  • Enum Constant Details

    • DENSE

      public static final StorageType DENSE
      Dense storage. Use Dense to store small quantities of values, or values where zero is not common, or larger access times are unacceptable, or memory availability is high.

    • SPARSE

      public static final StorageType SPARSE
      Sparse storage. Use Sparse to store large quantities of values when most are zero and larger access times are acceptable and memory availability is low. Changing a zero value to a non-zero value is CPU-time-expensive

  • Method Details

    • values

      public static StorageType[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static StorageType 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
