Enum AbstractMasterJVM.State

java.lang.Object
  java.lang.Enum<AbstractMasterJVM.State>
      edu.rice.cs.util.newjvm.AbstractMasterJVM.State

All Implemented Interfaces:

Serializable, Comparable<AbstractMasterJVM.State>

Enclosing class:

AbstractMasterJVM

private static enum AbstractMasterJVM.State
extends Enum<AbstractMasterJVM.State>

Synchronization strategy: compare-and-swap guarantees that only one thread enters a STARTING, or QUITTING, or DISPOSED state. After that, the only state transitions out of STARTING/QUITTING occur in the same thread (or a single designated worker thread); all other threads must wait until the transition to FRESH or RUNNING.

Method Detail

values

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

Returns:

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

valueOf

public static AbstractMasterJVM.State 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
