Method Details

init(self, db, dbType, logFile)
(Constructor)

Initialize database pointer, cursor, db type (MySQL or SQLite). Retrieve information about table names from underlying DB.

Overrides:: es_init.ESInit.__init__ (inherited documentation)

dumpInfo(self, timeStamp)

Dump EventStore DB content in user readable format. It uses sql_util module to do the job.

dumpRuns(self, minRun, maxRun)

dumpShowDepend(self, childName)

Show all dependencies for given data version name. It uses sql_util module to do the job.

dumpTable(self, dbTable)

Prints table content. It uses sql_util module to do the job.

dumpTableSchema(self, tableName)

Prints table schema. It uses sql_util module to do the job.

findFile(self, searchRun)

Find file(s) associated with given run. It uses sql_util module to do the job.
