Enum Constant Detail

Redistribute

public static final FailureMode Redistribute

Move on to functional nodes when nodes fail.

In this failure mode, the failure of a node will cause its current queue and future requests to move to the next logical node in the cluster for a given key.

Retry

public static final FailureMode Retry

Continue to retry a failing node until it comes back up.

This failure mode is appropriate when you have a rare short downtime of a memcached node that will be back quickly, and your app is written to not wait very long for async command completion.

Cancel

public static final FailureMode Cancel

Automatically cancel all operations heading towards a downed node.

Method Detail

values

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

Returns:

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

valueOf

public static FailureMode 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
