Specific implementation mode
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
The problem of present invention cannot generate the whole catalogue of system for existing Piece file mergence, provides a kind of Piece file mergence
Method and device is realized and waits for packaging file according to what user selected, a file destination with full directory is generated, to convenient
The purpose of access.
As shown in Fig. 2, a kind of Piece file mergence method of the embodiment of the present invention, includes the following steps：
Step 11, after detecting the file to be combined that user has selected, the directory entry letter of the file to be combined is extracted
Breath generates original directory；
Step 12, user is obtained to the operation information of the operation of the original directory/not, updates directory entry information, it is raw
At target directory；
Step 13, the file data of the target directory is merged, generates file destination.
Wherein, the directory entry information includes：Directory entry ID, directory entry title, father ID, brother ID.
In the Piece file mergence method of the embodiment of the present invention, user need to only choose file to be combined, and in generation
Original directory retains full content or the chapters and sections content retained is wanted in selection, goes to arrange out new catalogue according to the needs of oneself
Sequentially, this method will generate target directory according to the user's choice and finally obtain file destination, which has a pair
The complete catalogue of system of answering property is more convenient the access of user.
In the following, wanting to incite somebody to action with user《Highly skilled doctor Liuxia favour one》《Highly skilled doctor Liuxia favour two》《Highly skilled doctor Liuxia favour three》《First military god》
With《Nature's mystery》In section be merged into for a file, then according to the Piece file mergence method of the embodiment of the present invention, just
It needs：
These files to be combined are extracted after detecting the file to be combined that user has selected according to step 11 first
Directory entry ID, directory entry title, father ID, brother ID, generate original directory.This original directory is as shown in figure 3, wherein band saves
The chapters and sections of contracted notation indicate multiple chapters and sections in original.Certainly this original directory is first only shown, user could be facilitated to complete
Customized selection.It should be noted that directory entry ID is the ID number for the representative own identification that each directory entry carries；Father ID
Refer to the directory entry ID of the upper level directory entry of the directory entry, when the directory entry is first class catalogue item, father ID is 0；Brother
ID refers to the directory entry ID of the directory entry at the same level of the catalogue, when the directory entry is first first class catalogue imported, brother
ID is 0.The logical relation between directory entry can be well understood by father ID and brother ID.
It should be understood that the demand due to user is different, have it is desired be exactly by all Piece file mergences to be combined
For the file of an entirety, some is then the partial content needed in file to be combined, therefore step 12 includes：
Step 121, operation information of the user to the original directory is obtained, directory entry information is updated, generates target
Catalogue；Or
Step 122, not operation information of the user to the original directory is obtained, it is directly raw according to original directory entry information
At target directory.
In this way, if user wants to read《Highly skilled doctor Liuxia favour one》《Highly skilled doctor Liuxia favour two》《Highly skilled doctor Liuxia favour three》《First is military
God》With《Nature's mystery》In full content, do not make other modifications yet, user can be obtained according to step 122 to the original directory
Not operation information directly generates target directory according to original directory entry information（Including whole chapters and sections catalogues）, but often,
People can adjust catalogue according to the reading habit of oneself, then obtaining operation of the user to the original directory according to step 121
Information updates directory entry information, generates target directory
Step 121 is the step of generating new target directory after user is according to oneself needing to adjust original directory.That
For the different adjustment operations of user, specific steps are again different.Sometimes some otiose mesh are had in original directory
Record item is added, so the operation that user often has is to delete extra unwanted directory entry, at this moment, as shown in figure 4,
Step 121 includes：
Step 1211, in the delete operation for detecting user, the directory entry chosen is deleted；
Step 1212, judge whether the item that deltrees has subdirectory item, if there is subdirectory item, by the item that deltrees
The father ID of all subdirectory items be revised as the father ID of the item that deltrees；
Step 1213, it deltrees next directory entry of item described in judgement and whether the item that deltrees is to close side by side
A brother of next directory entry of the item that deltrees ID is then revised as the item that deltrees by system if coordination
Brother ID.
It, will be by the chapters and sections catalogue entry deletion, then such as when detecting that user deletes the operation of " nature's mystery chapter 1 "
Judge whether the directory entry has subdirectory item, know as shown in Figure 3 the chapters and sections be no subdirectory item need not just carry out it is next
Step, if the chapters and sections are Section 1.1 there are subdirectory item hypothesis, then just needing Section 1.1 of parent directory item ID（Chapter 1
Directory entry ID）It is revised as the parent directory item ID of chapter 1.Finally also to judge the next directory entry and the catalogue of the directory entry
The relationship of item, next directory entry is " nature's mystery chapter 2 " and the directory entry is coordination, so just needing to change " nature's mystery second
The brother ID of chapter " is revised as the brother ID of the directory entry.Bibliographic structure as shown in Figure 5 is obtained after deleting extra directory entry, this
One operation purpose is in order to facilitate follow-up adjustment bibliographic structure, if certain user wants reservation all the elements and can not also carry out
This operation.
Step 1211, step 1212, step 1213 not only realizes the purpose for deleting the deletion item that user chooses, but also will
The information of other directory entries associated with item is deleted is modified, and ensure that the orderliness of the logical relation of whole catalogue is clear.
