abstract class CLAttributeInfo extends Object
The abstract base class for the representation of attribute_info} structure. Classes representing individual attributes inherit this class. This file has representations for all attributes specified in JVM Spec Second Edition, including the ones that were added for JDK 1.5.

Attributes are used in the CLFile, CLFieldInfo, CLMethodInfo, and CLCodeAttribute structures of the class file. While there are many kinds of attributes, only some are mandatory; these include:

  • InnerClasses_attribute (class attribute)
  • Synthetic_attribute (class, field, and method attribute)
  • Code_attribute (method attribute)
  • Exceptions_attribute (method attribute)

CLEmitter implicitly adds the required attributes to the appropriate structure. The optional attributes have to be added explicitly using the CLEmitter methods addClassAttribute(), addFieldAttribute(), addMethodAttribute(), and addCodeAttribute().
