public interface AsmVisitorWrapper
A class visitor wrapper is used in order to register an intermediate ASM ClassVisitor which is applied to the main type created by a DynamicType.Builder but not to any AuxiliaryTypes, if any.

    • NO_FLAGS

      static final int NO_FLAGS
      Indicates that no flags should be set.

    • mergeWriter

      int mergeWriter(int flags)
      Defines the flags that are provided to any ClassWriter when writing a class. Typically, this gives opportunity to instruct ASM to compute stack map frames or the size of the local variables array and the operand stack. If no specific flags are required for applying this wrapper, the given value is to be returned.
      Parameters:
      flags - The currently set flags. This value should be combined (e.g. flags | foo) into the value that is returned by this wrapper.
      Returns:
      The flags to be provided to the ASM ClassWriter.
    • mergeReader

      int mergeReader(int flags)
      Defines the flags that are provided to any ClassReader when reading a class if applicable. Typically, this gives opportunity to instruct ASM to expand or skip frames and to skip code and debug information. If no specific flags are required for applying this wrapper, the given value is to be returned.
      Parameters:
      flags - The currently set flags. This value should be combined (e.g. flags | foo) into the value that is returned by this wrapper.
      Returns:
      The flags to be provided to the ASM ClassReader.
    • wrap

      org.objectweb.asm.ClassVisitor wrap(TypeDescription instrumentedType, org.objectweb.asm.ClassVisitor classVisitor, Implementation.Context implementationContext, TypePool typePool, FieldList<FieldDescription.InDefinedShape> fields, MethodList<?> methods, int writerFlags, int readerFlags)
      Applies a ClassVisitorWrapper to the creation of a DynamicType.
      Parameters:
      instrumentedType - The instrumented type.
      classVisitor - A ClassVisitor to become the new primary class visitor to which the created DynamicType is written to.
      implementationContext - The implementation context of the current instrumentation.
      typePool - The type pool that was provided for the class creation.
      fields - The instrumented type's fields.
      methods - The instrumented type's methods non-ignored declared and virtually inherited methods.
      writerFlags - The ASM ClassWriter flags to consider.
      readerFlags - The ASM ClassReader flags to consider.
      Returns:
      A new ClassVisitor that usually delegates to the ClassVisitor delivered in the argument.
