Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived from the embodiments given herein by one of ordinary skill in the art, are within the scope of the invention.
In the related art, in order to enable a system (e.g., an internet of things system) to implement a corresponding service logic, a technician may write a code corresponding to the service logic based on a scripting language (e.g., JavaScript, Lua). However, the use of scripting languages is more critical, and the requirements on technicians are relatively high, which in turn increases the cost of using and maintaining the system.
In order to solve the above problem, an embodiment of the present invention provides a function building method, which can be applied to an electronic device. For example, in the technical field of internet of things, the electronic device may be a central control device in an intelligent home, and the central control device may receive an event triggered by a user operation (for example, an operation of pressing an air conditioner switch by the user, or an operation of turning off a bedroom lamp by the user), and process the event according to a corresponding service logic. For example, when it is determined that the user presses the air conditioner switch, all doors and windows are closed; alternatively, when it is determined that the user turns off the bedroom light, the curtain of the bedroom is turned on.
The service logic needs to be preset by a user/technician, that is, based on the method provided by the embodiment of the present invention, the user/technician can set the central control device to have a function of executing the preset service logic only by using an SQL statement, that is, generate a λ function chain having the preset service logic. Correspondingly, when a user triggers a certain operation to generate an event (i.e., a data stream) corresponding to the preset service logic, the central control device may process the event based on the λ function chain to respond to the operation of the user. Compared with the scripting language, the use threshold of the SQL statement is lower, and the use and maintenance cost of the system is reduced.
Referring to fig. 1, fig. 1 is a flowchart of a function building method according to an embodiment of the present invention, where the method may include the following steps:
s101: and acquiring a Structured Query Language (SQL) statement for realizing the preset service logic.
S102: and analyzing the SQL statement to obtain a plurality of SQL statement objects.
S103: and generating a response type lambda function which has the same business logic with the SQL clause corresponding to each SQL statement object and is used as the lambda function to be processed.
S104: and combining the lambda functions to be processed to obtain a lambda function chain for realizing the preset service logic.
The function construction method provided by the embodiment of the invention can construct the response type lambda function chain with the same business logic as the SQL statement, namely, a user can set the system to have the function of executing the preset business logic through the SQL statement. Compared with the scripting language, the use threshold of the SQL statement is low, and the use and maintenance cost of the system is reduced.
For step S101, the preset service logic is determined by the user according to a requirement, for example, for a central control device in an intelligent home, the preset service logic may indicate that all doors and windows are closed when it is determined that the user presses an air conditioner switch; alternatively, the preset service logic may also indicate that when it is determined that the user turns off the bedroom light, then the bedroom curtain is turned on.
SQL is a database query and programming language that is a high-level, non-procedural programming language that allows users to work on high-level data structures with high expressive power and low usage thresholds.
For step S102, in an implementation manner, the SQL statement may be parsed based on the SQL parser to obtain a corresponding abstract syntax tree, and nodes in the abstract syntax tree represent each SQL statement object, that is, a plurality of SQL statement objects included in the SQL statement may be obtained.
For example, for the SQL statement "Select Person From Dept Where agent > 30", after parsing, a Column object (corresponding to the Select Person part), a From object (corresponding to the From Dept part), and a Where object (corresponding to the Where agent >30 part) can be obtained.
For step S103, each SQL statement object corresponds to an SQL clause.
In an SQL statement, a commonly used SQL clause may include: select, From, Where, Group By, and Order By. The Select clause is used for selecting some data from the data table; the From clause is used for specifying a table participating in the query and can also be used for specifying a generated intermediate table; the Where clause is used for setting conditions for selecting data, so that the selected data meet preset conditions; the Group By clauses are used for grouping data; the Order By clause is used for sorting the screening results, and the default is ascending.
For the above example, the SQL clause corresponding to the Column object (corresponding to the Select Person part) is a Select clause; the SQL clause corresponding to the From object (corresponding to the From Dept part) is a From clause; the Where object (corresponding to Where Age >30 section) corresponds to the SQL clause.
Where based on function-responsive programming, functions can be received as input parameters and output return values, i.e., mapping from one function to another can be achieved.
That is, in the embodiment of the present invention, for each SQL clause in the SQL statement, a corresponding (i.e., having a corresponding business logic) responsive λ function may be generated, so as to implement the function of the SQL clause through the λ function.
