Enum TopicPriority

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<TopicPriority>
    public enum TopicPriority
extends java.lang.Enum<TopicPriority>
    Specifies the relative priority of topics stored in the Cache.

    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      High
      Messages in topic with this priority level are less likely to be deleted from the cache as the server frees system memory.
      Low
      Messages in topic with this priority level are the most likely to be deleted from the cache as the server frees system memory.
      Normal
      Messages in topic with this priority level are likely to be deleted from the cache as the server frees system memory only after those topics with Low priority.

    • Method Summary

      All Methods Static Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      static TopicPriority forValue​(int value)
      retreives the enum constant of the specified value, if exists.
      int getValue()
      Order is important in enums.By using getValue() method, each enum constant index can be found, just like array index.
      static TopicPriority valueOf​(java.lang.String name)
      Returns the enum constant of this type with the specified name.
      static TopicPriority[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.

    • Enum Constant Detail

      • Low

        public static final TopicPriority Low
        Messages in topic with this priority level are the most likely to be deleted from the cache as the server frees system memory.

      • Normal

        public static final TopicPriority Normal
        Messages in topic with this priority level are likely to be deleted from the cache as the server frees system memory only after those topics with Low priority. This is the default priority of the topic.

      • High

        public static final TopicPriority High
        Messages in topic with this priority level are less likely to be deleted from the cache as the server frees system memory.

    • Method Detail

      • values

        public static TopicPriority[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (TopicPriority c : TopicPriority.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static TopicPriority valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null

      • getValue

        public int getValue()
        Order is important in enums.By using getValue() method, each enum constant index can be found, just like array index.
        Returns:
        enum constant index

      • forValue

        public static TopicPriority forValue​(int value)
        retreives the enum constant of the specified value, if exists.
        Parameters:
        value - enum constant index
        Returns:
        enum constant
