# Class PrinterMessageFromOperator

java.lang.Object
javax.print.attribute.TextSyntax
javax.print.attribute.standard.PrinterMessageFromOperator

All Implemented Interfaces:
  `Serializable, Cloneable, Attribute, PrintServiceAttribute`

public final class PrinterMessageFromOperator extends TextSyntax implements PrintServiceAttribute
Class `PrinterMessageFromOperator` 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 information about or status of the printer, such as why it is unavailable or when it is expected to be available.

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

  - ### PrinterMessageFromOperator

    public PrinterMessageFromOperator(String message, Locale locale)
    Constructs a new printer message from operator attribute with the given message and locale.
    Parameters:
      `message` - the message
      `locale` - natural language of the text string. `null` is interpreted to mean the default locale as returned by `Locale.getDefault()`
    Throws:
      `NullPointerException` - if `message` is `null`

- ## Method Details

  - ### equals

    public boolean equals(Object object)
    Returns whether this printer 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 `PrinterMessageFromOperator`.
    3. This printer message from operator attribute's underlying string and `object`'s underlying string are equal.
    4. This printer 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 printer message from operator attribute, `false` otherwise

      - `Object.hashCode()`
      - `HashMap`

  - ### 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 `PrinterMessageFromOperator`, the category is class `PrinterMessageFromOperator` itself.

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

  - ### getName

    public final String getName()
    Get the name of the category of which this attribute value is an instance.

    For class `PrinterMessageFromOperator`, the category name is `"printer-message-from-operator"`.

    Specified by:
      `getName` in interface `Attribute`
    Returns:
      attribute category name
