Principles of the technical implementation of the Java class library in the JSONITER Scala Core framework

JSONITER Scala Core is a high -performance Scala JSON library that is implemented by using the Java class library. JSONITER Scala Core's technical implementation principle is to provide efficient JSON parsing and serialized functions by combining the JSONITER Java library and SCALA language characteristics.The following is the step of implementation of JSONITER Scala Core: 1. First, JSONITER Scala Core uses the core components in the JSONITER JAVA library to process JSON data.JSONITER Java is a fast, low -memory JSON library. It uses code generation technology to achieve efficient analysis and serialization. 2. JSONITER Scala Core integrated the JSONITER JAVA library with the Scala through the SCALA macro system, so as to use the functions provided by JSONITER in the SCALA environment.The SCALA macro system allows to generate code during compilation, so as to avoid performance overhead during runtime. 3. During the compilation period, JSONITER Scala Core will automatically generate corresponding JSON parsing and serialized code according to the SCALA sample category class or tract defined by the user.These codes are inserted into the compiled bytecode through the SCALA macro system. 4. The generated code uses the API provided by the JSONITER JAVA library to analyze and serialize JSON data.The JSONITER JAVA library has achieved fast JSON processing speed by skipping unnecessary type inspections and the creation of temporary objects. Below is a simple example that shows how JSONITER Scala Core analyzes and serialized JSON data: scala import com.github.plokhotnyuk.jsoniter_scala.core._ case class Person(name: String, age: Int) // Analysis of json val json = """{"name": "John", "age": 30}""" val person = readFromString[Person](json) Println (Person) // Output: Person (John, 30) // Sequence to JSON val person = Person("John", 30) val json = writeToString(person) Println (json) // Output: {"name": "John", "Age": 30} In the above example, we define a sample class called Person, which have two fields: name and Age.We can analyze the JSON string as a Person object by calling the `ReadFromString` method, or call the` `wrotetastring` method to sequence the Person object to the JSON string. By using JSONITER Scala Core, we can efficiently process JSON data in SCALA applications.Its technical implementation principle is to use the performance advantages of the JSONITER JAVA library to combine the SCALA macro system to achieve high -performance JSON parsing and serialized functions.
