Introduction

The purpose of this project

The purpose of this project is to summarize all the frequently used in Java development in one library, to avoid the situation of "the same function has been developed many times in different projects".

Utils

base

Package path: net.lamgc.utils.base
Introduction: Basic tools.

ArgumentsProperties - Used to parse the parameter list to generate parameter key-value pairs, which can quickly find parameters.

encrypt

Package path: net.lamgc.utils.encrypt
Introduction: Encrypt Utils contains encryption-related tools such as AES encryption and decryption, RSA encryption and decryption, and signatures. All tool classes are developed based on Java's own encryption suite.

AESEncrypt - AES encryption and decryption related classes.
DiffieHellmanEncrypt - DiffieHellman Key exchange algorithm class.
- Type of encryption algorithm supported by the shared key:
  - AES
  - RC2
  - RC4
  - Blowfish
  - DES
  - DES-EDE
  - HmacMD5
  - HmacSHA1
  - HmacSHA256
  - HmacSHA384
  - HmacSHA512
MessageDigestUtils - Message digest algorithm tool class.
- Supported message digest algorithms:
  - MD2
  - MD5
  - SHA-1
  - SHA-256
  - SHA-384
  - SHA-512
RSAEncrypt - RSA encryption and decryption tool class.
RSAEncryptWithAES - Data encryption and decryption tool class combining RSA and AES.
RSASign - RSA signature tool class.
- Supported signature algorithms:
  - MD2
  - MD5
  - SHA-1
  - SHA-224
  - SHA-256
  - SHA-384
  - SHA-512

event

Package path: net.lamgc.utils.event Introduction: Event Utils is a simple, general-purpose event system that can quickly add flexible event functions to a project.The event system is similar to the event system of the Bukkit API.

BasicEventHandlerList - Built-in default EventHandlerList.
EventExecutor - Event executor, used to post events to event methods.
EventHandler - An empty interface required to implement an event handler, used to identify that a class contains event methods.
EventObject - An empty interface required to implement events, used to identify a class as an event object, and passed to the event method as parameters.
EventHandlerList - List interface for storing event methods, which can be implemented to change the storage method.
EventHandlerObjectMap - Map interface that stores EventHandler objects.
EventInvokeException - It is used to wrap the information thrown by the event method, and it is handed over to the EventUncaughtExceptionHandler.
EventUncaughtExceptionHandler - An exception handling interface for handling event method exceptions.
HashHandlerObjectMap - Built-in default EventHandlerObjectMap, implemented by HashMap.
