XPO Templates
- 3 minutes to read
This topic describes templates you can use when you implement business classes in eXpress Persistent Objects (XPO).
Member Declaration
XPO Persistent Class
Template: xc
public class PersistentClass : XPObject {
public PersistentClass(Session session) : base(session) { }
}
XPO Persistent Property
Template: xp[1]
string propertyName;
[Size(SizeAttribute.DefaultStringMappingFieldSize)]
public string PropertyName {
get => propertyName;
set => SetPropertyValue(nameof(PropertyName), ref propertyName, value);
}
XPO-Associated Property
Template: xpa
object propertyName;
[Association("object-Programs")]
public object PropertyName {
get => propertyName;
set => SetPropertyValue(nameof(PropertyName), ref propertyName, value);
}
XPO-Associated Collection
Template: xpcl
[Association("Program-Relations")]
public XPCollection<RelationType> Relations {
get {
return GetCollection<RelationType>(nameof(Relations));
}
}
XPO Read-Only Persistent Property
Template: xr[2]
[Persistent(nameof(PropertyName))]
int propertyName;
[PersistentAlias(nameof(propertyName))]
public int PropertyName {
get { return propertyName; }
}
XPO Types
CodeRush includes XPO type mnemonics you can use in member declaration templates.
Type | Mnemonic |
---|---|
DevExpress.Data.Filtering.AggregateOperand | xao |
DevExpress.Data.Filtering.BetweenOperator | xbwo |
DevExpress.Data.Filtering.BinaryOperator | xbo |
DevExpress.Data.Filtering.FunctionOperator | xfo |
DevExpress.Data.Filtering.GroupOperator | xgo |
DevExpress.Data.Filtering.InOperator | xio |
DevExpress.Data.Filtering.UnaryOperator | xuo |
DevExpress.Xpo.Session | xss |
DevExpress.Xpo.UnitOfWork | xu |
DevExpress.Xpo.XPCollection | xcl |
For instance, you can use the p template with the xss mnemonic (the pxss template) to declare a DevExpress.Xpo.Session type property.
DevExpress.Xpo.Session propertyName;
public DevExpress.Xpo.Session PropertyName {
get { return propertyName; }
set {
propertyName = value;
}
}
Note
Visual Studio IntelliSense has priority over CodeRush templates. For information on how to prioritize CodeRush template over Visual Studio IntelliSense, refer to the following topic section: Expand a Template Instead of Visual Studio IntelliSense.
