      The opcode of this instruction.

    • visibleTypeAnnotations

      public List<TypeAnnotationNode> visibleTypeAnnotations
      The runtime visible type annotations of this instruction. This field is only used for real instructions (i.e. not for labels, frames, or line number nodes). This list is a list of TypeAnnotationNode objects. May be null.

    • invisibleTypeAnnotations

      public List<TypeAnnotationNode> invisibleTypeAnnotations
      The runtime invisible type annotations of this instruction. This field is only used for real instructions (i.e. not for labels, frames, or line number nodes). This list is a list of TypeAnnotationNode objects. May be null.
