Thus, a feature defining "a first", "a second", and "a third" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise. All directional indications (such as up, down, left, right, front, back … …) in embodiments of the present application are merely used to explain the relative positional relationship, movement, etc. between the components in a particular gesture (as shown in the drawings), and if the particular gesture changes, the directional indication changes accordingly. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
For ease of understanding, the variate function and its parsing will be described first, where the variate function may have at least M parameters and at most N parameters to perform the operation (M < =n), and in the implementation of the interpreter, one of the heaviest steps is to convert the prefix expression into the prefix expression or the suffix expression, so as to facilitate computer processing. When using a shoving-hard algorism to convert a suffix expression into a suffix expression (i.e. an inverse Polish expression), the integer values over the interval where the parameter number pc of the variable parameter function is [ M, N ] can be resolved correctly, and in a function resolver implemented based on the dispatch field Algorithm, the boundaries of the parameters can be determined according to the number for a function of fixed parameters. When the number of the function parameters is uncertain, boundary information needs to be additionally provided, in one embodiment, the function analysis firstly needs to add boundary marks to the variable parameter function, the boundary marks are inserted into a queue firstly, then the queue is inserted according to a function analysis algorithm, the function real parameters are acquired according to the parameter boundary values when the function is analyzed, a result of executing the function is obtained, and the result is stacked as an operand to obtain a standard dispatching field algorithm expression. When parameters of the variable parameter function are not fixed, the method needs to rely on the input of a user, and for functions with the same functions and different parameters, different function names need to be provided, so that the uniformity of the function names is violated, and the user lacks flexibility in using the functions. Therefore, the application provides a variable parameter function analysis method which can well solve the problem that the real parameter number cannot be determined, thereby realizing the support of a function analyzer on the variable parameter function.
Referring to fig. 1, fig. 1 is a flow chart of a method for analyzing a variable parameter function according to a first embodiment of the present application. It should be noted that, if there are substantially the same results, the method of the present application is not limited to the flow sequence shown in fig. 1. As shown in fig. 1, the method comprises the steps of:
step S101: the method comprises the steps of obtaining an expression of a variable parameter function and description information of an embedded function in the variable parameter function, wherein the expression comprises a function name of the embedded function, a parameter delimiter of the embedded function and operators among the embedded functions, the parameter delimiter is adjacent to the function name and is used for indicating real parameters of the embedded function, the description information of the embedded function comprises the minimum parameter number and the maximum parameter number of the embedded function, and the variable parameter function comprises at least two embedded functions.
It should be noted that, in the field of computer science, a dispatching field algorithm is a method for parsing a mathematical expression, especially a suffix expression. The algorithm can output a character string of a suffix mark method or an abstract grammar tree structure, and is named as a dispatching field algorithm because the operation of the algorithm is similar to that of a railway dispatching field, a function expression is similar to a train on the railway, each carriage is an embedded function, the connection among the carriages is an operator, the dispatching field algorithm dispatches the embedded function to an output queue, dispatches the operator to operation Fu Zhan, and extracts and outputs the suffix expression which is finally analyzed from the output queue and the operator stack according to a certain rule during final output.
In step S101, before analyzing the variable parameter function, an expression of the variable parameter function needs to be obtained, where the expression of the variable parameter function includes a function name of an embedded function in the variable parameter function, a parameter delimiter, and an operator between the embedded functions, the parameter delimiter is adjacent to the function name and is used to indicate actual parameters of the embedded function, and the operator is used to indicate an operational relationship between the embedded functions. In this embodiment, the function name of the embedded function may have the same function name as the variable parameter function, and the parameter delimiters of the plurality of embedded functions may also be the same.
Further, the description information of the embedded function in the variable parameter function may include the minimum parameter number and the maximum parameter number of the embedded function, and in this embodiment, the variable parameter function includes at least two embedded functions, for example: the obtained expression of the variable parameter function comprises three embedded functions with the same function names, namely a first embedded function, a second embedded function and a third embedded function, wherein a first operator is arranged between the first embedded function and the second embedded function, a second operator is arranged between the second embedded function and the third embedded function, the description information of the embedded functions is the minimum parameter number 1 and the maximum parameter number 3, and the parameter delimiters of the first embedded function, the second embedded function and the third embedded function are the same, for example, the parameter delimiters are all the same in sign "(", the parameter decomposer of the first embedded function indicates that the real parameter of the first embedded function is a first parameter, the parameter decomposer of the second embedded function indicates that the real parameter of the second embedded function is a second parameter, and the parameter decomposer of the third embedded function indicates that the real parameter of the third embedded function is a third parameter.
