Method Detail

convert

public void convert(java.lang.String inputFile,
                    java.lang.String outputFile)
             throws java.io.IOException

Read a sequence database in SPMF format, add timestamps and then write the sequence database to a file. Note that this code could be further optimized if performance is an issue (instead of loading the file into memory, it could be loaded line by line).

Parameters:

inputFile - the path of a sequence database in SPMF format

outputFile - the output path for writing the database with timestamps

Throws:

java.io.IOException - if error while reading/writing file
