Description

Method and device for analyzing stored files

Technical field

The present invention relates to the field of computer technologies, and in particular, to a method and an apparatus for analyzing a stored file.

Background technique

In the prior art solution, displaying the content of the storage file to the UI of the interactive electronic whiteboard by directly parsing the format of the storage file from the storage format into a data structure format in the memory, that is, a memory model. And the memory model is rendered to achieve. Since the parsing process in the prior art directly parses the format of the file from the storage format to the memory model, whether the storage format of the file changes or the memory model changes, the implementation logic of the parsing process needs to be modified. .

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a schematic flowchart diagram of an embodiment of a method for parsing a storage file provided by the present invention, including steps S11 to S13, as follows:

S11: reading a storage file, where the storage file includes a parsing logical identification code corresponding to a format of the storage file;

S12: Parse the storage file into an intermediate format data structure according to a parsing logic corresponding to the parsing logic identifier, where the intermediate format data structure includes each content in the storage file. The element identification code corresponding to the element;

S13: Convert the intermediate format data structure into a memory storage file according to a conversion logic that is preset in common with the element identifier; wherein the memory storage file is a mapping of the storage file in memory.

It should be noted that the method provided by the present invention mainly consists of a parsing process and a conversion process, that is, when a storage file is parsed and converted into an in-memory storage file, the storage file is first parsed according to corresponding parsing logic. After the intermediate format data structure, the intermediate format data structure is converted into an in-memory storage file according to the corresponding conversion logic. The parsing logic used in the parsing process is determined by the format of the parsed storage file. The transformation logic used in the conversion process is determined by the content elements in the converted intermediate format data structure.

It should be further noted that the format of the storage file may be an xml format, a json format, or an svg format. The intermediate format data structure can be a tree structure or other types of data structures such as linked lists and stacks.

The tree-type intermediate format data structure is taken as an example to illustrate the node reference relationship in the intermediate format data structure. Each node in the intermediate format data structure includes three items of Name, Value and Children, which respectively represent the name of the node, the value of the node, and the child nodes of the node.

When the attribute represented by a node is an underlying data type such as an integer, a decimal, or a string, the Name of the node is the name of the attribute, the Value of the node is the value of the attribute, and the Child value of the node is null. For example, when the attribute is X=100, the intermediate format corresponding to the attribute is shown in Figure 2.

When the attribute represented by a node is a composite data type, that is, the attribute is a composite attribute composed of several single attributes, the Name of the node is the name of the attribute, the value of the node is null, and the child of the node points to A node that represents each single attribute. For example, when the attribute is the coordinate point Point (100, 200), the attribute consists of a single attribute cx=100 and a single attribute cy=200, so the intermediate format corresponding to the attribute is as shown in FIG.

When the attribute represented by a node may be the underlying data type or the composite data type, the Name of the node is the name of the attribute, the value of the node is null, and the Child of the node points to the specific The node of the data type and content. For example, when the property is Background Background, the type of the property may be a color or an image. When the type of the attribute is a color, the intermediate format corresponding to the attribute is as shown in FIG. 4 .

When the type of the attribute is a picture, the intermediate format corresponding to the attribute is as shown in FIG. 5.

When the attribute represented by a node is an array type, the Name of the node is the name of the attribute, the value of the node is null, and the Children of the node points to the node representing the attributes of each array element in the attribute. For example, when the attribute is an array of Points consisting of two coordinate points Point, the intermediate format corresponding to the attribute is as shown in FIG. 6.

In a preferred embodiment, when a certain storage file needs to be parsed and converted into an in-memory storage file, the computer reads the storage file and according to the parsing logic corresponding to the version number of the parsing logic in the storage file, that is, The parsing logic corresponding to the logical identifier is parsed, and the storage file is parsed into an intermediate format data structure. Subsequently, the computer traverses the intermediate format data structure and converts the intermediate format data structure into an in-memory storage file according to conversion logic that corresponds to the element identification code of each content element therein. The memory storage file is a mapping of the storage file in memory. The intermediate format data structure may be a tree structure, or may be another type of data structure such as a linked list or a stack. When the middle When the data structure is a tree structure, after the storage file is parsed, each content element is respectively parsed into each subtree having a common parent node in the tree structure, and the root nodes of each subtree respectively correspond to The element identifier of the content element, and each child node in each subtree is the attribute of its parent node.

