Example 1:
referring to fig. 2, embodiment 1 of the present invention provides a method for managing and controlling wind control rules, including:
step S100, constructing an abstract syntax tree by using a syntax parsing tool;
the above-mentioned grammar parsing tool is a software tool for parsing an inputted text or code into a grammar tree or other data structure, so that a program can perform more deep analysis and processing thereof. They are commonly used in compiler, interpreter, static analyzer, etc. applications.
The syntax parsing tools mentioned in this embodiment may include, but are not limited to ANTLR, bison, javaCC and peg.js, etc.
In this embodiment, ANTLR is used as a syntax analysis tool.
As described above, ANTLR (ANother Tool for Language Recognition) is a popular grammar parsing tool that supports multiple languages (including Java, c++, python, etc.) and platforms, and has the following features:
(1) Automatically generating a parser: ANTLR converts the input grammar rules into a parser of Java or other target language without having to manually write the parser code.
(2) Support a variety of parsing techniques: ANTLR supports various analysis techniques such as recursive descent, LL (x), LR (k), and the like, and can select the most appropriate technique as needed.
(3) Generating grammar error information with good readability: the ANTLR-generated parser can detect illegal syntax structures and generate error information that is easy to understand.
(4) Support nesting of grammar files: ANTLR supports combining multiple grammar files together so that common grammar rules can be easily reused.
(5) Has wide community support: ANTLR has a huge community of users and active communities, provides rich documents, example code, and extension plug-ins, and can help developers build syntax parsers faster.
The abstract syntax tree (Abstract Syntax Tree, AST) is a tree-shaped data structure that the programming language converts source code into a computer that is easy to understand and process during compilation or interpretation. It is a tree-like structure in which each node represents a syntax element in the original code, such as variables, functions, operators, etc.
Abstract syntax trees are typically constructed by analyzing source code, identifying various syntax structures in the source code, and attempting to translate them into a series of interrelated nodes. The nodes are connected by different types of edges to represent hierarchies and dependencies in the source code.
Unlike source code, the abstract syntax tree ignores some details and syntax rules, so it is more abstract and generalized. The method can be used in the fields of compiler optimization, code generation, static analysis and the like, and is one of important tools for program analysis and conversion.
In the compiler, an abstract syntax tree (Abstract Syntax Tree, AST) is a data structure generated from source code. It is a tree structure that represents the source code of a program and plays an important role in the compiler.
An abstract syntax tree, generated by a syntax Parser (Parser), can break the source code into smaller, more manageable parts and construct an AST node for each part. These nodes represent different elements in the grammar rules, such as expressions, function calls, variable declarations, etc. Relationships between nodes describe the hierarchy and dependencies between them.
By building an abstract syntax tree, a compiler can better understand the meaning of source code and can perform operations such as semantic analysis and code generation. In addition, the abstract syntax tree can be used for realizing functions of a code editor, intelligent prompt and the like, and has wide application in code development.
The process of constructing an abstract syntax tree is a process of parsing source code into syntax trees. It involves lexical and grammatical analysis of source code, which is then converted into a tree structure using a parser. The resulting abstract syntax tree is an abstract representation for the source code, facilitating further processing and analysis.
In step S100, an AST is created based on antlr, which is used to parse the inputted rule into a syntax tree and provide a mechanism for accessing these nodes. The implementation needs to implement the initiator method for each operator respectively, so that different operators can be processed in the subsequent rule matching process.
Step S200, loading all wind control rules based on the abstract syntax tree to form AST form rules corresponding to the abstract syntax tree;
step S300, determining a corresponding wind control rule according to order information, and accessing a node value in the abstract syntax tree of the AST form rule by using a monitor method so as to determine the feasibility of the wind control rule corresponding to the order information.
All rules are loaded during service initialization, and this part of work can be completed at system start-up, and the parsed AST (i.e. AST form rules) is stored for use during query.
And further, after order information provided by the user is obtained, determining a corresponding wind control rule according to the order information, and screening the wind control rule. Therefore, the node values in the abstract syntax tree of the AST form rule are accessed by using a displayer method so as to determine the feasibility of the wind control rule corresponding to the order information.
In short, the wind control rule engine is created based on the grammar parsing tool, and the threshold value, the range and the like of the rule are configured in the interface, so that the implementation of modifying codes every time is not needed, the efficiency is improved, and the risk is reduced.
Example 2:
referring to fig. 3, embodiment 2 of the present invention provides a method for managing and controlling wind control rules, which is based on embodiment 1 described above. The step S100, before constructing the abstract syntax tree by using the syntax parsing tool, further includes:
step S400, triggering a wind control rule construction flow according to the creation instruction;
step S500, according to the wind control rule construction flow, obtaining the wind control name and category of the wind control rule;
step S600, acquiring the wind control name and the corresponding action range information of the category, and determining the corresponding wind control template information;
and step S700, acquiring corresponding wind control screening conditions and wind control thresholds based on the wind control template information, and obtaining the wind control rule.
The user can create the wind control rule on the platform.
When creating, the creation instruction can be triggered to be generated, and the construction flow is started according to the instruction.
