  • 字段详细资料

    • api

      protected final int api
      The ASM API version implemented by this visitor. The value of this field must be one of Opcodes.ASM4 or Opcodes.ASM5.

    • av

      protected AnnotationVisitor av
      The annotation visitor to which this visitor must delegate method calls. May be null.

    • AnnotationVisitor

      public AnnotationVisitor(int api)
      Constructs a new AnnotationVisitor.
      参数:
      api - the ASM API version implemented by this visitor. Must be one of Opcodes.ASM4 or Opcodes.ASM5.

    • AnnotationVisitor

      public AnnotationVisitor(int api, AnnotationVisitor av)
      Constructs a new AnnotationVisitor.
      参数:
      api - the ASM API version implemented by this visitor. Must be one of Opcodes.ASM4 or Opcodes.ASM5.
      av - the annotation visitor to which this visitor must delegate method calls. May be null.

    • visit

      public void visit(String name, Object value)
      Visits a primitive value of the annotation.
      参数:
      name - the value className.
      value - the actual value, whose type must be Byte, Boolean, Character, Short, Integer , Long, Float, Double, String or Type or OBJECT or ARRAY sort. This value can also be an array of byte, boolean, short, char, int, long, float or double values (this is equivalent to using visitArray and visiting each array element in turn, but is more convenient).

    • visitEnum

      public void visitEnum(String name, String desc, String value)
      Visits an enumeration value of the annotation.
      参数:
      name - the value className.
      desc - the class descriptor of the enumeration class.
      value - the actual enumeration value.

    • visitAnnotation

      public AnnotationVisitor visitAnnotation(String name, String desc)
      Visits a nested annotation value of the annotation.
      参数:
      name - the value className.
      desc - the class descriptor of the nested annotation class.
      返回:
      a visitor to visit the actual nested annotation value, or null if this visitor is not interested in visiting this nested annotation. The nested annotation value must be fully visited before calling other methods on this annotation visitor.

    • visitArray

      public AnnotationVisitor visitArray(String name)
      Visits an array value of the annotation. Note that arrays of primitive types (such as byte, boolean, short, char, int, long, float or double) can be passed as value to visit. This is what ClassReader does.
      参数:
      name - the value className.
      返回:
      a visitor to visit the actual array value elements, or null if this visitor is not interested in visiting these values. The 'className' parameters passed to the methods of this visitor are ignored. All the array values must be visited before calling other methods on this annotation visitor.

    • visitEnd

      public void visitEnd()
      Visits the end of the annotation.