Sometimes, directory entry name modifications can be the content oneself being more familiar in order to which later stage lookup facilitates by user, work as user
Operation be change directory entry title when, step 121 further includes：
Step 1214, when detecting that user edits the operation of directory entry title, judge whether new directory item title is sky,
It is new directory item title by former directory entry name modifications if new directory item title is not sky；If the entitled sky of new directory item,
Retain former directory entry title.
Certainly, more often, user can also adjust to the sequence of positions of directory entry, at this point, as shown in fig. 6, step
Rapid 121 further include：
Step 1215, when detecting that user adjusts the operation of directory entry position, judge the parent directory item for adjusting directory entry
Whether change, if the variation of parent directory item and presence, new father ID is revised as to the directory entry ID of current parent directory item；If
Parent directory item changes but is not present, then new father ID is set as 0；
Step 1216, judge whether the brother's directory entry for adjusting catalogue changes, it, will if the variation of brother's directory entry and presence
New brother ID is revised as the directory entry ID of current brother's directory entry；If brother's directory entry changes but is not present, new brother ID is arranged
It is 0.
For example, as shown in fig. 7, by " highly skilled doctor's Liuxia's favour（Two）Chapter 1 " it is put into " highly skilled doctor's Liuxia's favour（One）Chapter 1 "
In subdirectory, user's adjustment " highly skilled doctor's Liuxia's favour is being detected（Two）When this operation of position chapter 1 ", the mesh will be judged
Whether the parent directory item of record item changes, and finds the parent directory item variation of the directory entry at this time and exists, is " highly skilled doctor's Liuxia's favour
（One）Chapter 1 ", then by highly skilled doctor's Liuxia's favour（Two）Chapter 1 " new father ID is revised as " highly skilled doctor's Liuxia's favour（One）Chapter 1 "
Directory entry ID, parent directory item changes but is not present sometimes certainly, then new father ID is set as 0.The directory entry is judged again
Brother's directory entry whether change, at this point, the variation of brother's directory entry but being not present, then new brother ID is set as 0, if brother's catalogue
New brother ID is then revised as the directory entry ID of current brother's directory entry by item variation and presence.
Likewise, step 1215, step 1216 by other and adjusts location entries while adjusting directory entry position
The information of associated directory entry is modified, and ensure that the orderliness of the logical relation of whole catalogue is clear.
In this way, just having obtained user-defined target directory, the demand that can be directed to individual subscriber goes to adjust, and has more
Specific aim and applicability.
Finally, according to step 13, the file data of the target directory is merged, generates file destination.User is most
What is obtained eventually is exactly the file destination.In embodiments of the present invention, destination file format physical container is as shown in figure 9, include
File header information：Vessel head, the information such as description copyright, version, old version quantity；File data area：Container contents, each file
The information such as format, version, file size；File directory information area：（Newly-generated）Each file in file directory information, file
Map information.Wherein file directory information area and file data area are likely to occur multiple in a vessel, are formed one group and are gone through
The Piece file mergence of history records.Such as file header description information list structure is as shown in table 1（Wherein packet is above-mentioned file destination
Similarly hereinafter）：
1 file header description information list structure explanation of table
It should be understood that encryption and copyright protection can be added in extending information.
And file directory information plot structure is as shown in table 2：
2 file directory information plot structure explanation of table
It should be appreciated that：
（1）Directory entry can be the non-directory entry selected in e-book, that is, support virtual directory item（Corresponding catalogue source length
It is 0）, whole catalogue is completed to facilitate；
（2）Same directory information area directory entry be it is unique, that is, be not present same directory area there are two or more catalogue
ID is identical, reports an error when present；
（3）Same directory entry is subject to and is finally occurred when multiple directory areas occur, but directory entry operation is locking
When, ignore subsequent same directory entry；
（4）It is 0 to allow directory information length, indicates that this packet without catalogue, occurs with electronic book documentary in File Mapping table
Sequentially, it is that fraternal catalogue at the same level shows by each e-book root.
Illustrated according to the structure of table 1 and table 2, as shown in figure 9, step 13 specifically includes：
Step 131, file destination header is generated, the header includes：Directory information area quantity and directory information area
Offset；
Step 132, judge whether each file needs to compress according to target directory sequence, if desired compress, then root
Compression is carried out according to specified compress mode and active data area tail portion is written into current file stream；If need not compress, directly
By current file stream write-in active data area tail portion；
Step 133, fileinfo is inserted into file information structure；
Step 134, catalogue data area data are generated according to the target directory information, is given birth to according to the file information structure
At File Mapping Data Area data, filling file directory information area；
Step 135, believed according to the directory information area quantity of file directory information area data modification File header information and catalogue
Cease area's offset.
In embodiments of the present invention, the file data of 131-135 completions target directory merges through the above steps, final
To file destination, such as continue above-mentioned example, obtains target mesh file as shown in Figure 10.The file destination includes according to mesh
Heading records tactic each file, has reached User Defined selection, sequence, has realized and wait being packaged according to what user selected
File generates a file destination with full directory, to facilitate the purpose of access.
The file for omitting selection sometimes during Piece file mergence occasionally wants to add new file it is necessary to merge
Increment is changed in good file, and the structure tail portions shown in original Fig. 8 increase new file data area and file directory information area；
Next directory information area offset of the last one original directory information block is directed toward to the starting in this newly-increased directory information area
Position.
