Enum Constant Detail

VENDORSPECIFIC

public static final ConcurrencyMode VENDORSPECIFIC

The concurrency control is decided by the SIP servlet container. The container is expected to keep the backward compatibility with SIP servlet 1.1 specification if an application specifies this as the concurrency mode.

APPLICATIONSESSION

public static final ConcurrencyMode APPLICATIONSESSION

Indicate that the container performs concurrency control at the level of application session. It make sure that two messages belonging to the same application session are never processed simultaneously. It also make sure various timer tasks or internal threads managed by the container that access the application session are not executed at the same time.

Method Detail

values

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

Returns:

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

valueOf

public static ConcurrencyMode 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
