abstract class CLAttributeInfo
extends Object

Representation of attribute_info structure (JVM Spec Section 4.8). 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 ClassFile (CLFile), field_info (CLFieldInfo), method_info (CLMethodInfo), and Code_attribute (CLCodeAttribute) structures of the class file format. 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) CLAbsorber is capable of reading all attributes listed in this file. The ones which it does not recognize, it simply skips them and reports a warning to that extent. CLEmitter implicitly adds the required attributes to the appropriate structure. The optional attributes have to be added explicitly using the addClassAttribute(), addFieldAttribute(), addMethodAttribute(), and addCodeAttribute() methods in CLEmitter.
