OBS provides the following storage classes: Standard, Infrequent Access, Archive, and Deep Archive (under limited beta testing). For the billing about different storage c
As with instance methods and variables, an inner class is associated with an instance of its enclosing class and has direct access to that object's methods and fields. Also, because an inner class is associated with an instance, it cannot define any static members itself. Objects that are in...
A compile-time error occurs if a sealed class is specified as the base class of another class. A sealed class cannot also be an abstract class. Note: The sealed modifier is primarily used to prevent unintended derivation, but it also enables certain run-time optimizations. In particular, ...
Existing searches and criteria are not deleted or modified if a class is disabled; existing objects of disabled object types remain in the Agile PLM database. Note: Item, Change, User, and File Folder base classes cannot be disabled, nor can their child classes or ready-to-use subclasses....
The members of a union (declared with the keywordunion) are public by default. A union cannot be used as a base class in derivation. Once you create a class type, you can declare one or more objects of that class type. For example: ...
This class cannot be inherited. Constructors Expand table EntityCollection<TEntity>() Initializes a new instance of theEntityCollection<TEntity>class. Properties Expand table Count Gets the number of objects that are contained in the collection. ...
The[ref]type accelerator is shorthand for thePSReferenceclass. Using[ref]to type-cast a class member fails silently. APIs that use[ref]parameters can't be used with class members. ThePSReferenceclass was designed to support COM objects. COM objects have cases where you need to pass a value...
