Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.
The embodiment of the invention provides a data writing method which is applied to terminal equipment, wherein the terminal equipment is used for acquiring the data type of target data to be written and storing the target data of a preset data type in a persistence container.
The following will take a terminal device as an example, and describe in detail a data writing method provided by the embodiment of the present invention in connection with a specific implementation manner: the method comprises the steps that a terminal device determines a target data type of target data and target identification information of the target data according to a writing instruction aiming at the target data, obtains a writing method name and a reading method name of the target identification information according to the target identification information, obtains a general type writing method and a general type reading method of the target data type according to the target data type, and calls the general data writing method if the terminal device judges that the target data type of the target data is a preset data type, and transmits the target data and the writing method name corresponding to the target identification information into a storage space; if the terminal equipment judges that the target data type of the target data is a non-preset data type, converting the target data type into a preset data type, calling a universal data writing method, and transmitting the writing method name and the target data of the preset data type into a storage space.
A data writing method is that a terminal device transmits a writing method name and target data of a preset data type to a storage space, as shown in figure 1,
step 101: when a write instruction for target data is received, a target data type of the target data and target identification information of the target data are determined.
In the embodiment of the invention, when the terminal equipment receives the writing instruction aiming at the target data, the target identification information and the target data type of the target data can be determined according to the target data, wherein the writing instruction can be generated in response to user operation or can be generated by triggering a system program in the system operation process of the terminal equipment.
For example, when the terminal device receives the write command, the target data of the write command is "YES", and then the terminal device may determine that the target identification information is audioswitch open and the data type is boolean.
Step 102: and judging whether the target data type of the target data is a preset data type or not.
In the embodiment of the present invention, the preset data type is an OC type, and the target data type is an OC type or a non-OC type, so that in order to make the data types of the target data in the incoming persistent container consistent, the terminal device needs to determine whether the target data type of the target data is the preset data type.
Step 103: and if the target data type of the target data is the preset data type, calling a general data writing method, and transmitting the target data and a writing method name corresponding to the target identification information into a storage space.
In the embodiment of the invention, if the target data type of the target data is the preset data type, the terminal equipment does not need to perform type conversion on the target data type any more, the terminal equipment analyzes the write method name into the target identification information through a name conversion method, maps the target identification information into the container write method name, and transmits the container write method name and the target data into the persistent container through a general data write method.
For example, if the target data is YES, the writing method is named as "setaudioswitch open", the target data type is "OC", the terminal device encapsulates "YES" as "oc_yes", the name conversion method parses "setaudioswitch open" into "audioswitch open", then maps "audioswitch open" into "com.reader.audioswitch open", and transmits "com.reader.audioswitch open" and "oc_yes" into the persistence container through the general data writing method.
Step 104: if the target data type of the target data is a non-preset data type, converting the target data type into a preset data type, calling a universal data writing method, and transmitting the writing method name and the target data of the preset data type into a storage space.
In the embodiment of the invention, if the target data type of the target data is a non-preset data type, the terminal equipment converts the target data type into the preset data type through a general type writing method, analyzes the writing method name into target identification information through a name conversion method, maps the target identification information into a container writing method name, and finally transmits the container writing method name and the target data of the preset data type into a persistence container.
For example, if the target data is YES, the writing method is named as "setaudioswitch open", the target data type is "BOOL", the terminal device converts the target data type from the BOOL type to the OC type through the general type writing method, encapsulates the "YES" into the "oc_yes", the name conversion method parses the "setaudioswitch open" into "audioswitch open", and then maps the "audioswitch open" into "com.reader.audioswitch open", and transfers the "com.reader.audioswitch open" and the "oc_yes" into the persistence container through the general data writing method.
Optionally, before determining whether the target data type of the target data is the preset data type, the terminal device generates attribute information, as shown in fig. 2:
Step 201: attribute information including target identification information and a target data type is generated.
In the embodiment of the invention, the terminal equipment generates attribute information by adopting a +load method, wherein the attribute information comprises identification information and data types of all data, and then the attribute information also comprises target identification information and target data types.
