  - getModifiers
```
public abstract int getModifiers()
```
    Obtains the modifiers of the member.
    
    Returns:
    
    modifiers encoded with javassist.Modifier.
    
    See Also:
    
    Modifier
  - setModifiers
```
public abstract void setModifiers(int mod)
```
    Sets the encoded modifiers of the member.
    
    See Also:

  - hasAnnotation
```
public boolean hasAnnotation(java.lang.Class clz)
```
    Returns true if the class has the specified annotation type.
    
    Parameters:
    
    clz - the annotation type.
    
    Returns:
    
    true if the annotation is found, otherwise false.
    
    Since:
    
    3.11
  - hasAnnotation
```
public abstract boolean hasAnnotation(java.lang.String annotationTypeName)
```
    Returns true if the class has the specified annotation type.
    
    Parameters:
    
    annotationTypeName - the name of annotation type.
    
    Returns:
    
    true if the annotation is found, otherwise false.
    
    Since:
    
    3.21
  - getAnnotation
```
public abstract java.lang.Object getAnnotation(java.lang.Class annotationType)
                                        throws java.lang.ClassNotFoundException
```
    Returns the annotation if the class has the specified annotation type. For example, if an annotation @Author is associated with this member, an Author object is returned. The member values can be obtained by calling methods on the Author object.
    
    Parameters:
    
    annotationType - the annotation type.
    
    Returns:
    
    the annotation if found, otherwise null.
    
    Throws:
    
    java.lang.ClassNotFoundException
    
    Since:
    
    3.11
  - getAnnotations
```
public abstract java.lang.Object[] getAnnotations()
                                           throws java.lang.ClassNotFoundException
```
    Returns the annotations associated with this member. For example, if an annotation @Author is associated with this member, the returned array contains an Author object. The member values can be obtained by calling methods on the Author object.
    
    Returns:
    
    an array of annotation-type objects.
    
    Throws:
    
    java.lang.ClassNotFoundException
    
    See Also:
    
    CtClass.getAnnotations()
  - getAvailableAnnotations
```
public abstract java.lang.Object[] getAvailableAnnotations()
```
    Returns the annotations associated with this member. This method is equivalent to getAnnotations() except that, if any annotations are not on the classpath, they are not included in the returned array.
    
    Returns:
    
    an array of annotation-type objects.
    
    Since:
    
    3.3
    
    See Also:
    
    getAnnotations(), CtClass.getAvailableAnnotations()
  - getName
```
public abstract java.lang.String getName()
```
    Obtains the name of the member.
    As for constructor names, see getName() in CtConstructor.
    
    See Also:
    
    CtConstructor.getName()
  - getSignature
```
public abstract java.lang.String getSignature()
```
    Returns the character string representing the signature of the member. If two members have the same signature (parameter types etc.), getSignature() returns the same string.
  - getGenericSignature
```
public abstract java.lang.String getGenericSignature()
```
    Returns the generic signature of the member.
    
    Since:
    
    3.17
    
    See Also:
    
    SignatureAttribute.toFieldSignature(String), SignatureAttribute.toMethodSignature(String), CtClass.getGenericSignature()
  - setGenericSignature
```
public abstract void setGenericSignature(java.lang.String sig)
```
    Sets the generic signature of the member.
    
    Parameters:
    
    sig - a new generic signature.
    
    Since:
    
    3.17
    
    See Also:
    
    SignatureAttribute.ObjectType.encode(), SignatureAttribute.MethodSignature.encode(), CtClass.setGenericSignature(String)
  - getAttribute
```
public abstract byte[] getAttribute(java.lang.String name)
```
    Obtains a user-defined attribute with the given name. If that attribute is not found in the class file, this method returns null.
    Note that an attribute is a data block specified by the class file format. See AttributeInfo.
    
    Parameters:
    
    name - attribute name
  - setAttribute
```
public abstract void setAttribute(java.lang.String name,
                                  byte[] data)
```
    Adds a user-defined attribute. The attribute is saved in the class file.
    Note that an attribute is a data block specified by the class file format. See AttributeInfo.
    
    Parameters:
    
    name - attribute name
    
    data - attribute value