Step S102: and analyzing the expression of the variable function, sequentially reading the elements in the expression, executing step S103 if the elements are the function names of the embedded functions, and executing step S104 if the elements are operators.
It should be noted that after the expression of the variable parameter function is obtained, analysis is performed according to a certain reading sequence, and in the analysis process, elements in the expression of the variable parameter function are sequentially judged, where the elements may include two kinds of elements: function name, operator of embedded function.
Step S103: analyzing the embedded function according to the function name, the parameter delimiter and the description information of the embedded function, acquiring an execution result of the embedded function, and putting the execution result into an operation queue as an operand.
In step S103, if the element currently obtained is the function name of the embedded function when the expression of the variable parameter function is analyzed, in this embodiment, the parameter delimiter is put into the operation queue first; after the parameter delimiters are put into an operation queue, determining parameters of the embedded function according to the parameter delimiters, and judging whether the number of the parameters is larger than or equal to the minimum number of the parameters and smaller than or equal to the maximum number of the parameters; if yes, sequentially placing the parameters and the function names of the embedded functions into an operation queue.
Still further, the method includes the steps of setting the parameter delimiter of the first embedded function in the operation queue if the element obtained at present is the function name of the embedded function, determining whether the number of the first parameters of the first embedded function determined by the parameter delimiter is greater than or equal to the minimum parameter number 1 and less than or equal to the maximum parameter number 3, and setting the first parameters and the function name of the first embedded function in the operation queue in sequence if the number of the parameters in the first parameters is 1 and the number of the parameters is within the minimum parameter number and the maximum parameter number.
In another embodiment, determining the parameters of the embedded function according to the parameter delimiters may further determine the elements read between two reads of the parameter delimiters as parameters of the embedded function.
Further, an execution result of the embedded function is obtained, the execution result is taken as an operand and put into an operation queue, a value of a parameter of the embedded function can be obtained, the embedded function is called, the execution result is obtained through operation, the first parameter is substituted into the first embedded function for calculation to obtain a first result, and the first result is taken as the operand and put into the operation queue. The analysis process of each embedded function is the same, when the acquired element is the function name of the embedded function, the embedded function is analyzed into a parameter delimiter, the real parameter of the embedded function and the execution result of the embedded function, and the parameter delimiter, the real parameter of the embedded function and the execution result of the embedded function are put into an operation queue as operands.
It should be noted that, in step S103, the number of real parameters of different embedded functions may be different, for example: the number of first parameters of the first embedded function may be 1, the number of second parameters of the second embedded function may be 2, and the number of third parameters of the third embedded function may be 3, wherein the third parameters may include the second parameters or the first parameters, and the second parameters may include the first parameters.
Step S104: the operation Fu Yaru operator stack.
In step S104, if the expression of the argument function is parsed, the element currently acquired is an operator. The operation Fu Yaru operator stack is performed. With the above example, when the first embedded function is parsed, the first operator after the first embedded function is obtained, and the operation Fu Yaru operator stack is performed.
Further, after stacking the operation Fu Yaru operator, an operand corresponding to an embedded function that is adjacent to the operator and whose execution result has been placed in the operation queue is inserted into the output queue.
Step S105: after the execution results of all the embedded functions adjacent to the operator are put in the operation queue, the operator is popped from the operation Fu Zhan, and the popped operator is inserted into the operation queue.
In this embodiment, after the analysis results of all the embedded functions adjacent to the operators are placed in the operation queue, and after the execution results are calculated according to the parameters of the embedded functions, when the output queue outputs the analysis results of the embedded functions, the operators are popped from the operation Fu Zhan, the popped operators are inserted into the operation queue, and then the analysis results are sequentially output.
Still further to the above description, when the first parameter is substituted into the first embedded function to calculate a first result, and the first operator is pushed into the operator stack, the second embedded function is parsed according to the method of parsing the first embedded function, and the second parameter of the second embedded function is substituted into the calculation to obtain a second result and put into the output queue, and then the first operator is popped out of the stack and output to the output queue, and then the second operator between the second embedded function and the third embedded function is obtained in the process of continuing parsing, and the second operator is pushed into the operation Fu Zhan, and then the third embedded function is obtained in the process of continuing parsing, and still the third embedded function is parsed according to the method described above, and after the third result of the third embedded function is output to the output queue, the second operator is popped out of the stack and added into the output queue, and after the parsing of all embedded functions of the variable parameter function is completed, the result is sequentially output.