For example, suppose a storage file in an xml format is as follows:

This includes the content element <iwb:shape> and the content element <iwb:magnifier>, which represent an ellipse and a magnifying glass, respectively. When the storage file needs to be parsed and converted into an in-memory storage file, the computer reads the storage file, and obtains a corresponding parsing logic capable of parsing the file in the xml format according to the parsing logical identifier in the storage file, and according to the The parsing logic parses the storage file into an intermediate format data structure of the tree type as shown in FIG.

The content element <iwb:shape> and the content element <iwb:magnifier> respectively correspond to two subtrees whose common parent node is an elements node. The node name in the root node of the subtree corresponding to the content element <iwb:shape> is the element identifier of the content element <iwb:shape>, that is, the iwb:shape, and the attribute of the content element <iwb:shape> is parsed as the The child or grandchild of the root node. The node name in the root node of the subtree corresponding to the content element <iwb:magnifier> is the element identifier of the content element <iwb:magnifier>, ie, iwb:magnifier, and the attribute of the content element <iwb:magnifier> is parsed as The child or grandchild of the root node.

When the intermediate format data structure is converted into an in-memory storage file, the computer traverses the intermediate format data structure, and obtains a common corresponding conversion logic according to all of the element identification codes, iwb:shape and iwb:magnifier, and the conversion logic is The subtree corresponding to the content element <iwb:shape> can be converted, and the subtree corresponding to the content element <iwb:magnifier> can be converted. According to the conversion logic, the intermediate format data structure is converted into a corresponding memory storage file, which includes a shape content element and its corresponding attribute, and a magnifier content element and its corresponding attribute.

It can be seen that the intermediate format data is parsed into an intermediate format data structure according to parsing logic corresponding to the format of the stored file, and the conversion format logic corresponding to the content element in the intermediate format data structure The structure is converted into a memory storage file, so that the format change of the storage file is isolated from the change of the content of the storage file, that is, the parsing process can parse the storage file of a plurality of different formats, regardless of what is included in the storage file. The content element can convert a plurality of intermediate format data structures containing different content elements during the conversion process, regardless of the format of the corresponding storage file. Therefore, the parsing method of the storage file provided by the embodiment of the present invention can improve the compatibility of the device with the file format. At the same time, since only the new parsing logic needs to be added when the format of the storage file changes, when the content element of the storage file changes, only the new conversion logic is added, and the storage file with the new format or the new content element can be added. Parsed and converted to the corresponding memory storage file, so the process of file format compatibility is easy and simple.

It should be noted that the parsing logic is stored and managed by the parsing manager, and each parsing logic in the parsing manager has a unique version number, that is, parsing the logical identifier. Whenever you add a new storage file format, you need to add the corresponding parsing logic in the parsing manager. When the storage file needs to be parsed into the intermediate format data structure, the computer finds the parsing logic corresponding to the parsing logical identifier in the storage file in the parsing manager and acquires the parsing logic, and parses the stored file according to the parsing logic. Is an intermediate format data structure.

For example, as shown in FIG. 8, the flow chart of the analysis process of the present embodiment is shown, and the analysis manager 81 stores the analysis logic A and the analysis logic B. When it is necessary to parse the storage file A of the format A into the intermediate format data structure 82, the parsing logic A is obtained from the parsing manager 81, and the storage file A is parsed according to the parsing logic A. When it is necessary to parse the storage file B of the format B into the intermediate format data structure 82, the parsing logic B is obtained from the parsing manager 81, and the storage file B is parsed according to the parsing logic B. When a storage file C of the format C is newly added to the storage file, the analysis logic C capable of parsing the storage file C is added to the analysis manager 81.

