me.vertretungsplan.parser.CSVParser

All Implemented Interfaces:

SubstitutionScheduleParser

public class CSVParser
extends BaseParser

Generic parser for substitution schedules in CSV format.

This parser can be accessed using "csv" for SubstitutionScheduleData.setApi(String).

Configuration parameters

These parameters can be supplied in SubstitutionScheduleData.setData(JSONObject) to configure the parser:

url (String, required)

The url of the CSV file to be fetched

separator (String, required)

The separator used in the CSV file (such as ",", ";" or "\t")

columns (Array of Strings, required)

The order of columns used in the CSV file. Entries can be: "lesson", "subject", "previousSubject", "type", "type-entfall", "room", "previousRoom", "teacher", "previousTeacher", desc", "desc-type", "class", "day", "stand", "ignore"

classes (Array of Strings, required if classesUrl not specified)

The list of all classes, as they can appear in the schedule

website (String, recommended)

The URL of a website where the substitution schedule can be seen online

skipLines (Integer, optional)

The number of lines to skip at the beginning of the CSV file. Default: 0

classesUrl (String, optional)

The URL of an additional CSV file containing the classes, one per line

classRegex (String, optional)

RegEx to modify the classes set on the schedule (in getSubstitutionSchedule(), not getAllClasses(). The RegEx is matched against the class using Matcher.find(). If the RegEx contains a group, the content of the first group Matcher.group(int) is used as the resulting class. Otherwise, Matcher.group() is used. If the RegEx cannot be matched (Matcher.find() returns false), the class is set to an empty string.

Additionally, this parser supports the parameters specified in LoginHandler for login-protected schedules.
