## Class JobMessageFromOperator

- java.lang.Object
- - javax.print.attribute.TextSyntax
  - - javax.print.attribute.standard.JobMessageFromOperator

- All Implemented Interfaces:
    Serializable, Cloneable, Attribute, PrintJobAttribute

      public final class JobMessageFromOperator
      extends TextSyntax
      implements PrintJobAttribute

  Class JobMessageFromOperator is a printing attribute class, a text attribute, that provides a message from an operator, system administrator, or "intelligent" process to indicate to the end user the reasons for modification or other management action taken on a job.

  A Print Job's attribute set includes zero instances or one instance of a JobMessageFromOperator attribute, not more than one instance. A new JobMessageFromOperator attribute replaces an existing JobMessageFromOperator attribute, if any. In other words, JobMessageFromOperator is not intended to be a history log. If it wishes, the client can detect changes to a Print Job's JobMessageFromOperator attribute and maintain the client's own history log of the JobMessageFromOperator attribute values.

  IPP Compatibility: The string value gives the IPP name value. The locale gives the IPP natural language. The category name returned by `getName()` gives the IPP attribute name.

          public JobMessageFromOperator(String message,
                                        Locale locale)

      Constructs a new job message from operator attribute with the given message and locale.
      Parameters:
        `message` - Message.
        `locale` - Natural language of the text string. null is interpreted to mean the default locale as returned by `Locale.getDefault()`
      Throws:

  - ### Method Detail

    - #### equals

          public boolean equals(Object object)

      Returns whether this job message from operator attribute is equivalent to the passed in object. To be equivalent, all of the following conditions must be true:
      1. `object` is not null.
      2. `object` is an instance of class JobMessageFromOperator.
      3. This job message from operator attribute's underlying string and `object`'s underlying string are equal.
      4. This job message from operator attribute's locale and `object`'s locale are equal.
      Overrides:
        `equals` in class `TextSyntax`
      Parameters:
        `object` - Object to compare to.
      Returns:
        True if `object` is equivalent to this job message from operator attribute, false otherwise.

    - #### getCategory

          public final Class<? extends Attribute> getCategory()

      Get the printing attribute class which is to be used as the "category" for this printing attribute value.

      For class JobMessageFromOperator, the category is class JobMessageFromOperator itself.

      Specified by:
        `getCategory` in interface `Attribute`
      Returns:
        Printing attribute class (category), an instance of class `java.lang.Class`.

    - #### getName

          public final String getName()
