Hello Raman,
here’s an example :
private Type theType;
private void createType()
{
HelperContext ctx = HelperProvider.getDefaultContext();
// define a new type
DataObject typeDef = ctx.getDataFactory().create( "commonj.sdo", "Type" );
typeDef.set( "uri", "http://namespacei/file"; );
typeDef.set( "name", "FileType" );
// add properties
DataObject propDef;
propDef = typeDef.createDataObject( "property" );
propDef.set( "name", "id" );
propDef.set( "type", ctx.getTypeHelper().getType( "commonj.sdo", "String" )
);
propDef = typeDef.createDataObject( "property" );
propDef.set( "name", "fileName" );
propDef.set( "type", ctx.getTypeHelper().getType( "commonj.sdo", "String" )
);
propDef = typeDef.createDataObject( "property" );
propDef.set( "name", "lastModified" );
propDef.set( "type", ctx.getTypeHelper().getType( "commonj.sdo", "Date" ) );
propDef = typeDef.createDataObject( "property" );
propDef.set( "name", "length" );
propDef.set( "type", ctx.getTypeHelper().getType( "commonj.sdo", "Long" ) );
// define the type
theType = ctx.getTypeHelper().define( typeDef );
}
SDOs can be created just like XSD-based ones, e.g.
private DataObject createDataObject( File file )
{
HelperContext ctx = HelperProvider.getDefaultContext();
DataFactory df = ctx.getDataFactory();
// create object of dynamically defined type
DataObject sdo = df.create( theType );
sdo.setString( "id", file.getPath() );
sdo.setString( "fileName", file.getName() );
sdo.setDate( "lastModified", new Date() );
return sdo;
}

Subject: How to add types in SDO on the fly?
Hi,
I am familiar with XSDHelper.define(XSD) to load types into SDO runtime.
We have a requirement to add types at runtime without XSD file. How to achieve
that? Any idea?
Regards
Raman
