class:Attributes [NONE]

  • All Implemented Interfaces:
    Cloneable, Map<Object,Object>

    public class Attributes
    extends Object
    implements Map<Object,Object>, Cloneable
    
    The Attributes class maps Manifest attribute names to associated string values. Valid attribute names are case-insensitive, are restricted to the ASCII characters in the set [0-9a-zA-Z_-], and cannot exceed 70 characters in length. There must be a colon and a SPACE after the name; the combined length will not exceed 72 characters. Attribute values can contain any characters and will be UTF8-encoded when written to the output stream. See the JAR File Specification for more information about valid attribute names and values.

    This map and its views have a predictable iteration order, namely the order that keys were inserted into the map, as with LinkedHashMap.