In the above construction process, various information needs to be acquired and set.
For example, the following procedure is possible:
1. setting a wind control name and determining a corresponding category;
2. setting a wind control throwing group, namely action range information, as a scope;
3. selecting a wind control template, namely wind control template information;
4. setting a wind control rule screening condition, namely criterion;
5. setting a wind control threshold;
thus obtaining the constructed wind control rule.
Further, referring to fig. 4, the step S300 of determining the corresponding wind control rule according to the order information, and accessing the node value in the abstract syntax tree of the AST form rule by using a monitor method so as to determine the feasibility of the wind control rule corresponding to the order information includes:
step S310, acquiring the order information to determine the corresponding wind control rule;
and triggering the evaluation and screening flow aiming at the wind control rule according to the order information submitted by the user.
The order information can determine the wind control rule for the user according to the order information.
Step S320, traversing the AST form rule, and accessing the node value of each word sequence in the AST form rule by using a motormeter method, so as to return a result to determine the feasibility of the wind control rule corresponding to the order information.
When a transaction user places an order, traversing the wind control rule, accessing the node value of each word sequence in the AST form rule by using a motormeter method, and determining whether the operation is feasible or not by returning a value.
Further, referring to fig. 5, the step S320 of accessing the node value of each word sequence in the AST form rule by using a monitor method to return a result to determine feasibility of the wind control rule corresponding to the order information includes:
step S321, obtaining attribution information corresponding to the order information;
step S322, judging whether the order information belongs to the action range information according to the attribution information;
step S323, if the order information belongs to the action range information, determining that the order information belongs to a department and/or a trading desk in the action range information, and determining feasibility of the wind control rule corresponding to the order information based on the returned result.
When the transaction user orders, the wind control rule is traversed, the scope (action range information) is checked first to see whether the current order information belongs to the department and/or the transaction platform of the rule, if not, the current order information is skipped directly.
In the above steps, it is necessary to traverse the wind control rule and check whether the current order belongs to the department and exchange of the rule, i.e. the attribution situation. This process may be implemented by the following logic steps:
traversing the wind control rule, and executing the following operations on the wind control rule:
the scope attribute of the rule is checked to determine if its affiliated department and exchange match the current order.
If so, the AST created by antlr is used to parse the criterion attribute of the rule and convert it to an executable bootean expression.
It is checked whether the bootan expression is true. If yes, the order meets the screening condition of the rule, and the next step is continuously executed; otherwise, the rule is skipped.
If all rules have been traversed and no matching rule is found, the order fails the pneumatic screening and no order is allowed.
In the above procedure, it is necessary to parse the criterion attribute of the rule using the AST created by ANTLR and convert it into an executable bootean expression. Therefore, the screening conditions of the rules can be converted into codes which can be understood and executed by a computer, and whether the order meets the screening conditions can be conveniently judged. At the same time, care must be taken to follow a certain order when traversing the rules to ensure that all rules are properly checked.
Further, referring to fig. 6, after determining that the order information belongs to the department and/or the transaction table in the scope information in step S323, the method further includes:
step S324, transaction element information corresponding to the order information is obtained;
step S325, judging whether the transaction element information accords with wind control screening conditions;
step S326, if the transaction element information accords with the wind control screening condition, determining the feasibility of the wind control rule corresponding to the order information based on the return result.
The trade factor of the order is determined whether or not criterion is satisfied.
The form thereof may be, for example:
"Instrument_class in ('BOND') and instrument_subs in ('LGB'), and judging whether the order meets the product BOND or not by using the analysis rule of 1, and judging whether the order is a local institution BOND or not.
Aiming at the steps, the method needs to analyze the transaction elements in the order and match with the screening conditions defined in the rules so as to judge whether the order meets the requirement of the rules. The specific implementation steps are as follows:
(1) The regular character string is converted into an Abstract Syntax Tree (AST) using an ANTLR generation lexical and grammatical parser.
(2) The scope and criterion node information of the rule is obtained from AST, and is analyzed and stored. The scope node comprises department and transaction table information to which the rule is applicable; the criterion node contains screening conditions, i.e., constraints on the transaction elements that the order needs to satisfy.
(3) And analyzing the information of the order transaction elements, such as the information of the product types, the sub-types and the like in the order.
(4) And matching the order transaction elements with screening conditions in the rules, and judging whether the order meets the rule requirements. An ANTLR generated monitor method may be used to traverse an AST, with matching logic implemented by invoking a different monitor method for each expression node.
(5) And if the order meets the rule requirement, allowing the order, otherwise, refusing the order.
It should be noted that in implementing the above steps, it is necessary to consider that a rule may include a plurality of conditions, and that logical operators (e.g. and, or, etc.) may exist between the conditions. Therefore, the matching results of the respective conditions need to be combined using boolean logic operators in the matching process to obtain the final matching result. In addition, in order to improve the matching efficiency, rules and order transaction elements can be preprocessed, common condition values are cached in advance, and repeated analysis and comparison are avoided.
