[castor-dev] Static instances for Data Objects

Hi Folks,

i have two classes: Note and NoteType:

<class name="dbo_test.Domain.NoteType" identity="code" access="read-only">
    <map-to table="NoteType" xml="NoteType" />
    <field name="code" type="string">
      <sql name="NoteTypeCode" type="char" />
      <xml name="NoteTypeCode" node="attribute"/>
    </field>
    <field name="name" type="string" required="true">
      <sql name="NoteTypeName" type="varchar" />
      <xml name="NoteTypeName" node="element" />
    </field>
    <field name="desc" type="string">
      <sql name="NoteTypeDesc" type="varchar" />
      <xml name="NoteTypeDesc" node="element" />
    </field>
    <field name="image" type="bytes">
      <sql name="NoteTypeImage" type="varbinary" dirty="ignore" />
    </field>
</class>

<class name="dbo_test.Domain.Note" identity="id" key-generator="IDENTITY">
    <map-to table="Note" xml="Note" />
    <field name="id" type="integer">
      <sql name="NoteID" type="integer" />
      <xml name="NoteID" node="attribute"/>
    </field>
    <field name="text" type="string" required="true">
      <sql name="NoteText" type="varchar" />
      <xml name="NoteText" node="element" />
    </field>
    <field name="stamp" type="date" required="true">
      <sql name="NoteStamp" type="date"/>
      <xml name="NoteStamp" node="element" />
    </field>
    <field name="type" type="dbo_test.Domain.NoteType" required="true">
      <sql name="NoteTypeCode"/>
      <xml name="NoteType" node="element" />
    </field>
</class>

i do store instances of NoteType class in database, but i want to load them once and use them in static manner:

public class NoteType {

private String      _code;
private String      _name;
private String      _desc;
private byte[]      _image;

public static NoteType creationNote = new NoteType("C");

public static NoteType deletionNote = new NoteType("D");

.....

}

is it possible to do with Castor?

Regards, Denis.
