Hello Keith,
Thanks for your inputs, I am making progress and want to improve further the
way I am mapping my objects. The classes basically I have are like this:
Public class TcmMdlListeEntites{
ArrayList _list;
ArrayList _listeComptes;
ArrayList _listePersonnes;
}
Public abstract class TcmModel{
}
Public class TcmMdlCompte extends TcmModel{
}
Public class TcmMdlPersonne extends TcmModel{
}
The application adds a TcmModel to the _list and it could either be
TcmMdlCompte or TcmMdlPersonne or any other
Derived class.
I want to get rid of these 2 list variables just to handle sub-classes. The
mapping I have currently is this:
<?xml version="1.0"?>
<mapping>
<class name="tcm.mdl.TcmMdlListeEntites" auto-complete="false">
<map-to xml="TCM"/>
<field name="_listeComptes" type="tcm.mdl.TcmMdlCompte"
collection="arraylist" get-method="getComptes" set-method="setListeComptes">
<bind-xml name="Compte" node="element"/>
</field>
<field name="_listePersonnes" type="tcm.mdl.TcmMdlPersonne"
collection="arraylist" get-method="getPersonnes" set-method="setListePersonnes">
<bind-xml name="Personne" node="element"/>
</field>
</class>
<class name="tcm.mdl.TcmMdlCompte" auto-complete="false">
<map-to xml="Compte"/>
<field name="_refPersonne" type="string" get-method="getRefPersonne"
set-method="setRefPersonne">
<bind-xml name="ReferencePersonne" node="element"/>
</field>
<field name="_typeImpot" type="string" get-method="getTypeImpot"
set-method="setTypeImpot">
<bind-xml name="TypeImpot" node="element"/>
</field>
<field name="_anneeFiscale" type="string" get-method="getAnneeFiscale"
set-method="setAnneeFiscale">
<bind-xml name="AnneeFiscale" node="element"/>
</field>
<field name="_numeroOrdre" type="string" get-method="getNumeroOrdre"
set-method="setNumeroOrdre">
<bind-xml name="NumeroOrdre" node="element"/>
</field>
</class>
<class name="tcm.mdl.TcmMdlPersonne" auto-complete="false">
<map-to xml="Personne"/>
<field name="_referencePersonne" type="string"
get-method="getReferencePersonne" set-method="setReferencePersonne">
<bind-xml name="ReferencePersonne" node="element"/>
</field>
</class>
</mapping>
Which gives me this after marshalling:
<?xml version="1.0" encoding="UTF-8"?>
<TCM>
<Compte>
<ReferencePersonne>14602769</ReferencePersonne>
<TypeImpot>90</TypeImpot>
<AnneeFiscale>2002</AnneeFiscale>
<NumeroOrdre>1</NumeroOrdre>
</Compte>
<Personne>
<ReferencePersonne>14602769</ReferencePersonne>
</Personne>
</TCM>
Is there a way that a mapping file could work with just the _list variable
without having to create 2 separate lists for sub-classes ? Is there a mapping
like this somewhere or would really appreciate if you get time to provide a
mapping that can do this...I will implement this if possible across all our
apps...
I am refactoring the application and trying to do things the best way possible.
Would appreciate your inputs.
Thanks a lot
Saurabh

Objet : Re: TR: [castor-user] Problem while unmarshalling
Does your getListeComptes() method return the actual ArrayList or a copy
of it? Unfortunately, Castor will actually attempt to incrementally add
the items to the ArrayList returned from the getter. If it returns a
copy then that explains why the list is empty after unmarshalling. There
are two workarounds:
1. Return the actual list reference instead of a copy
-or-
2. Specify an add method instead of the actual list mutator, for example:
set-method="addListeCompte"
where you have a method defined as such:
public void addListeCompte(Compte compte) {
_myListCompte.add(compte);
}
