Interface Summary

Interface	Description
EntityPopulator<T>	For now we will copy all available fields into Java model objects.
TableReader<T extends Entity>	This is an interface for classes that can iterate over all entities in a single GTFS table, or fetch single entities by ID, or fetch ordered groups of entities with the same ID (e.g.
TableWriter<T extends Entity>	This is an interface for classes to create, update, or delete a GTFS entity given an Integer ID and/or JSON string.

Class Summary

Class	Description
BatchTracker	Avoid Java's "effectively final" nonsense when using prepared statements in foreach loops.
BooleanField	A GTFS boolean field, coded as a single character string 0 or 1.
ColorField	Represents a six-digit hex color code.
CSVResultSetAdapter	This makes an incoming row of a CSV file resemble a Result object.
CurrencyField
DateField	A GTFS date in the format YYYYMMDD.
DateListField	Field type for a list of date strings.
DoubleField	Created by abyrd on 2017-03-31
Feed	This connects to an SQL RDBMS containing GTFS data and lets you fetch elements out of it.
FeedLoadResult	An instance of this class is returned by the GTFS feed loading method.
Field	Field subclasses process an incoming String that represents a single GTFS CSV field value.
IllegalCharacter	This class contains a convenient way to describe illegal character sequences during GTFS feed loading, as well as the appropriate replacement value and a human-readable description (rather than inputting the bad sequence into the database and having to deal with downstream issues).
IntegerField
JdbcGtfsExporter	Handles exporting a feed contained in the database to a GTFS zip file.
JdbcGTFSFeedConverter	This class loads a MapDB-based GTFSFeed into an RDBMS.
JdbcGtfsLoader	This class loads CSV tables from zipped GTFS into an SQL relational database management system with a JDBC driver.
JdbcGtfsSnapshotter	This class takes a feedId that represents a feed already in the database and creates a copy of the entire feed.
JDBCTableReader<T extends Entity>	This wraps a single database table and provides methods to load its rows into Java objects, iterate over the contents of the table, and select individual rows.
JdbcTableWriter	This wraps a single database table and provides methods to modify GTFS entities.
LanguageField	Checks a BCP47 language tag.
ReferenceTracker	This class is used while loading GTFS to track the unique keys that are encountered in a GTFS feed.
ShortField	Created by abyrd on 2017-03-31
SnapshotResult	This contains the result of a feed snapshot operation.
SQLEntityFetcher<T>	Created by abyrd on 2017-04-04
StringField	Created by abyrd on 2017-03-31
StringListField	Field type for a list of strings.
Table	This groups a table name with a description of the fields in the table.
TableLoadResult	An instance of this class is returned by the method that loads a single GTFS table.
TimeField	A field in the format HH:MM:SS, which will be stored as a number of seconds after midnight.
URLField	Created by abyrd on 2017-03-31
ValidateFieldResult<T>	This mini helper class is used during feed loading to return both: - a cleaned value of arbitrary type T and - any errors encountered while validating the original value.

Enum Summary

Enum	Description
Requirement	These are field requirement levels, which should be assigned accordingly to any fields within a Table to determine if a field is requisite for a specific purpose.
