something similar right?"
This is exactly what I have done. The name of the package is provided as
parameter to the DataFormat class. Next, using reflection/introspection the
classes of the model are retrieved. I have implemented something simple but
we can bind one or several classes to a CSV record.
ex :
public class Client {
@DataField(name = "ClientNumber", pos = 1, formatType =
"java.lang.String")
public String clientNr;
@DataField(name = "firstName", pos = 2, formatType =
"java.lang.String")
public String FirstName;
@DataField(name = "lastName", pos = 3, formatType = "java.lang.String")
public String LastName;
@Record(separator =",", name = "Order")
public class Order {
@DataField(name = "Number", pos = 0, formatType = "java.lang.Integer")
public int orderNr;
@LinkField( from = "com.xpectis.csv.model.Order", to =
"com.xpectis.csv.model.Client", linkType = LinkType.OneToOne)
public Client client;
@DataField(name = "ISIN", pos = 4, formatType = "java.lang.String")
public String ISIN_Code;
@DataField(name = "Name", pos = 5, formatType = "java.lang.String")
public String Instrument_Name;
@DataField(name = "Quantity", pos = 6, formatType = "java.lang.String")
public String Quantity;
@DataField(name = "Cur", pos = 7, formatType = "java.lang.String")
public String Currency;
Remark : It is also possible to link class together (but only One to One
relation is supported) using the annotation @LinkField and makes sense
because I don't want to support nested CSV.
