Enclosing Class:: Attributes

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:

Must contain at least one character
The first character must be alphanumeric (a-z, A-Z, 0-9)
All other characters must be alphanumeric, a '-' or a '_'

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:

"Created-By" - General main attribute, tool and version that created this Manifest file.
"Java-Bean" - Bean objects attribute, whether the entry is a Bean. Value is either "true" or "false".
"Magic" - Signing attribute, application specific signing attribute. Must be understood by the manifest parser when present to validate the jar (entry).

Name

public Name(String name)
            throws IllegalArgumentException,
                   NullPointerException

Parameters:
name - the name of the new Name
Throws:
IllegalArgumentException - if name isn't a valid String representation of a Name
NullPointerException - if name is null

equals
