Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flowchart of a page insertion method according to an embodiment of the present invention. The page insertion method can be applied to electronic equipment.
As shown in fig. 1, the page insertion method of this embodiment may include:
Optionally, each page has a corresponding object tree according to the content of the page, so that the root node object can be obtained from the object tree corresponding to the page to be inserted, and all child node objects corresponding to the root node are analyzed. The child node object may represent an element to be inserted into the page, such as a picture, a text, and the like.
In an example, when there are a plurality of pages to be inserted, before step 101, the page insertion method provided in this embodiment may further include: and sequencing the pages to be inserted according to rules set by the user.
For example, when there are multiple pages to be inserted, thumbnails of the pages to be inserted, or page numbers or names may be displayed, so that the user may sort the pages as required, and then step 101 is sequentially performed on the multiple pages to be inserted according to the sort of the user.
Specifically, when a user edits a page, different types of elements may be added to the page, so that the type of the child node object corresponding to each element can be determined before insertion, so that different insertion modes are used for different types of child node objects, and the insertion speed of the page is increased.
It is understood that step 103 is only performed if the child node object whose type is a non-reference object is not included in the child node object.
In one example, each child node object corresponds to an ID, and the cache container also stores the ID of the reference object, so step 103 may include: and determining whether the child node object with the type as the reference object in the plurality of child node objects exists in the cache container according to the ID of the child node object with the type as the reference object in the plurality of child node objects.
It can be understood that, in the embodiment of the present invention, a child node object of which a type is a reference object and exists in the cache is made to be a first child node object, a child node object of which a type is a reference object and does not exist in the cache is made to be a second child node object, and a child node object of which a type is a non-reference object is made to be a third child node object.
Thereafter, step 104 is performed for the first child node object. For the second child object, step 105 is performed.
And 104, referring the first child node object which is of the reference object type and exists in the cache to the target page from the cache container aiming at the first child node object in the plurality of child node objects so as to generate a new page.
Optionally, if the child node object is a reference object and is cached in the cache container, the child node object may be directly referenced from the cache container to the target page, that is, the ID corresponding to the child node object is referenced to the target page, so as to generate the new page. Therefore, the memory consumption can be effectively reduced, and the disk space occupied by the final file can be greatly reduced because the child node object does not need to be copied to the target page.
And step 105, copying a second child node object which is of the type of the reference object and does not exist in the cache in the plurality of child node objects.
In an example, after step 105, the page inserting method provided in this embodiment may further include: and adding a second child node object which is not in the cache container to the cache container so that when a page references the same reference object, the reference can be directly performed, thereby improving the speed, reducing the memory consumption and reducing the occupied space.
And 106, adding the copied second child node object into the superior parent object, and generating a new page object tree after traversing a plurality of child node objects.
Optionally, because a reference object that is not in the cache container cannot be added to the target page by reference, a copy needs to be made and added to the parent object at the upper level to generate a new page object tree.
And step 107, inserting the new page object tree into the array corresponding to the target page to generate a new page.
And step 109, adding the copied third child node object into the superior parent object, and generating a new page object tree after traversing a plurality of child node objects.
It will be appreciated that the plurality of child nodes may include a second child node object and a third child node object. Then, the copied second child node object and the copied third child node object may be added to the parent object at the upper level, after traversing multiple child node objects, a new page object tree is generated, and then the new page object tree is inserted into the array corresponding to the target page to generate a new page.
By using the page inserting method provided by the embodiment of the invention, the object which is already quoted in the cache container in the page to be inserted is inserted into the target page in a quoting mode, so that the page inserting speed can be effectively improved, the memory consumption can be reduced, and the disk space occupied by the final file can be reduced.