Determining, according to the first parsing logic, a format parser corresponding to a format of the storage file, the storing The file is parsed into a corresponding format data structure;

It should be noted that the parsing logic is divided into two parts, namely, a first parsing logic and a second parsing logic. The first parsing logic corresponds to the format of the storage file, and is used to call a format parser corresponding to the format of the stored file, thereby parsing the storage file into a corresponding format data structure. The second parsing logic is configured to recurse the format data structure, thereby traversing the format data structure and modifying the node reference relationship therein, and further parsing the format data structure into an intermediate format data structure. The format data structure may be a tree structure, or may be another type of data structure such as a linked list or a stack. The node reference relationships of the format data structures corresponding to the format of different storage files may be the same or different.

For example, when parsing a storage file of an xml format into an intermediate format data structure, first calling an xml format parser according to the first parsing logic in the parsing logic, and parsing the storage file into an xml format data structure, that is, an xml tree. . Then, according to the second parsing logic in the parsing logic, the xml format data structure is recursively, thereby traversing the xml format data structure and modifying the node reference relationship therein, and further parsing the xml format data structure into the intermediate format data structure.

In another preferred embodiment, the converting the intermediate format data structure into an in-memory storage file according to the conversion logic that is commonly associated with the element identification code, which includes:

It should be noted that the conversion logic is stored and managed by the conversion manager, and each conversion logic in the conversion manager has an element identifier of all content elements that it can convert. Whenever a content element in a storage file changes to implement a new function, the corresponding conversion logic needs to be added in the conversion manager in advance. When the intermediate format data structure needs to be converted into the memory storage file, the conversion logic corresponding to the element identifier of each content element in the intermediate format data structure is found in the conversion manager and the conversion logic is obtained, and according to The conversion logic recursively transforms the intermediate format data structure to convert the intermediate format data structure into an in-memory storage file.

For example, as shown in the flow chart of the conversion process of the present embodiment as shown in FIG. 9, the conversion manager 92 stores conversion logic A and conversion logic B. Assuming that the conversion logic A can convert an intermediate format data structure including the content element a and the content element b, the conversion logic B can convert an intermediate format data structure including the content element a, the content element b, and the content element c. When the content element a and the content element b are included in the intermediate format data structure 91, the slave conversion manager 92 The conversion logic A is obtained, and the intermediate format data structure 91 is converted into a corresponding memory storage file A according to the conversion logic A, and the converted memory storage file A includes the content element a and its corresponding attribute, and the content element b. And its corresponding properties. When it is necessary to add a content element d in a storage file including the content element a and the content element b to implement a new function, adding in the conversion manager 92 is capable of converting the middle including the content element a, the content element b, and the content element d The conversion logic C of the format data structure.

It should be noted that after the storage file is parsed and converted into an in-memory storage file, the content elements in the memory storage file are rendered to be displayed in the display screen.

For example, if a storage file includes a content element a representing an ellipse and a content element b representing a magnifying glass, the corresponding memory storage file includes the content element a and its corresponding attribute, and the content element b and its corresponding Attributes. After rendering the memory storage file, an ellipse and a magnifying glass are displayed on the display of the device.

The method for parsing a storage file according to an embodiment of the present invention, parses a storage file into an intermediate format data structure according to parsing logic corresponding to a format of the storage file, and according to a content element corresponding to the intermediate format data structure The conversion logic converts the intermediate format data structure into an in-memory storage file, so that the format change of the storage file is isolated from the change of the content of the storage file, that is, the parsing process can parse the storage file of a plurality of different formats, and Regardless of what content elements are included in the storage file, a plurality of intermediate format data structures containing different content elements can be converted during the conversion process regardless of the format of the corresponding storage file. Therefore, the parsing method of the storage file provided by the embodiment of the present invention can improve the compatibility of the device with the file format. At the same time, since only new parsing logic needs to be added when the format of the storage file changes, when the content element of the storage file changes, only new conversion logic needs to be added, so the process of implementing format compatibility is easy and simple.

Correspondingly, the present invention also provides a device for analyzing a file, which can implement all the processes of the method for parsing a file in the above embodiment.
