Abstract
A method for freeing memory in a device with limited memory. A plurality of pen strokes is entered into the device, each of which is associated with one of a plurality of pages. The pen strokes are stored in electronic form in the memory. According to the method, memory is freed by all the pen strokes associated with a specific page being deleted. The specific page is determined on the basis of a time at which a pen stroke associated with the page was recorded by the device. A computer program product comprises a computer program for carrying out the method. A device has a data processing unit and a memory and means for carrying out the method.
Claims20
A method for freeing memory in a device with limited memory, into which device a plurality of pen strokes is entered, each of which pen strokes is associated with one of a plurality of pages and is stored in electronic form in the memory, all the pen strokes associated with a specific page being deleted (78) when space in the memory is to be freed, characterized in that the specific page is determined on the basis of a time at which a pen stroke associated with the page was recorded by the device.
The method as claimed in any one of claims 7-9, characterized in that the step (81) of selecting the specific page comprises selecting (76) from the (continued) (continued claim 10) second data structure the page address that has the oldest time.
The method as claimed in claim 1, characterized in that the specific page is determined (continued) (continued claim 15) by a pen stroke associated with the specific page having been recorded prior to a predetermined time.
The method as claimed in any one of the preceding claims, characterized in that a pen stroke is deleted by a state indicator for the memory space that is to be deleted being changed to indicate that the memory space is available.
A device for electronic recording of pen strokes, each of which is associated with a page, which device comprises a data processing unit (7), that has a memory (4, 5) with limited space for storing the pen strokes in electronic form, the data processing unit (7) being arranged to free space in the memory (5) by deleting from the memory (5) all the pen strokes associated with a specific page, characterized in that the data processing unit (7) is arranged to determine (continued) (continued claim 19) the specific page on the basis of the time at which a pen stroke associated with the page was recorded by the device.
