      public void visit(int version, int access, String name, String signature, String superName, String[] interfaces)

      visit 在类中 RemappingClassAdapter
      参数:
      version - the class version.
      access - the class's access flags (see Opcodes). This parameter also indicates if the class is deprecated.
      name - the internal className of the class (see getInternalName).
      signature - the signature of this class. May be null if the class is not a generic one, and does not extend or implement generic classes or interfaces.
      superName - the internal of className of the super class (see getInternalName). For interfaces, the super class is Object. May be null, but only for the Object class.
      interfaces - the internal names of the class's interfaces (see getInternalName). May be null.

    • visitSource

      public void visitSource(String source, String debug)
      从类复制的说明: ClassVisitor
      Visits the srccode of the class.
      覆盖:

      参数:
      source - the className of the srccode file from which the class was compiled. May be null.
      debug - additional debug information to compute the correspondance between srccode and compiled elements of the class. May be null.

    • visitOuterClass

      public void visitOuterClass(String owner, String name, String desc)
      从类复制的说明: ClassVisitor

      参数:
      owner - internal className of the enclosing class of the class.
      name - the className of the method that contains the class, or null if the class is not enclosed in a method of its enclosing class.
      desc - the descriptor of the method that contains the class, or null if the class is not enclosed in a method of its enclosing class.

    • visitAnnotation

      public AnnotationVisitor visitAnnotation(String desc, boolean visible)

      visitAnnotation 在类中 RemappingClassAdapter
      参数:
      desc - the class descriptor of the annotation class.
      visible - true if the annotation is visible at runtime.
      返回:
      a visitor to visit the annotation values, or null if this visitor is not interested in visiting this annotation.

    • visitTypeAnnotation

      public AnnotationVisitor visitTypeAnnotation(int typeRef, TypePath typePath, String desc, boolean visible)
      从类复制的说明: ClassVisitor
      Visits an annotation on a type in the class signature.
      覆盖:
      visitTypeAnnotation 在类中 RemappingClassAdapter
      参数:
      typeRef - a reference to the annotated type. The sort of this type reference must be CLASS_TYPE_PARAMETER, CLASS_TYPE_PARAMETER_BOUND or CLASS_EXTENDS. See TypeReference.
      typePath - the path to the annotated type argument, wildcard bound, array element type, or static inner type within 'typeRef'. May be null if the annotation targets 'typeRef' as a whole.
      desc - the class descriptor of the annotation class.
      visible - true if the annotation is visible at runtime.
      返回:
      a visitor to visit the annotation values, or null if this visitor is not interested in visiting this annotation.

    • visitAttribute

      public void visitAttribute(Attribute attr)
      从类复制的说明: ClassVisitor
      Visits a non standard attribute of the class.
      覆盖:
      visitAttribute 在类中 ClassVisitor
      参数:
      attr - an attribute.

    • visitInnerClass

      public void visitInnerClass(String name, String outerName, String innerName, int access)
      从类复制的说明: ClassVisitor

      覆盖:
      visitInnerClass 在类中 RemappingClassAdapter
      参数:
      name - the internal className of an inner class (see getInternalName).
      outerName - the internal className of the class to which the inner class belongs (see getInternalName). May be null for not member classes.
      innerName - the (simple) className of the inner class inside its enclosing class. May be null for anonymous inner classes.
      access - the access flags of the inner class as originally declared in the enclosing class.

    • visitField

      public FieldVisitor visitField(int access, String name, String desc, String signature, Object value)
