to hvae a unique ID. See examples in the /test/ directory for the format of input files. that can be read by this class.
