All Implemented Interfaces:

Serializable, Comparable<EndpointStateMachine.EndPointStates>

Enclosing class:

EndpointStateMachine

public static enum EndpointStateMachine.EndPointStates
extends Enum<EndpointStateMachine.EndPointStates>

States that an Endpoint can be in.

This is a sorted list of states that EndPoint will traverse.

getNextState() will move from FIRST to LAST.

Method Details

values

public static EndpointStateMachine.EndPointStates[] values()

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

Returns:

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

valueOf

public static EndpointStateMachine.EndPointStates 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

getNextState

public EndpointStateMachine.EndPointStates getNextState()

Returns the next logical state that endPoint should move to. The next state is computed by adding 1 to the current state.

Returns:

NextState.
