Method Detail

getId

public String getId()

Frequency entries have no ID in GTFS so we define one based on the fields in the frequency entry. It is possible to have two identical frequency entries in the GTFS, which under our understanding of the situation would mean that two sets of vehicles were randomly running the same trip at the same headway, but uncorrelated with each other, which is almost certain to be an error.

Overrides:

getId in class Entity

Returns:

a key that according to the GTFS spec should uniquely identify this entity, either alone or together with a sequence number. For example stop_times and shapes have no single field that uniquely identifies a row, and the stop_sequence or shape_pt_sequence must also be considered.

setStatementParameters

public void setStatementParameters(PreparedStatement statement,
                                   boolean setDefaultId)
                            throws SQLException

Sets the parameters for a prepared statement following the parameter order defined in Table.FREQUENCIES. JDBC prepared statement parameters use a one-based index.

Specified by:

setStatementParameters in class Entity

Throws:

SQLException

compareTo

public int compareTo(Frequency o)

must have a comparator since they go in a navigable set that is serialized

Specified by:

compareTo in interface Comparable<Frequency>
