All Implemented Interfaces:: Serializable, Comparable<SequenceState>

public enum SequenceState
extends Enum<SequenceState>
extends Enum<SequenceState>

The possible states of a sequence on both the RM source and RM destination.

Enum Constant Summary
`CLOSED` Sequence is closed.
`CLOSING` Sequence is in the process of being closed.
`CREATED` Sequence handshaking is complete.
`CREATING` Sequence creation handshaking is in progress.
`LAST_MESSAGE` Deprecated. RM 1.0 only
`LAST_MESSAGE_PENDING` Deprecated. RM 1.0 only
`NEW` Initial state of a sequence.
`TERMINATED` Sequence is terminated.
`TERMINATING` Sequence is in the process of being terminated.

`static boolean`	`isTerminalState(SequenceState state)`
`boolean`	`isValidTransition(SequenceState state)`
`static SequenceState`	`valueOf(String name)` Returns the enum constant of this type with the specified name.
`static SequenceState[]`	`values()` Returns an array containing the constants of this enum type, in the order they're declared.

Enum Constant Detail

NEW

public static final SequenceState NEW

Initial state of a sequence. Source: From construction till CreateSequence is sent Destination: Not used, transition directly to CREATING

CREATING

public static final SequenceState CREATING

Sequence creation handshaking is in progress. Source: From CreateSequence send till CreateSequenceResponse is fully processed. Destination: During processing of CreateSequence till CreateSequenceResponse is sent.

CREATED

public static final SequenceState CREATED

Sequence handshaking is complete. Processing sequence messages. Source: After processing CreateSequenceResponse until either a LastMessage is sent, sequence is closed, or sequence is terminated. Destination: After CreateSequenceResponse is sent till the sequence receives LastMessage, CloseSequence, TerminateSequence or the sequence times out. Timeout will cause the sequence to be forcibly terminated (in RM 1.1 and beyond this will send TerminateSequence to the RM source).

LAST_MESSAGE_PENDING

public static final SequenceState LAST_MESSAGE_PENDING

Deprecated. RM 1.0 only

RM 1.0 Only. Source: Indicates a LastMessage has been sent. Destination: Indicates a LastMessage has been received and is being processed.

LAST_MESSAGE

public static final SequenceState LAST_MESSAGE

Deprecated. RM 1.0 only

RM 1.0 Only. Source: Indicates a LastMessage has been sent and ack'd. Destination: Indicates a LastMessage has been received and ack'd.

CLOSING

public static final SequenceState CLOSING

Sequence is in the process of being closed. No sequence messages can be sent or received. Source: Upon send of CloseSequence until CloseSequenceResponse is processed. Destination: Upon receipt of CloseSequence until CloseSequenceResponse is sent.

CLOSED

public static final SequenceState CLOSED

Sequence is closed. No sequence messages can be sent or received. Source: After CloseSequenceResponse is processed. Destination: After CloseSequenceResponse is sent.

TERMINATING

public static final SequenceState TERMINATING

Sequence is in the process of being terminated. No sequence messages can be sent or received. Source: After sending TerminateSequence till TerminateSequenceResponse is processed. Destination: After TerminateSequence is received until TerminateSequenceResponse is sent. Timeout will cause the sequence to be forcibly terminated (in RM 1.1 and beyond this will send TerminateSequence to the RM source). Sequence moves immediately to TERMINATED.

TERMINATED

public static final SequenceState TERMINATED

Sequence is terminated. No sequence messages can be sent or received. Source: After TerminateSequenceResponse is processed. Destination: After TerminateSequenceResponse is sent. Timeout will cause the sequence to be forcibly terminated (in RM 1.1 and beyond this will send TerminateSequence to the RM source). Sequence moves immediately to TERMINATED.

Method Detail

values

public static SequenceState[] values()

Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:

for(SequenceState c : SequenceState.values())
        System.out.println(c);

Returns:: an array containing the constants of this enum type, in the order they're declared

valueOf

public static SequenceState 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

isValidTransition

public boolean isValidTransition(SequenceState state)

isTerminalState

public static boolean isTerminalState(SequenceState state)

isClosedState

public static boolean isClosedState(SequenceState state)
