Method Detail

setParameter

public Set<NewGTFSError> setParameter(PreparedStatement preparedStatement,
                                      int oneBasedIndex,
                                      String string)

Specified by:

validateAndConvert

public ValidateFieldResult<String> validateAndConvert(String string)

Description copied from class: Field

Check the supplied string to see if it can be parsed as the proper data type. Perform any conversion (I think this is only done for times, to integer numbers of seconds). TODO should we really be converting times and dates to numbers or storing them as strings to simplify things?

Specified by:

validateAndConvert in class Field

Parameters:

string - a non-null String

Returns:

a string that is parseable as this field's type, or null if it is not parseable
