# Interface TypeAnnotation.TypeArgumentTarget

All Superinterfaces:
  `TypeAnnotation.TargetInfo`

Enclosing interface:
  `TypeAnnotation`

public static sealed interface TypeAnnotation.TypeArgumentTarget extends TypeAnnotation.TargetInfo
Indicates that an annotation appears either on the i'th type in a cast expression, or on the i'th type argument in the explicit type argument list for any of the following: a new expression, an explicit constructor invocation statement, a method invocation expression, or a method reference expression.

- ## Method Summary

  Modifier and Type
  Method
  Description
  `Label`
  `target()`
  The label right before the `Instruction` corresponding to the cast expression, the new expression, the explicit constructor invocation statement, the method invocation expression, or the method reference expression.
  `int`
  `typeArgumentIndex()`
  For a cast expression, the value of the type_argument_index item specifies which type in the cast operator is annotated.

  ### Methods declared in interface TypeAnnotation.TargetInfo

- ## Method Details

  - ### target

    Label target()
    The label right before the `Instruction` corresponding to the cast expression, the new expression, the explicit constructor invocation statement, the method invocation expression, or the method reference expression.
    Returns:
      the label right before the instruction

  - ### typeArgumentIndex

    int typeArgumentIndex()
    For a cast expression, the value of the type_argument_index item specifies which type in the cast operator is annotated. A type_argument_index value of 0 specifies the first (or only) type in the cast operator. The possibility of more than one type in a cast expression arises from a cast to an intersection type. For an explicit type argument list, the value of the type_argument_index item specifies which type argument is annotated. A type_argument_index value of 0 specifies the first type argument.
    Returns:
      the index into the type arguments
