Converts reference property into exportable format and adds it to the exportable object

Parameters:

dbObjectProperties - Map of object properties

object - Object in exportable format to which reference will be added

type - Type of the column

columnName - Column name in DB

propertyName - Property name

convertToObjectsReadyForSerialisation

public List<EntityObjectReadyForExport> convertToObjectsReadyForSerialisation(List<DbRawObjectData> dbObjectsProperties)

Specified by:

convertToObjectsReadyForSerialisation in interface Converter

convertToLong

public static Long convertToLong(Object value)

SQL server and Oracle returns BigDecimal objects (not Long), so it has to be fixed first.

convertToInteger

public static Integer convertToInteger(Object value)

Oracle server returns BigDecimal objects (not Integer), so it has to be fixed first.

convertToBoolean

public static @Nullable Boolean convertToBoolean(Object value)

Some databases return boolean values as "T" and "F" If value is a string, best efforts to convert it to "true" or "false" will be made. ("T", "F", "yes", "no", etc.) If no match is made, null is returned. See BooleanUtils.html#toBoolean-java.lang.String
