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 Detail

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

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
