Enum PlanState

java.lang.Object

java.lang.Enum<PlanState>

com.whitestein.lsps.engine.dto.PlanState

All Implemented Interfaces:

Serializable, Comparable<PlanState>

public enum PlanState
extends Enum<PlanState>
implements Serializable

Enum class that represents plan state. Each plan can be only in one of the states INACTIVE, RUNNING, ACHIEVED, FAILED.

You can compare two PlanStates for equality with built-in Enum.equals(Object) or with faster == operator. This holds even if the class is deserialized from serialized form.

Method Detail

values

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

Returns:

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

valueOf

public static PlanState 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

canBeChangedFromState

public abstract boolean canBeChangedFromState(PlanState oldState)

Returns true if a plan can be changed from state oldState to this state.

Parameters:

oldState - old plan state

Returns:

true if a plan can be changed from state oldState to this state

canBeChangedToState

public final boolean canBeChangedToState(PlanState newState)

Returns true if a plan can be changed from this state to state newState.

Parameters:

newState - new plan state

Returns:

true if a plan can be changed from this state to state newState
