# Class Attributes

java.lang.Object
java.lang.classfile.Attributes

public final class Attributes extends Object
Attribute mappers for predefined (JVMS 4.7) and JDK-specific nonstandard attributes.

Unless otherwise specified, each mapper returned by methods in this class:

- is predefined in the JVMS instead of JDK-specific;
- does not permit multiple attribute instances in the same structure;
- the attribute has a data dependency on the constant pool.
