Abstract

Claims (40)

1. A report layout reference system for processing report layout references in a report, the report layout reference system comprising:

a report object model builder for generating a report object model of a report specification;

a destination repository for storing a location of referenced report components,

a report fetcher for obtaining a report specification having a referenced report component; and

a specification repository for storing report specifications having referenced report components,

wherein the report layout reference system receives a current report specification from the specification repository, the current report specification comprising at least one component reference that references at least one report component of at least one external report specification, obtains the at least one referenced report component of the at least one external report specification, and adds the at least one referenced report component to the current report specification to form a complete report specification.

2. The system as claimed in claim 1 , wherein the report layout reference system determines that the report component associated with the layout component reference is not stored locally.

3. The system of claim 2 , wherein responsive to a determination that the layout component is not stored locally, the report layout reference system opens a remote connection, obtains the external report specification via the remote connection, and locates the report component in the external report specification.

4. The system of claim 1 , wherein responsive to detecting a circular dependency in the report component associated with the layout component reference, the report layout reference system interrupts report processing.

5. The system of claim 1 , wherein responsive to detecting a circular dependency in the report component associated with the layout component reference, the report layout reference system presents an error message to the report object model builder.

6. A method, in a report layout reference system, for processing the layout of component references in a report, the method comprising:

receiving, by a report object model builder of the report layout reference system, a current report specification from a specification repository of the report layout reference system;

detecting, by the report object model builder, a layout component reference in the current report specification, wherein the layout component reference references a report component of an external report specification;

fetching, by a report fetcher of the report layout reference system, the report component associated with the layout component reference; and

adding the report component associated with the layout component reference to the current report specification to form a complete report specification.

7. The method of claim 6 , further comprising:

determining that the report component associated with the layout component reference is not stored locally.

8. The method of claim 7 , wherein responsive to a determination that the layout component is not stored locally, the method further comprises:

opening a remote connection;

obtaining the external report specification via the remote connection; and

locating the report component in the external report specification.

9. The method of claim 6 , further comprising:

responsive to detecting a circular dependency in the report component associated with the layout component reference, interrupting report processing.

10. The method of claim 6 , further comprising:

responsive to detecting a circular dependency in the report component associated with the layout component reference, presenting an error message to the report object model builder.

11. A memory containing computer executable instructions that can be read and executed by a computer for carrying out a method of processing the layout of component references in a report, the method comprising:

receiving, by a report object model builder of the report layout reference system, a current report specification from a specification repository of the report layout reference system;

detecting, by the report object model builder, a layout component reference in the current report specification, wherein the layout component reference references a report component of an external report specification;

fetching, by a report fetcher of the report layout reference system, the report component associated with the layout component reference; and

adding the report component associated with the layout component reference to the current report specification to form a complete report specification.

12. The memory of claim 11 , wherein the method further comprises:

determining that the report component associated with the layout component reference is not stored locally.

13. The memory of claim 12 , wherein responsive to a determination that the layout component is not stored locally, the method further comprises:

opening a remote connection;

obtaining the external report specification via the remote connection; and

locating the report component in the external report specification.

14. The memory of claim 11 , wherein the method further comprises:

responsive to detecting a circular dependency in the report component associated with the layout component reference, interrupting report processing.

15. The memory of claim 11 , wherein the method further comprises:

responsive to detecting a circular dependency in the report component associated with the layout component reference, presenting an error message to the report object model builder.
