Declaration

C#

public XPCollection(
    PersistentCriteriaEvaluationBehavior criteriaEvaluationBehavior,
    Session session,
    XPClassInfo objType,
    CriteriaOperator condition
)

VB.NET

Public Sub New(
    criteriaEvaluationBehavior As PersistentCriteriaEvaluationBehavior,
    session As Session,
    objType As XPClassInfo,
    condition As CriteriaOperator
)

Parameters

Name	Type	Description
criteriaEvaluationBehavior	PersistentCriteriaEvaluationBehavior	A PersistentCriteriaEvaluationBehavior enumeration value that specifies how the persistent criteria are evaluated.
session	Session	The Session that will be used to load and save persistent objects.
objType	XPClassInfo	The persistent class metadata information of objects to include into the collection.
condition	CriteriaOperator	The CriteriaOperator that specifies the criteria for object selection.

Remarks

Note that when an XPCollection is created using a constructor with the criteriaEvaluationBehavior parameter, the collection is loaded immediately and its XPBaseCollection.LoadingEnabled property is automatically set to false. After that, the collection cannot be reloaded using the XPBaseCollection.Reload method, since object loading is disabled.
