Technical Principles of the NextInpputs Framework in Java Class Libraries

The NextInputs framework is a verification framework for Java -class libraries. Its technical principles can be divided into three aspects: input data extraction, definition of verification rules and processing results. First, the NextInputs framework is obtained by providing a simple way to obtain input data.It supports extraction data from various sources, including table fields, JSON objects, and XML documents.Developers only need to call a simple method to easily extract the input data to the verification framework. Secondly, the NextInPuts framework allows users to define various verification rules to verify the effectiveness of the input data.Developers can use predetermined rules (such as non -empty, minimum value, maximum length, etc.), or they can customize rules to meet specific verification needs.These rules can be constructed by chain calls, making the verification code more concise and readable. Finally, the NextinPuts framework also provides the function of processing verification results.Developers can take corresponding actions according to the verification results, such as displaying error messages or executing other logic based on fields that failed to verify.The verification results are returned in the form of a simple Boolean value or an object containing error information for developers for further treatment. Below is an example code that uses the NextInputs framework for input verification: import com.github.yoojia.inputs.Inputs; import com.github.yoojia.inputs.TextValue; public class ValidationExample { public static void main(String[] args) { // Define a input data TextValue username = Inputs.text("John Doe"); // Create a NextInputs instance Inputs inputs = new Inputs(); // Add verification rules inputs.add (username, "username") .required ("Can't be empty") .minLength (5, "Not less than 5 characters")) .maxLength (20, "cannot exceed 20 characters"); // authenticating boolean isValid = inputs.test(); // Process verification results if (isValid) { System.out.println ("Effective input data"); } else { inputs.errors().forEach(System.err::println); } } } In the above example, we first created a `TextValue` instance to represent the user name input data.Then, we created a `Inputs` instance, and used the` ADD` method to add the input data and the corresponding field name to the verification framework.Then, we added three verification rules to the username: `Required` indicates that it cannot be empty.Finally, we use the `test` method to verify the input data and output the corresponding message according to the verification results. Through the NextInPuts framework, developers can easily define and verify the input data to ensure its effectiveness and integrity.It provides a simple and powerful way to process input verification, making the development process more efficient and reliable.
