Interface IInjector

public interface IInjector
Patch classes should implement this interface and be declared as services in the META-INF/services folder (or through modules in Java 9+, but only Java 8 is officially supported).

    Description
    void
    inject(org.objectweb.asm.tree.ClassNode clazz, org.objectweb.asm.tree.MethodNode method)
    This method is to be called by the launcher after identifying the right class and method to patch.
    String
    methodDesc()
    This should return the target method's descriptor.
    String
    methodName()
    This is used to identify the method to transform within the class.
    String
    name()
     
    default String
    reason()
     
    String
    targetClass()
    This is used to identify which classes should be altered, and on which class should this injector operate.

  • Method Details

    • name

      String name()
      Returns:
      name of injector, for logging

    • reason

      default String reason()
      Returns:
      reason for this patch, for logging

    • targetClass

      String targetClass()
      This is used to identify which classes should be altered, and on which class should this injector operate. Class name should be dot-separated, for example "net.minecraft.client.Minecraft".
      Returns:
      class to transform

    • methodName

      String methodName()
      This is used to identify the method to transform within the class. It should return the name of target.
      Returns:
      method to transform

    • methodDesc

      String methodDesc()
      This should return the target method's descriptor. Methods in Java may have the same name but different parameters: a descriptor compiles that information, as well as the return type, in as little space as possible. Examples:
      • (IF)V - returns void, takes in int and float
      • (Ljava/lang/Object;)I - returns int, takes in a java.lang.Object
      • (ILjava/lang/String;)[I - returns int[], takes in an int and a String
      See ASM's documentation for a more detailed explanation.
      Returns:
      descriptor of method to target.

    • inject

      void inject(org.objectweb.asm.tree.ClassNode clazz, org.objectweb.asm.tree.MethodNode method)
      This method is to be called by the launcher after identifying the right class and method to patch. The overriding method should contain the actual patching logic.
      Parameters:
      clazz - the ClassNode currently being patched
      method - the MethodNode of method currently being patched
