Enum FullGCMode

  • All Implemented Interfaces:
    Serializable, Comparable<FullGCMode>
    public enum FullGCMode
extends Enum<FullGCMode>
    During hardening of FullGC one can choose level type of garbage should be cleaned up. Ultimately the goal is to clean up all possible garbage. After hardening these modes might no longer be supported.

    • Enum Constant Detail

      • NONE

        public static final FullGCMode NONE
        no full GC is done at all

    • Method Detail

      • values

        public static FullGCMode[] 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 (FullGCMode c : FullGCMode.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static FullGCMode valueOf​(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:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null

      • getMode

        public static FullGCMode getMode​(int mode)
