Method Detail

values

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

Returns:

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

valueOf

public static DNSState 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

toString

public final String toString()

Overrides:

toString in class Enum<DNSState>

advance

public final DNSState advance()

Returns the next advanced state.
In general, this advances one step in the following sequence: PROBING_1, PROBING_2, PROBING_3, ANNOUNCING_1, ANNOUNCING_2, ANNOUNCED.
or CANCELING_1, CANCELING_2, CANCELING_3, CANCELED Does not advance for ANNOUNCED and CANCELED state.

Returns:

next state

revert

public final DNSState revert()

Returns to the next reverted state. All states except CANCELED revert to PROBING_1. Status CANCELED does not revert.

Returns:

reverted state

isProbing

public final boolean isProbing()

Returns true, if this is a probing state.

Returns:

true if probing state, false otherwise

isAnnouncing

public final boolean isAnnouncing()

Returns true, if this is an announcing state.

Returns:

true if announcing state, false otherwise

isAnnounced

public final boolean isAnnounced()

Returns true, if this is an announced state.

Returns:

true if announced state, false otherwise

isCanceling

public final boolean isCanceling()

Returns true, if this is a canceling state.

Returns:

true if canceling state, false otherwise

isCanceled

public final boolean isCanceled()

Returns true, if this is a canceled state.

Returns:

true if canceled state, false otherwise

isClosing

public final boolean isClosing()

Returns true, if this is a closing state.

Returns:

true if closing state, false otherwise

isClosed

public final boolean isClosed()

Returns true, if this is a closing state.

Returns:

true if closed state, false otherwise
