Interface LoadedTypeInitializer

All Known Implementing Classes:
AgentBuilder.InitializationStrategy.SelfInjection.Dispatcher.InjectingInitializer, LoadedTypeInitializer.Compound, LoadedTypeInitializer.ForStaticField, LoadedTypeInitializer.NoOp
public interface LoadedTypeInitializer
Implementations of this interface explicitly initialize a loaded type. Usually, such implementations inject runtime context into an instrumented type which cannot be defined by the means of the Java class file format.

    Method
    Description
    boolean
    isAlive()
    Indicates if this initializer is alive and needs to be invoked.
    void
    onLoad(Class<?> type)
    Callback that is invoked on the creation of an instrumented type.

  • Method Details

    • onLoad

      void onLoad(Class<?> type)
      Callback that is invoked on the creation of an instrumented type. If the loaded type initializer is alive, this method should be implemented empty instead of throwing an exception.
      Parameters:
      type - The manifestation of the instrumented type.

    • isAlive

      boolean isAlive()
      Indicates if this initializer is alive and needs to be invoked. This is only meant as a mark. A loaded type initializer that is not alive might still be called and must therefore not throw an exception but rather provide an empty implementation.
      Returns:
      true if this initializer is alive.
