   javassist.bytecode.annotation.AnnotationsWriter

AnnotationsWriter
public class AnnotationsWriter (Code)
A convenience class for constructing a ..Annotations_attribute. See the source code of the AnnotationsAttribute.Copier class.

The following code snippet is an example of use of this class: 

     ConstPool pool = ...;
 output = new ByteArrayOutputStream();
 writer = new AnnotationsWriter(output, pool);
 writer.numAnnotations(1);
 writer.annotation("Author", 2);
 writer.memberValuePair("name");
 writer.constValueIndex("chiba");
 writer.memberValuePair("address");
 writer.constValueIndex("tokyo");
 writer.close();
 byte[] attribute_info = output.toByteArray();
 AnnotationsAttribute anno
 = new AnnotationsAttribute(pool, AnnotationsAttribute.visibleTag,
 attribute_info);

The code snippet above generates the annotation attribute corresponding to this annotation: 

      @Author(name = "chiba", address = "tokyo")
