public class MethodNode extends org.objectweb.asm.MethodVisitor
A node that represents a method.

  • Field Details

    • access

      public int access
      The method's access flags (see Opcodes). This field also indicates if the method is synthetic and/or deprecated.

    • name

      public String name
      The method's name.

    • desc

      public String desc
      The method's descriptor (see Type).

      public String signature
      The method's signature. May be null.

    • exceptions

      public List<String> exceptions
      The internal names of the method's exception classes (see Type.getInternalName()).

    • parameters

      public List<ParameterNode> parameters
      The method parameter info (access flags and name).

    • visibleAnnotations

      public List<AnnotationNode> visibleAnnotations
      The runtime visible annotations of this method. May be null.

    • invisibleAnnotations

      public List<AnnotationNode> invisibleAnnotations
      The runtime invisible annotations of this method. May be null.

    • visibleTypeAnnotations

      public List<TypeAnnotationNode> visibleTypeAnnotations
      The runtime visible type annotations of this method. May be null.

    • invisibleTypeAnnotations

      public List<TypeAnnotationNode> invisibleTypeAnnotations
      The runtime invisible type annotations of this method. May be null.

    • attrs

      public List<org.objectweb.asm.Attribute> attrs
      The non standard attributes of this method. May be null.

    • annotationDefault

      public Object annotationDefault
      The default value of this annotation interface method. This field must be a Byte, Boolean, Character, Short, Integer, Long, Float, Double, String or Type, or an two elements String array (for enumeration values), a AnnotationNode, or a List of values of one of the preceding types.

It can be strictly less when a method has synthetic parameters and when these parameters are ignored when computing parameter indices for the purpose of parameter annotations (see https://docs.oracle.com/javase/specs/jvms/se9/html/jvms-4.html#jvms-4.7.18).