Step 202: according to the target identification information, a write method name and a read method name of the target identification information are obtained, and according to the target data type, a general type write method and a general type read method of the target data type are obtained, wherein the general type write method is used for converting the target data from the target data type to a preset data type, and the general type read method is used for converting the target data from the preset data type to the target data type.
In the embodiment of the invention, the terminal equipment acquires the write method name and the read method name of the target identification information according to the target identification information, and in one implementation mode, adds set before the name of the target identification information, and capitalizes the initial of the name of the target identification information to obtain the write method name; the name of the target identification information is the same as the name of the reading method. If the name of the target identification information is audioswitch open, the writing method is named setaudioswitch open, and the reading method is named audioswitch open. The present invention does not limit the specific acquisition process of the read method name and the write method name.
In the embodiment of the invention, a terminal device obtains a general type writing method and a general type reading method of a target data type according to the target data type, specifically, the target data type is converted into a fixed format to obtain a corresponding general type writing method and a general type reading method, if the target data type is BOOL, the general type writing method is a generalBoolSetter, and the general type reading method is a generalBoolGetter; if the target data type is Int, the general type writing method is generatlntlsetter, and the general type reading method is generatlntgetter.
The general type writing method is used for converting the target data from the target data type to the preset data type if the target data type of the target data is not the preset data type in the data writing process, and the general type reading method is used for converting the target data from the preset data type to the target data type if the read data type is different from the target data type in the data reading process.
Step 203: the addresses of the write method names are respectively directed to the universal type write methods, and the addresses of the read method names are directed to the universal type read methods.
In the embodiment of the invention, the terminal equipment points the address of the write method name to the universal type write method, and points the address of the read method name to the universal type read method, so that the universal type write method can be called by adopting the write method name, and the universal type read method can be called by adopting the read method name. In the embodiment of the invention, a method_setmaterialization method of run time is adopted, the address of the write method name is pointed to a universal type write method, and the address of the read method name is pointed to a universal type read method.
Step 204: the general type writing method is directed to the general data writing method, and the general type reading method is directed to the general data reading method, respectively.
In the embodiment of the invention, the terminal equipment points the universal type writing method to the universal data writing method and points the universal type reading method to the universal data reading method respectively, so that the data types of the target data transmitted into the persistence container are consistent, different rules are prevented from being established for the target data of different data types, and the efficiency and the accuracy are improved.
The application also provides a data reading method, which comprises the specific steps as shown in fig. 3:
step 301: and receiving a reading instruction, wherein the reading instruction comprises target identification information of data to be read.
In the embodiment of the invention, after the terminal device writes the target data into the storage space, the terminal device may receive a read instruction, where the read instruction includes target identification information of the data to be read. The reading instruction may be generated in response to a user operation, or may be generated by triggering a system program in a system operation process of the terminal device.
Step 302: and inquiring the target data type corresponding to the target identification information according to the pre-declared attribute information, wherein the attribute information comprises the identification information and the data type of each data.
In the embodiment of the present invention, the attribute information includes identification information of each data, specifically, each data corresponds to one attribute information, and the declaration process of the attribute information is noted in the foregoing.
The terminal device may query attribute information including the target identification information according to the target identification information in the read instruction, and further obtain a target data type corresponding to the target identification information from the attribute information, where in the embodiment of the present invention, the storage space may be a persistent container.
In an embodiment of the present invention, the data types may include an OC (object-C) type and a non-OC type, wherein the non-OC type includes, but is not limited to, a boolean type, an integer type, etc., and the OC type includes a string type, a NSObject type, etc. The target data type corresponding to the target identification information may be an OC type or a non-OC type.
Step 303: and reading data corresponding to the target identification information from the storage space by a general data reading method, and judging whether the read data type is the same as the target data type, wherein the data is the data of the preset data type written into the storage space.
In the embodiment of the invention, the terminal equipment can store a general data reading method, wherein the general data reading method is applicable to OC type data. The terminal equipment reads data corresponding to the target identification information from the storage space through a preset general data reading method, wherein the data is data of a preset data type written into the storage space. Specifically, the data types of the data read from the storage space are OC types, and since the target data type of the target data is not necessarily OC type, the terminal device is required to determine whether the read data type is the same as the target data type.
