Class TypeWriter.MethodPool.Record.AccessBridgeWrapper

java.lang.Object
net.bytebuddy.dynamic.scaffold.TypeWriter.MethodPool.Record.AccessBridgeWrapper
All Implemented Interfaces:
TypeWriter.MethodPool.Record
Enclosing interface:
TypeWriter.MethodPool.Record
@Enhance public static class TypeWriter.MethodPool.Record.AccessBridgeWrapper extends Object implements TypeWriter.MethodPool.Record
A wrapper that appends accessor bridges for a method's implementation. The bridges are only added if TypeWriter.MethodPool.Record.apply(ClassVisitor, Implementation.Context, AnnotationValueFilter.Factory) is invoked such that bridges are not appended for methods that are rebased or redefined as such types already have bridge methods in place.

      instrumentedType - The instrumented type that defines the bridge methods and the bridge target.
      bridgeTarget - The bridge methods' target methods.
      bridgeTypes - A collection of all tokens representing all bridge methods.
      attributeAppender - The attribute appender being applied for the bridge target.

    • getSort

      public TypeWriter.MethodPool.Record.Sort getSort()
      Returns the sort of this method instrumentation.
      Specified by:
      getSort in interface TypeWriter.MethodPool.Record
      Returns:
      The sort of this method instrumentation.

    • getMethod

      public MethodDescription getMethod()
      Returns the method that is implemented where the returned method resembles a potential transformation. An implemented method is only defined if a method is not TypeWriter.MethodPool.Record.Sort.SKIPPED.
      Specified by:
      getMethod in interface TypeWriter.MethodPool.Record
      Returns:
      The implemented method.

    • getVisibility

      public Visibility getVisibility()
      The visibility to enforce for this method.
      Specified by:
      getVisibility in interface TypeWriter.MethodPool.Record
      Returns:
      The visibility to enforce for this method.

    • prepend

      public TypeWriter.MethodPool.Record prepend(ByteCodeAppender byteCodeAppender)
      Prepends the given method appender to this entry.
      Specified by:
      prepend in interface TypeWriter.MethodPool.Record
      Parameters:
      byteCodeAppender - The byte code appender to prepend.
      Returns:
      This entry with the given code prepended.

    • apply

      public void apply(org.objectweb.asm.ClassVisitor classVisitor, Implementation.Context implementationContext, AnnotationValueFilter.Factory annotationValueFilterFactory)
      Applies this method entry. This method can always be called and might be a no-op.
      Specified by:
      apply in interface TypeWriter.MethodPool.Record
      Parameters:
      classVisitor - The class visitor to which this entry should be applied.
      implementationContext - The implementation context to which this entry should be applied.
      annotationValueFilterFactory - The annotation value filter factory to apply when writing annotations.

    • applyHead

      public void applyHead(org.objectweb.asm.MethodVisitor methodVisitor)
      Applies the head of this entry. Applying an entry is only possible if a method is defined, i.e. the sort of this entry is not TypeWriter.MethodPool.Record.Sort.SKIPPED.
      Specified by:
      applyHead in interface TypeWriter.MethodPool.Record
      Parameters:
      methodVisitor - The method visitor to which this entry should be applied.

    • applyBody

      public void applyBody(org.objectweb.asm.MethodVisitor methodVisitor, Implementation.Context implementationContext, AnnotationValueFilter.Factory annotationValueFilterFactory)
      Applies the body of this entry. Applying the body of an entry is only possible if a method is implemented, i.e. the sort of this entry is TypeWriter.MethodPool.Record.Sort.IMPLEMENTED.

      Parameters:
      methodVisitor - The method visitor to which this entry should be applied.
      implementationContext - The implementation context to which this entry should be applied.
      annotationValueFilterFactory - The annotation value filter factory to apply when writing annotations.

    • applyAttributes

      public void applyAttributes(org.objectweb.asm.MethodVisitor methodVisitor, AnnotationValueFilter.Factory annotationValueFilterFactory)
      Applies the attributes of this entry. Applying the body of an entry is only possible if a method is implemented, i.e. the sort of this entry is TypeWriter.MethodPool.Record.Sort.DEFINED.
      Specified by:
      applyAttributes in interface TypeWriter.MethodPool.Record
      Parameters:
      methodVisitor - The method visitor to which this entry should be applied.
