Interface MethodTransform

All Superinterfaces:
ClassFileTransform<MethodTransform,MethodElement,MethodBuilder>
All Known Implementing Classes:
TransformImpl.ChainedMethodTransform, TransformImpl.MethodCodeTransform, TransformImpl.SupplierMethodTransform
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public non-sealed interface MethodTransform extends ClassFileTransform<MethodTransform,MethodElement,MethodBuilder>
A transformation on streams of MethodElement.

  • Field Details

    • ACCEPT_ALL

      static final MethodTransform ACCEPT_ALL
      A method transform that sends all elements to the builder.

  • Method Details

    • ofStateful

      static MethodTransform ofStateful(Supplier<MethodTransform> supplier)
      Create a stateful method transform from a Supplier. The supplier will be invoked for each transformation.
      Parameters:
      supplier - a Supplier that produces a fresh transform object for each traversal
      Returns:
      the stateful method transform

    • endHandler

      static MethodTransform endHandler(Consumer<MethodBuilder> finisher)
      Create a method transform that passes each element through to the builder, and calls the specified function when transformation is complete.
      Parameters:
      finisher - the function to call when transformation is complete
      Returns:
      the method transform

    • dropping

      static MethodTransform dropping(Predicate<MethodElement> filter)
      Create a method transform that passes each element through to the builder, except for those that the supplied Predicate is true for.
      Parameters:
      filter - the predicate that determines which elements to drop
      Returns:
      the method transform

    • transformingCode

      static MethodTransform transformingCode(CodeTransform xform)
      Create a method transform that transforms CodeModel elements with the supplied code transform.
      Parameters:
      xform - the method transform
      Returns:
      the class transform

    • resolve

      default ClassFileTransform.ResolvedTransform<MethodElement> resolve(MethodBuilder builder)
      Description copied from interface: ClassFileTransform
      Bind a transform to a builder. If the transform is chained, intermediate builders are created for each chain link. If the transform is stateful (see, e.g., ClassTransform.ofStateful(Supplier)), the supplier is invoked to get a fresh transform object.

      This method is a low-level method that should rarely be used by user code; most of the time, user code should prefer ClassFileBuilder.transform(CompoundElement, ClassFileTransform), which resolves the transform and executes it on the current builder.

      Specified by:
      resolve in interface ClassFileTransform<MethodTransform,MethodElement,MethodBuilder>
      Parameters:
      builder - the builder to bind to
      Returns:
      the bound result
      ImplSpec:
      The default implementation returns a resolved transform bound to the given method builder.

    • andThen

      default MethodTransform andThen(MethodTransform t)
      Description copied from interface: ClassFileTransform
      Chain this transform with another; elements presented to the builder of this transform will become the input to the next transform.
      Specified by:
      andThen in interface ClassFileTransform<MethodTransform,MethodElement,MethodBuilder>
      Parameters:
      t - the downstream transform
      Returns:
      the chained transform
      ImplSpec:
      The default implementation returns this method transform chained with another method transform from the argument. Chaining of two transforms requires to involve a chained builder serving as a target builder for this transform and also as a source of elements for the downstream transform.