Step 304: if the read data type is different from the target data type, converting the read data into the data of the target data type to obtain the target data.
In the embodiment of the invention, as the data type read by the terminal equipment is the OC type, if the target data type is the non-OC type, the read data type is different from the target data type, the terminal equipment converts the read data of the OC type into the data of the target data type through a general type reading method, and obtains the target data of the target data type; if the target data type is OC type, the read data type is the same as the target data type, and the terminal equipment reads the target data of the target data type.
For example, if the target data type is a boolean type and belongs to a non-OC type, the target data type and the read OC type are different, and the terminal converts the read OC type data into boolean type data to obtain boolean type target data.
Optionally, reading data corresponding to the target identification information from the storage space, as shown in fig. 4, includes:
step 401: and determining a reading method name corresponding to the target identification information.
In the embodiment of the invention, the terminal equipment can obtain the general type reading method corresponding to the target data type through the target data type of the target data. In the general type reading method, the terminal device obtains a reading method name corresponding to the target identification information through_cmd (command prompt), wherein the reading method name is the same as the target identification information, for example, the target identification information is audioswitch open, and the reading method name is audioswitch open.
Step 402: the read method name is passed into the persistence container by a generic data read method.
In the embodiment of the invention, the terminal equipment transmits the reading method name into the storage space through the universal data reading method, and particularly, in the embodiment of the invention, the storage space is a persistent container. The storage space can also be a container such as NSUserDefaults, a database, a file and the like, and the invention does not limit the storage space specifically.
Step 403: and reading the data corresponding to the target identification information from the persistent container.
In the embodiment of the invention, after the terminal equipment transmits the reading method name corresponding to the target identification information into the persistence container, a preset general data reading method is called, and the data corresponding to the target identification information is read from the persistence container.
Optionally, converting the read method name by a name conversion method, and transferring the converted read method name into a persistence container, as shown in fig. 5, including:
step 501: the read method name is converted into a container read method name by a name conversion method.
In the embodiment of the invention, in the process of transmitting the reading method name into the persistent container, the terminal equipment analyzes the reading method name into target identification information through a name conversion method, and maps the target identification information into the container reading method name according to preset mapping information.
In the embodiment of the invention, the names of the reading method names are shorter, repeated names are easy to generate among the reading method names in the persistent container, the repeated probability can be reduced by converting the reading method names with shorter names into the container reading method names with longer names, data confusion is avoided, in addition, after the persistent container is upgraded, the original reading method names are not suitable for the updated persistent container, so that the adaptability of the reading method names can be improved by converting the reading method names into the container reading method names.
For example, the read method name may be audioswitch open, the terminal device parses the read method name into audioswitch open through a name conversion method, and then the name conversion method maps audioswitch open into com.
Step 502: the container read method name is passed into the persistence container by a generic data read method.
In the embodiment of the invention, the terminal equipment calls a general data reading method and transmits the converted container reading method name into the persistent container. Generally, the read data needs to call the target data which is written in advance, the target data is stored in the memory of the terminal equipment, and once the terminal equipment is powered off or is turned off accidentally, the target data in the memory disappears, so that the target data needs to be stored in a persistence container, and the permanence of the target data is ensured.
Optionally, if the read data type is different from the target data type, converting the read data into the data of the target data type by a general type reading method corresponding to the target data type.
In the embodiment of the invention, the target data type corresponding to the target data is OC type or non-OC type, but the data type read by the terminal equipment from the persistence container is OC type, in order to ensure that the target data keeps the original data type, the terminal equipment needs to judge whether the read data type and the target data type are the same, if the terminal equipment judges that the read data type is different from the target data type, the data of the OC type needs to be converted into the data of the non-OC type, and the general type reading method corresponds to the target data type, so that the conversion process is completed in the general type reading method; and if the terminal equipment judges that the read data type is the same as the target data type, acquiring the data obtained from the persistence container.
