Class DuplicityCheckerIndexCreator

java.lang.Object

org.egothor.duplicity.apps.DuplicityCheckerIndexCreator

public class DuplicityCheckerIndexCreator
extends Object

Use this program to create index with duplicity checking ability from barrels saved locally. There are three possible variants:

• createIndex - create index WITHOUT duplicity checking ability from given barrels, directory containing barrels must be specified
• createDCIndex - create index WITH duplicity checking ability from given barrels, directory containing barrels must be specified
• addDC - add duplicity checking ability to given index, barrels will be taken from the index

No duplicates are searched in the documents, i.e., all the documents in the barrels are added to the index. Usage: java DuplicityCheckerIndexCreator createIndex|createDCIndex|addDC indexDir [-b barrelsDir] [-s startBarrel] [-e endBarrel] [-c className] [-noprompt] indexDir: directory where the index should be created barrelsDir: directory where the barrels are located, will be ignored in addDC mode must be specified for createIndex and createDCIndex modes startBarrel: number of barrel from which the duplicity checker initialization should begin default = 1 endBarrel: number of barrel up to which the duplicity checker initialization should go default = last barrel number className: name of the class to be used to parse the barrels in the index, must implement the BarrelReader interface and have a one String parameter constructor will be ignored in the addDC mode default = org.egothor.robot.index.ThickFastIn noprompt: the application does not prompt the user for anything Examples: java DuplicityCheckerIndexCreator createIndex index -b barrels - Creates index in directory index using all barrels found in the directory barrels. java DuplicityCheckerIndexCreator createDCIndex indexDC -b barrels -e 10 - Creates duplicity checking index in directory indexDC using first 10 barrels found in the directory barrels. java DuplicityCheckerIndexCreator addDC index - Adds duplicity checking ability to the index in directory index. INFO: Currently the only class that meets all the conditions (has a one String parameter constructor and provides resolved documents) is the default class.
