Enum Constant Detail

NEW

public static final Session.Lifecycle NEW

A newly created Session is in this state. When a attach Operation is completed successfully -> ATTACHED. If Session.abort() is called -> ABORTING. No Operations other than attach and close will be performed. A Session in this state is 'open'.

ATTACHED

public static final Session.Lifecycle ATTACHED

fully operational. Work is queued and performed. If a close Operation is submitted -> CLOSING. If Session.abort() is called -> ABORTING. A Session in this state is 'open' and 'working'.

CLOSING

public static final Session.Lifecycle CLOSING

Work in progress is completed but no additional work can be submitted. Attempting to queue work throws IllegalStateException. When the close Operation is completed -> CLOSED. A Session in this state is 'closed' and 'working'.

ABORTING

public static final Session.Lifecycle ABORTING

Work is neither queued nor performed. The currently executing Operations, if any, are terminated immediately. Any queued Operations are removed from the queue. Attempting to queue work throws IllegalStateException. When the queue is empty -< CLOSED. A Session in this state is 'closed'.

CLOSED

public static final Session.Lifecycle CLOSED

Work is neither queued nor performed. Attempting to queue work throws IllegalStateException. A Session in this state is 'closed'.

Method Detail

values

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

Returns:

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

valueOf

public static Session.Lifecycle valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
