class, to be persisted in the
specified object store, based on the class ID.
The created object does not yet exist in an object store. To persist the created object to the object store, you must explicitly call the save method, or commit the object via a batch operation. Both approaches cause a round-trip to the server.

- The ObjectStore
object for the object store in which this class instance is to be located.classId

Link
class from the
specified object store. This method does not verify the existence of
the requested object on the server; it simply returns a local reference without
making a round-trip to the server. The local reference is not affiliated with an
object of this class type until you perform a function on the object (for example,
fetch a property value) that causes a round-trip to the Content Engine server.os
- The object store for this instance.className
- The name of the class.objectId
- The ID (GUID) of this class instance. Specifying an ID for this instance is optional; if one is not specified,
an ID for the new object is automatically generated.public static Link fetchInstance(ObjectStore os, Id objectId, PropertyFilter filter)
Link
class
by the specified object ID from the specified object store.
This method always makes a round-trip to the server. You can optionally
include a filter to control which properties to return with the object.
If you pass in null
for the filter
parameter, this method
returns values for all non-object properties and returns placeholders for all object-valued
properties. For details, see the description of the filter
parameter.os
- The ObjectStore
object in which this class instance is located.objectId
- The ID (GUID) of the class instance to retrieve.filter
- A PropertyFilter
object that represents information for
controlling which property values (and with what level of detail and recursion) to return.
If null
, this method returns values for all non-object properties and returns
placeholders for all object-valued properties (PropertyEngineObject
properties with a state of PropertyState.UNEVALUATED
or
PropertyState.REFERENCE
); any subsequent attempts to access an object-valued
property will cause an automatic round-trip to the server to fetch its value.© Copyright IBM Corporation 2006, 2015. All rights reserved.