Further, referring to fig. 7, in step S326, after the transaction element information meets the wind control screening condition, the method further includes:
step S327, judging whether the order information can trigger the wind control threshold;
step S328, if the order information can trigger the wind control threshold, judging that the wind control rule corresponding to the order information is not feasible;
step S329, if the order information cannot trigger the wind control threshold, determining that the wind control rule corresponding to the order information is feasible.
And judging whether the order triggers the threshold or not according to the judgment of the wind control threshold, and if so, not allowing the order to be placed.
In the wind control rule, the threshold may refer to a limit of data such as accumulated transaction amount or amount over a certain period. For example: a department or exchange can only trade 100 tens of thousands of dollars of products in one month, and if this limit is exceeded, the department or exchange's transaction rights will be suspended or cancelled. This limitation is a threshold.
For order screening, if an order involves a department or exchange, then the threshold information for that department or exchange needs to be involved in the risk assessment of the order. When the aggregate amount reaches a certain threshold, the order is rejected. The specific threshold value can be set according to actual conditions.
In the above step, it is necessary to determine whether the order triggers the wind control threshold, and if so, the order is not allowed. The specific implementation logic is as follows:
(1) Traversing all the wind control rules to find the rules related to the order.
(2) For each matched rule, threshold information and accumulated amount information thereof are acquired.
(3) And judging whether the transaction elements of the order meet the screening conditions of the rule, and if not, skipping the rule.
(4) If the screening conditions are met, the elements of interest for the rule are obtained from the order and accumulated.
(5) Checking whether the accumulated quantity exceeds the threshold value of the rule, if so, rejecting the order and returning a reject reason; otherwise, go on traversing other rules.
(6) If all rules have been traversed and no threshold for any rule has been triggered, the order is accepted and a success message is returned.
It should be noted here that, in order to avoid repetition of counting, when processing an order, the order should be first de-duplicated with the already matched rule, and only the non-matched rule should be counted. Meanwhile, in the case of performing the accumulation operation, security problems in the concurrent case should be considered, and the thread-safe data structure may be used to store the accumulated amount information of each rule.
The execution of the above step S300 may achieve the following technical effects:
(1) The wind control rules can be described by using unified grammar, so that the condition that different developers adopt different modes to realize the wind control rules is avoided, and the maintainability and expandability of the rules are improved.

Example 3:
referring to fig. 8, embodiment 3 of the present invention provides a method for managing and controlling wind control rules, based on embodiment 1 above, the step S100 of constructing an abstract syntax tree using a syntax parsing tool includes:
step S110, defining grammar rules of the grammar parsing tool;
step S120, generating a parser code based on the grammar rules by using the grammar parsing tool;
step S130, creating node classes in the abstract syntax tree;
step S140, defining a motormeter method corresponding to the node class and the node class;
and step S150, combining the node class and the initiator method in the parser code, and constructing the abstract syntax tree by using the syntax parsing tool.
The process of constructing the abstract syntax tree is the process of parsing the source code into the syntax tree. It involves lexical and grammatical analysis of source code, which is then converted into a tree structure using a parser. The resulting abstract syntax tree is an abstract representation for the source code, facilitating further processing and analysis.
For example, an abstract syntax tree is constructed, the steps of which can be as follows:
(1) Syntax rules defining ANTLR: first, a set of wind control rules that conform to the ANTLR grammar rules needs to be defined so that the ANTLR can correctly parse the rule text. Defining grammar rules requires compliance with the ANTLR grammar specification, for example using ": "represents a relationship between a rule name and an expression; the use of "|" indicates a relationship between a plurality of options, and so on.
(2) Using ANTLR to generate parser code: by running the ANTLR tool, a corresponding parser code may be automatically generated, which may read the rule text and convert it into an AST structure.
(3) Creating an AST node: when ANTLR parses the rule, the rule text is converted into an abstract syntax tree. Each node represents a rule element such as an operator, operand, variable name, etc. It is necessary to create corresponding AST node classes for representing different types of AST nodes and implement a series of methods for these node classes, such as an access method, a judgment method, etc.
(4) The method for realizing the initiator comprises the following steps: for an already defined AST node, a monitor method needs to be implemented, which is used to traverse the AST tree node, access different types of nodes, and perform corresponding operations. Where the visit method is used to process a single node and the visitChildren method is used to traverse all children of the node.
(5) Generating AST: in the parser code, an AST node class and a initiator method need to be combined, and a complete abstract syntax tree is constructed by using a syntax tree construction tool provided by ANTLR. Finally, the wind control rule can be judged and processed by using the generated AST.
The steps can help realize the process of converting the wind control rule text into executable and evaluable codes. In particular, the ANTLR tool can help define and parse the grammar of the wind control rules and generate corresponding parser codes, while an abstract grammar tree (AST) can help convert rule text into an easily handled, executable data structure.
Through the technologies, a self-defined wind control rule engine can be realized, and rules can be quickly written and modified to adapt to different business requirements. Meanwhile, because the abstract syntax tree has the characteristics of easy understanding and operation, various statistics and analysis operations such as calculation rule complexity, optimization rule matching and the like can be performed on AST, so that the performance and efficiency of the wind control system are further improved.