For example, taking the Where clause as an example, the filter function semantics in the function-response programming are the same as it, both indicating that the data is filtered according to the condition, i.e., both have the same business logic. Thus, the business logic of the Where clause may be implemented using the filter function.
For step S104, after determining each to-be-processed λ function, each to-be-processed λ function may be combined to obtain a λ function chain. Because each lambda function to be processed and the corresponding SQL clause have the same business logic, the lambda function chain obtained by combining the lambda functions to be processed can realize the business logic of the whole SQL clause.
In one embodiment, after the step S104, the method may further include the steps of:
the method comprises the following steps: and when receiving a data stream corresponding to the preset service logic, processing the data stream according to the lambda function chain to obtain a processing result.
In the embodiment of the present invention, after the λ function chain of the preset service logic is generated, when a data stream corresponding to the preset service logic is received, the data stream may be processed based on the λ function chain.
In one implementation, a data flow corresponding to a preset service logic represents an event that triggers the preset service logic. For example, for a central control device in an intelligent home, the preset service logic indicates that all doors and windows are closed when it is determined that a user presses an air conditioner switch, and correspondingly, an event corresponding to the preset service logic is an event corresponding to the user pressing the air conditioner switch; or, the preset service logic indicates that when it is determined that the user turns off the bedroom lamp, the curtain of the bedroom is turned on, and correspondingly, the event corresponding to the preset service logic is the event corresponding to the user turning off the bedroom lamp.
In one embodiment, the first step may include the following steps:
and when receiving the data stream corresponding to the preset service logic through the data receiving interface corresponding to the lambda function chain, calling the lambda function chain to process the data stream to obtain a processing result.
In the embodiment of the present invention, a corresponding data receiving interface may be provided for each λ function chain, for example, an Accept interface may be provided. When the electronic device receives the data stream through the data receiving interface, the corresponding λ function chain may be called to process the received data stream. That is, the λ function chain may be bound to a data stream of a preset service logic through the data receiving interface.
In one embodiment, referring to fig. 2, on the basis of fig. 1, the step S103 may include the following steps:
s1031: and acquiring a function template of a lambda function, which is constructed in advance based on a response function library and has the same business logic with the SQL clause corresponding to each SQL statement object.
S1032: and generating a variable of a corresponding lambda function based on the parameters of the SQL statement object.
S1033: and filling the generated variables into a function template to obtain the corresponding lambda function to be processed.
In the implementation of the invention, for each SQL clause, a function template of a λ function having the same business logic as the SQL clause may be constructed in advance based on the responsive function library.
For example, for the Where clause, the function template of the corresponding λ function constructed may be:
value- > responsive function library filter when (ctx- > filter. apply (ctx))
Wherein, the filter represents the function of the response function library, and the filter represents the variable with the type of the function, which is equivalent to the conditional expression of the where clause.
It will be appreciated that the result is now a function template for the lambda function, which is not filled with the variables of the function. That is, the filter function has not yet been instantiated.
Then, parameters of the SQL statement object, that is, variables of the SQL clause corresponding to the SQL statement object, may be determined to obtain variables to be filled into the function template. After the variables are filled into the function template, that is, the function template is instantiated, the lambda function (that is, the lambda function to be processed) capable of running can be obtained.
In one embodiment, the step S104 may include the following steps:
and combining the lambda functions to be processed according to the specified sequence of the corresponding SQL clauses to obtain a lambda function chain for realizing the preset service logic.
In the embodiment of the invention, according to the implementation principle of the SQL sentences, the SQL clauses contained in the SQL sentences have a specified sequence, so that the obtained lambda functions to be processed can be combined according to the specified sequence of the corresponding SQL clauses to obtain the lambda function chain.
In one implementation, for an SQL statement, the specified order between SQL clauses may be: from- > Where- > Group By- > Order By.
For example, the SQL statement entered by the user is: a select value from source order by value; the input data stream sequence is: {10,5, 22,1}. The response code obtained by analyzing the SQL statement is as follows:
context->orderBy.apply(
column.apply(
row.apply(
from.apply(context))))；
that is, each SQL clause (from, order by, select) is translated into a λ function of the same business logic. The output result after the code processing is as follows: {1,5, 10, 22}. As can be seen, the implemented business logic is the same as the SQL statement.

The self-defined function characteristic corresponds to a function template of a lambda function self-defined by a user. Based on the method, functions and syntax which are not possessed by the native SQL statement can be realized, so that the personalized requirements of the user are met.
