Field Detail

jmxName

public final java.lang.String jmxName

shutdownBeforeCommitlog

public final boolean shutdownBeforeCommitlog

Set true if this executor should be gracefully shutdown before stopping the commitlog allocator. Tasks on executors that issue mutations may block indefinitely waiting for a new commitlog segment, preventing a clean drain/shutdown.

Method Detail

values

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

Returns:

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

valueOf

public static Stage 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

fromPoolName

execute

                            T result)

executor

public ExecutorPlus executor()

shutdownNow

public static void shutdownNow()

This method shuts down all registered stages.

shutdownAndAwaitMutatingExecutors

public static void shutdownAndAwaitMutatingExecutors(boolean interrupt,
                                                     long timeout,
                                                     java.util.concurrent.TimeUnit units)
                                              throws java.lang.InterruptedException,
                                                     java.util.concurrent.TimeoutException

Throws:

                            throws java.lang.InterruptedException,
                                   java.util.concurrent.TimeoutException

Throws:

java.lang.InterruptedException

java.util.concurrent.TimeoutException
