cn.sliew.milky.common.watchdog.ThreadWatchdogs

All Implemented Interfaces:

Serializable, Comparable<ThreadWatchdogs>

public enum ThreadWatchdogs
extends Enum<ThreadWatchdogs>

Method Summary

Modifier and Type	Method	Description
ThreadWatchdog	newInstance(long interval, long maxExecutionTime, LongSupplier relativeTimeSupplier, BiFunction<Long,Runnable,ScheduledFuture<?>> scheduler)	Returns an implementation that checks for each fixed interval if there are threads that have invoked ThreadWatchdog.register() and not ThreadWatchdog.unregister() and have been in this state for longer than the specified max execution interval and then interrupts these threads.
ThreadWatchdog	noop()
static ThreadWatchdogs	valueOf(String name)	Returns the enum constant of this type with the specified name.
static ThreadWatchdogs[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Method Detail

values

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

Returns:

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

valueOf

public static ThreadWatchdogs 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

newInstance

public ThreadWatchdog newInstance(long interval,
                                  long maxExecutionTime,
                                  LongSupplier relativeTimeSupplier,
                                  BiFunction<Long,Runnable,ScheduledFuture<?>> scheduler)

Returns an implementation that checks for each fixed interval if there are threads that have invoked ThreadWatchdog.register() and not ThreadWatchdog.unregister() and have been in this state for longer than the specified max execution interval and then interrupts these threads.

Parameters:

interval - The fixed interval to check if there are threads to interrupt

maxExecutionTime - The time a thread has the execute an operation.

relativeTimeSupplier - A supplier that returns relative time

scheduler - A scheduler that is able to execute a command for each fixed interval

noop

public ThreadWatchdog noop()

Returns:

A noop implementation that does not interrupt threads and is useful for testing and pre-defined grok expressions.
