Abstract

In one embodiment, a computing device receives a request for content for a content layout in a displayable region of a screen associated with the system. The device determines, based on application-tailored recycling policies, whether a recycler includes a display object that is suitable for recycling or re-use. If it does not, the device creates the display object and fills it with the content. If it does, and if the display object contains the content, the device updates elements of the display object as needed; otherwise, if the display object does not contain the content, the device fills the display object with the content and returns it. Embodiments described herein may also be performed with sub-elements of a display object, some of which may comprise nested display objects.

Claims

1. A method comprising:

by a computing device, receiving a request for particular content for a content layout in a displayable region of a screen associated with the computing device;

by the computing device, determining, based on application-tailored recycling policies, whether a recycler includes a display object that is suitable for recycling or re-use, the display object containing the particular content;

if the recycler does not include the display object that is suitable for recycling or re-use;

by the computing device, creating the display object; and

by the computing device, filling the display object with the particular content;

if the recycler does include a display object that is suitable for recycling or re-use;

by the computing device, determining whether the display object contains the particular content;

if the display object contains the particular content;

by the computing device, updating elements of the display object as needed;

if the display object does not contain the particular content;

by the computing device, filling the display object with the particular content;

by the computing device, returning the display object.

2. The method of claim 1, further comprising:

receiving an indication that the display object is no longer needed for the content layout in the displayable region; and

storing the display object in the recycler.

3. The method of claim 2, further comprising:

encapsulating the display object in a wrapper object before the returning the display object, wherein the returning the display object comprises returning the encapsulated display object; and

upon receiving the indication that the display object is no longer needed by the computing device, extracting the display object from the wrapper object before storing the display object in the recycler.

4. The method of claim 3, wherein, after the display object is extracted, the wrapper object is recycled by a recycling utility managed by an operating system.

5. The method of claim 1, wherein the application-tailored recycling policies comprise application-specific, device-specific, or user-specific recycling policies.

6. The method of claim 1, wherein the display object is stored in the recycler in association with a retrieval key comprising:

a position of the particular content in the content layout, a content identifier, a hash key generated based on the particular content, or a timestamp of an activity related to the particular content.

7. The method of claim 1, wherein the particular content comprises social-networking information, and wherein the display object is stored in the recycler in association with retrieval key comprising an identifier associated with one or more elements in a social graph to which the particular content is related.

8. One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

receive a request for particular content for a content layout in a displayable region of a screen;

determine, based on application-tailored recycling policies, whether a recycler includes a display object that is suitable for recycling or re-use, the display object containing the particular content;

if the recycler does not include the display object that is suitable for recycling or re-use;

create the display object; and

fill the display object with the particular content;

if the recycler does include a display object that is suitable for recycling or re-use;

determine whether the display object contains the particular content; and

if the display object contains the particular content;

update elements of the display object as needed;

if the display object does not contain the particular content;

fill the display object with the particular content; and

return the display object.

9. The media of claim 8, wherein the software is further operable when executed to:

receive an indication that the display object is no longer needed for the content layout in the displayable region; and

store the display object in the recycler.

10. The media of claim 9, wherein the software is further operable when executed to:

encapsulate the display object in a wrapper object before the returning the display object, wherein the returned display object comprises the encapsulated display object; and

upon receiving the indication that the display object is no longer needed, extract the display object from the wrapper object before storing the display object in the recycler.

11. The media of claim 10, wherein, after the display object is extracted, the wrapper object is recycled by a recycling utility managed by an operating system.

12. The media of claim 8, wherein the application-tailored recycling policies comprise application-specific, device-specific, or user-specific recycling policies.

13. The media of claim 8, wherein the display object is stored in the recycler in association with a retrieval key comprising:

a position of the particular content in the content layout, a content identifier, a hash key generated based on the particular content, or a timestamp of an activity related to the particular content.

14. The media of claim 8, wherein the particular content comprises social-networking information, and wherein the display object is stored in the recycler in association with retrieval key comprising an identifier associated with one or more elements in a social graph to which the particular content is related.

15. A system comprising:

one or more processors; and

a memory coupled to the processors comprising instructions executable by the processors, the processors being operable when executing the instructions to;

receive a request for particular content for a content layout in a displayable region of a screen associated with the system;

determine, based on application-tailored recycling policies, whether a recycler includes a display object that is suitable for recycling or re-use, the display object containing the particular content;

if the recycler does not include the display object that is suitable for recycling or re-use;

create the display object; and

fill the display object with the particular content;

if the recycler does include a display object that is suitable for recycling or re-use;

determine whether the display object contains the particular content; and

if the display object contains the particular content;

update elements of the display object as needed;

if the display object does not contain the particular content;

fill the display object with the particular content; and

return the display object.

16. The system of claim 15, wherein the processors are further operable when executing the instructions to:

receive an indication that the display object is no longer needed for the content layout in the displayable region; and

store the display object in the recycler.

17. The system of claim 16, wherein the processors are further operable when executing the instructions to:

encapsulate the display object in a wrapper object before the returning the display object, wherein the returned display object comprises the encapsulated display object; and

upon receiving the indication that the display object is no longer needed, extract the display object from the wrapper object before storing the display object in the recycler.

18. The system of claim 17, wherein, after the display object is extracted, the wrapper object is recycled by a recycling utility managed by an operating system.

19. The system of claim 15, wherein the application-tailored recycling policies comprise application-specific, device-specific, or user-specific recycling policies.

20. The system of claim 15, wherein the display object is stored in the recycler in association with a retrieval key comprising:

a position of the particular content in the content layout, a content identifier, a hash key generated based on the particular content, or a timestamp of an activity related to the particular content.
