Interface TypeAnnotation.LocalVarTargetInfo

Enclosing interface:
TypeAnnotationPREVIEW
public static sealed interface TypeAnnotation.LocalVarTargetInfo
LocalVarTargetInfo is a preview API of the Java platform.
Programs can only use LocalVarTargetInfo when preview features are enabled.
Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
Indicates a range of code array offsets within which a local variable has a value, and the index into the local variable array of the current frame at which that local variable can be found.

    Modifier and Type
    Method
    Description
    LabelPREVIEW
    endLabel()
    The given local variable has a value at indices into the code array in the interval [start_pc, start_pc + length), that is, between start_pc inclusive and start_pc + length exclusive.
    int
    index()
    The given local variable must be at index in the local variable array of the current frame.
    static TypeAnnotation.LocalVarTargetInfoPREVIEW
    of(LabelPREVIEW startLabel, LabelPREVIEW endLabel, int index)
    Returns local variable target info.
    LabelPREVIEW
    startLabel()
    The given local variable has a value at indices into the code array in the interval [start_pc, start_pc + length), that is, between start_pc inclusive and start_pc + length exclusive.

  • Method Details

    • startLabel

      LabelPREVIEW startLabel()
      The given local variable has a value at indices into the code array in the interval [start_pc, start_pc + length), that is, between start_pc inclusive and start_pc + length exclusive.
      Returns:
      the start of the bytecode section

    • endLabel

      LabelPREVIEW endLabel()
      The given local variable has a value at indices into the code array in the interval [start_pc, start_pc + length), that is, between start_pc inclusive and start_pc + length exclusive.
      Returns:
      the end of the bytecode section

    • index

      int index()
      The given local variable must be at index in the local variable array of the current frame. If the local variable at index is of type double or long, it occupies both index and index + 1.
      Returns:
      the index into the local variables

    • of

      static TypeAnnotation.LocalVarTargetInfoPREVIEW of(LabelPREVIEW startLabel, LabelPREVIEW endLabel, int index)
      Returns local variable target info.
      Parameters:
      startLabel - the code label indicating start of an interval where variable has value
      endLabel - the code label indicating start of an interval where variable has value
      index - index into the local variables
      Returns:
      local variable target info
