Enum RoleRecvStatus

java.lang.Object

java.lang.Enum<RoleRecvStatus>

org.onosproject.openflow.controller.driver.RoleRecvStatus

All Implemented Interfaces:

Serializable, Comparable<RoleRecvStatus>

public enum RoleRecvStatus
extends Enum<RoleRecvStatus>

When we remove a pending role request we use this enum to indicate how we arrived at the decision. When we send a role request to the switch, we also use this enum to indicate what we expect back from the switch, so the role changer can match the reply to our expectation.

Enum Constant Summary

Enum Constants

Enum Constant and Description
MATCHED_CURRENT_ROLE The reply's role matched the role that this controller set in the request message - invoked either initially at startup or to reassert current role.
MATCHED_SET_ROLE The reply's role matched the role that this controller set in the request message - this is the result of a callback from the global registry, followed by a role request sent to the switch.
NO_REPLY The request timed out.
OLD_REPLY The reply was old, there is a newer request pending.
OTHER_EXPECTATION We received a role reply message from the switch but the expectation was unclear, or there was no expectation.
REPLY_QUERY The reply's role was a response to the query made by this controller.
UNSUPPORTED The switch returned an error indicating that roles are not.

Method Detail

values

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

Returns:

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

valueOf

public static RoleRecvStatus 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
