## Enum Cursor.Decision

- java.lang.Object
- - java.lang.Enum<Cursor.Decision>
  - - org.apache.cassandra.index.sasi.utils.trie.Cursor.Decision

- All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<Cursor.Decision>
  Enclosing interface:
    Cursor<K,V>

      public static enum Cursor.Decision
      extends java.lang.Enum<Cursor.Decision>

  The `Cursor.Decision` tells the `Cursor` what to do on each step while traversing the `Trie`. NOTE: Not all operations that work with a `Cursor` support all `Cursor.Decision` types

- - ### Enum Constant Summary

    Enum Constants
    Enum Constant and Description
    `CONTINUE` Continue with the traverse operation
    `EXIT` Exit the traverse operation
    `REMOVE` Remove the previously returned element from the `Trie` and continue
    `REMOVE_AND_EXIT` Remove the previously returned element from the `Trie` and exit from the traverse operation

  - ### Method Summary

    All Methods Static Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `static Cursor.Decision` | `valueOf(java.lang.String name)` Returns the enum constant of this type with the specified name.
    `static Cursor.Decision[]` | `values()` Returns an array containing the constants of this enum type, in the order they are declared.

    - #### EXIT

          public static final Cursor.Decision EXIT

      Exit the traverse operation

    - #### CONTINUE

          public static final Cursor.Decision CONTINUE

      Continue with the traverse operation

    - #### REMOVE

          public static final Cursor.Decision REMOVE

      Remove the previously returned element from the `Trie` and continue

    - #### REMOVE_AND_EXIT

          public static final Cursor.Decision REMOVE_AND_EXIT

      Remove the previously returned element from the `Trie` and exit from the traverse operation

  - ### Method Detail

    - #### values

          public static Cursor.Decision[] 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 (Cursor.Decision c : Cursor.Decision.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static Cursor.Decision 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
