public sealed interface CodeBuilder extends ClassFileBuilderPREVIEW<CodeElementPREVIEW,CodeBuilderPREVIEW> permits CodeBuilder.BlockCodeBuilderPREVIEW (not exhaustive)
CodeBuilder is a preview API of the Java platform.
Programs can only use CodeBuilder when preview features are enabled.
Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
A builder for code attributes (method bodies). Builders are not created directly; they are passed to handlers by methods such as MethodBuilder.withCode(Consumer)PREVIEW or to code transforms. The elements of a code can be specified abstractly, by passing a CodeElementPREVIEW to ClassFileBuilder.with(ClassFileElement)PREVIEW or concretely by calling the various withXxx methods.

  • Method Details

    • original

      Returns the CodeModelPREVIEW representing the method body being transformed, if this code builder represents the transformation of some CodeModelPREVIEW.
      Returns:
      the CodeModelPREVIEW representing the method body being transformed, if this code builder represents the transformation of some CodeModelPREVIEW
    • newLabel

      LabelPREVIEW newLabel()
      Returns a fresh unbound label.
      Returns:
      a fresh unbound label
    • startLabel

      LabelPREVIEW startLabel()
      Returns the label associated with the beginning of the current block. If the current CodeBuilderPREVIEW is not a "block" builder, such as those provided by block(Consumer) or ifThenElse(Consumer, Consumer), the current block will be the entire method body.
      Returns:
      the label associated with the beginning of the current block
    • endLabel

      LabelPREVIEW endLabel()
      Returns the label associated with the end of the current block. If the current CodeBuilderPREVIEW is not a "block" builder, such as those provided by block(Consumer) or ifThenElse(Consumer, Consumer), the current block will be the entire method body.
      Returns:
      the label associated with the end of the current block
    • receiverSlot

      int receiverSlot()
      Returns the local variable slot associated with the receiver..
      Returns:
      the local variable slot associated with the receiver
      Throws:
      IllegalStateException - if this is not a static method
    • parameterSlot

      int parameterSlot(int paramNo)
      Returns the local variable slot associated with the specified parameter.. The returned value is adjusted for the receiver slot (if the method is an instance method) and for the requirement that long and double values require two slots.
      Parameters:
      paramNo - the index of the parameter
      Returns:
      the local variable slot associated with the specified parameter
    • allocateLocal

      int allocateLocal(TypeKindPREVIEW typeKind)
      Returns the local variable slot of a fresh local variable. This method makes reasonable efforts to determine which slots are in use and which are not. When transforming a method, fresh locals begin at the maxLocals of the original method. For a method being built directly, fresh locals begin after the last parameter slot.

      If the current code builder is a "block" code builder provided by block(Consumer), ifThen(Consumer), or ifThenElse(Consumer, Consumer), at the end of the block, locals are reset to their value at the beginning of the block.

      Parameters:
      typeKind - the type of the local variable
      Returns:
      the local variable slot of a fresh local variable
