Class SequenceDatabase

java.lang.Object

ca.pfv.spmf.algorithms.sequentialpatterns.clasp_AGP.dataStructures.database.SequenceDatabase

public class SequenceDatabase
extends java.lang.Object

Inspired in SPMF. Implementation of a sequence database. Each sequence should have a unique id. See examples in /test/ directory for the format of input files.
