Enum Constant Detail

Starting

public static final NonBlockingLockManager.RunState Starting

During startup. Tasks are NOT accepted.

Running

public static final NonBlockingLockManager.RunState Running

While running (aka open). Tasks are accepted and submitted for execution once they hold their locks.

Shutdown

public static final NonBlockingLockManager.RunState Shutdown

When shutting down normally. New tasks are not accepted but Futures are still monitored for completion and waiting tasks will eventually be granted their locks and execute on the delegate.

ShutdownNow

public static final NonBlockingLockManager.RunState ShutdownNow

When shutting down immediately. New tasks are not accepted, tasks waiting for their locks are cancelled (they will not execute) and Futures for running tasks are cancelled (they are interrupted).

Halted

public static final NonBlockingLockManager.RunState Halted

When halted. New tasks are not accepted. No tasks are waiting. Any Futures were cancelled.

Method Detail

values

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

Returns:

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

valueOf

public static NonBlockingLockManager.RunState 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

value

public int value()

isTransitionLegal

public boolean isTransitionLegal(NonBlockingLockManager.RunState newval)
