Abstract

A method of controlling objects in an information processing system includes the steps of representing objects by a tree having a hierarchical structure, providing each of the objects with a first operation-target flag which indicates whether a corresponding object is a target of a given operation, and performing the given operation on an object upon receiving of an object handling request for the given operation only if the first operation-target flag of the object indicates that the object is a target of the given operation.

Claims

1. A method of controlling objects in an information processing system, comprising:

representing objects by a tree having a hierarchical structure;

providing each of the objects with a first operation-target flag which indicates whether a corresponding object is a target of a given operation;

setting a second operation-target flag in an object handling request, the second operation-target flag indicating whether a group consisting of some of the objects is a target of the given operation; and

performing the given operation on an object upon receiving the object handling request for the given operation only if the second target flag of the object handling request as well as the first operation-target flag of the object indicates that the object is a target of the given operation.

2. The method as claimed in claim 1, wherein said performing is performed with respect to different objects sequentially such that said performing is performed with respect to a given object only after a reply indicative of a completion of the given operation is obtained from another object on which said performing was performed immediately prior to the given object.

3. The method as claimed in claim 1, wherein said performing is performed with respect to different objects in a parallel fashion.

4. A device for controlling objects, comprising:

a message processing unit which receives an object-handling-request message from a client; and

a tree-control unit which controls the objects in a hierarchical structure, attaches a first operation-target flag to each of the objects in order to indicate whether a corresponding object is a target of a given operation, and sets a second operation-target flag in the object handling request, the second operation-target flag indicating whether a group consisting of some of the objects is a target of the given operation wherein said message processing unit performs the given operation on an object upon receiving the object-handling-request message for the given operation only if the second target flag of the object handling request as well as the first operation-target flag of the object indicates that the object is a target of the given operation.

5. The device as claimed in claim 4, wherein said tree-control unit stores names of upper objects and lower objects in relation to a given object.

6. The device as claimed in claim 4, wherein said message processing unit performs the given operation on a given object only after a reply indicative of a completion of the given operation is obtained from another object on which said message processing unit performed the given operation immediately prior to the given object.

7. The device as claimed in claim 4, further comprising a reply handler unit which receives a reply indicative of a completion of the given operation from a given object on which said message processing unit performed the given operation, and reports a receipt of the reply to said message processing unit, wherein said message processing unit performs the given operation on different objects in a parallel fashion.

8. A memory medium having a program embodied therein for controlling a computer to control objects, said program comprising:

a message processing unit configured to receive an object-handling-request message from a client; and

a tree-control unit which controls the objects in a hierarchical structure, attaches a first operation-target flag to each of the objects in order to indicate whether a corresponding object is a target of a given operation, and sets a second operation-target flag in the object handling request, the second operation-target flag indicating whether a group consisting of some of the objects is a target of the given operation wherein said message processing unit performs the given operation on an object upon receiving the object-handling-request message for the given operation only if the second target flag of the object handling request as well as the first operation-target flag of the object indicates that the object is a target of the given operation.

9. The memory medium as claimed in claim 8, wherein said tree-control unit stores names of upper objects and lower objects in relation to a given object.

10. The memory medium as claimed in claim 8, wherein said message processing unit performs the given operation on a give object only after a reply indicative of a completion of the given operation is obtained from another object on which said message processing unit performed the given operation immediately prior to the given object.

11. The memory medium as claimed in claim 8, wherein said program further comprises a reply handler unit which receives a reply indicative of a completion of the given operation from a given object on which said message processing unit performed the given operation, and reports a receipt of the reply to said message processing unit, wherein said message processing unit performs the given operation on different objects in a parallel fashion.
