Class ClassRemapper

java.lang.Object
org.objectweb.asm.ClassVisitor
org.objectweb.asm.commons.ClassRemapper
public class ClassRemapper extends org.objectweb.asm.ClassVisitor
A ClassVisitor that remaps types with a 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.

  • Field Details

    • remapper

      protected final Remapper remapper
      The remapper used to remap the types in the visited class.

    • className

      protected String className
      The internal name of the visited class.

  • Constructor Details

    • ClassRemapper

      public ClassRemapper(org.objectweb.asm.ClassVisitor classVisitor, Remapper remapper)
      Constructs a new ClassRemapper. Subclasses must not use this constructor. Instead, they must use the ClassRemapper(int,ClassVisitor,Remapper) version.
      Parameters:
      classVisitor - the class visitor this remapper must delegate to.
      remapper - the remapper to use to remap the types in the visited class.

    • ClassRemapper

      protected ClassRemapper(int api, org.objectweb.asm.ClassVisitor classVisitor, Remapper remapper)
      Constructs a new ClassRemapper.
      Parameters:
      api - the ASM API version supported by this remapper. Must be one of the ASMx values in Opcodes.
      classVisitor - the class visitor this remapper must delegate to.
      remapper - the remapper to use to remap the types in the visited class.
