/**
 * A {@link ClassVisitor} that remaps types with a {@link Remapper}.
 *
 * 

This visitor has several limitations. A non-exhaustive list is the following: * *

    *
  • it cannot remap type names in dynamically computed strings (remapping of type names in * static values is supported). *
  • it cannot remap values derived from type names at compile time, such as *
      *
    • type name hashcodes used by some Java compilers to implement the string switch * statement. *
    • some compound strings used by some Java compilers to implement lambda * deserialization. *
