Class Attributes.Name

public static class Attributes.Name extends Object

Represents a name of a Manifest Attribute. Defines a couple of well know names for the general main attributes, stand alone application attributes, applet attributes, extension identification attributes, package versioning and sealing attributes, file contents attributes, bean objects attribute and signing attributes. See the

The characters of a Name must obey the following restrictions:

When comparing Names (with equals) all characters are converted to lowercase. But you can get the original case sensitive string with the toString() method.

Most important attributes have a constant defined in this class. Some other attributes used in Manifest files are:

Since: 1.2
