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

CtClass.getAnnotations()

getAvailableAnnotations

public abstract java.lang.Object[] getAvailableAnnotations()
                                                    throws java.lang.ClassNotFoundException

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.

Throws:

java.lang.ClassNotFoundException

getName

public abstract java.lang.String getName()

Obtains the name of the member.

As for constructor names, see getName() in CtConstructor.

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.

getAttribute

                byte[] data)

Adds a user-defined attribute. The attribute is saved in the class file.
