apex常用英文术语
Apex is a popular programming language used in Salesforce development. As with any programming language, there are several commonly used English terms that are specific to Apex. Understanding these terms can be crucial for developers to effectively write and maintain Apex code.
1. Object: In Apex, an object is a data structure that represents a real-world entity such as a customer, contact, or opportunity. Objects are like database tables and are used to store and manipulate data.
2. Class: In Apex, a class is a blueprint or template for creating objects. It defines the properties (variables) and behaviors (methods) that an object of that class will have.
3. Method: A method is a block of code that performs a specific action in Apex. Methods are defined within a class and can be called and executed as needed.
4. Variable: Variables are used to store data in Apex. They can hold different types of data, such as text, numbers, or Boolean
values, and are given a name to refer to them within the code.
5. SOQL: SOQL stands for Salesforce Object Query Language. It is a query language used to retrieve data from Salesforce objects, similar to SQL in traditional databases.
6. DML: DML stands for Data Manipulation Language. In Apex, DML is used to insert, update, delete, and retrieve records in Salesforce databases.
7. Trigger: A trigger is a piece of code that is executed before or after a record is inserted, updated, or deleted in Salesforce. Triggers are often used to enforce business rules and automate processes.
8. Governor Limits: Apex has specific limits imposed by Salesforce to ensure efficient use of resources. These limits restrict the amount of resources (such as CPU time, heap size, and database queries) that a single transaction or execution context can consume.
9. Exception: An exception is an unexpected event or error that
occurs during the execution of Apex code. Exceptions can be caught and handled to prevent the code from crashing and to provide meaningful error messages.
10. Apex Test: Apex tests are written to validate the functionality and behavior of Apex code. They ensure that the code meets the requirements and performs as expected.
These are just a few of the commonly used English terms in Apex. Familiarizing oneself with these terms and their meanings is essential for any developer working with Apex to write efficient and effective code.。
