Enum Constant Detail

DONT_LOAD

public static final VisitableCommand.LoadType DONT_LOAD

Never load previous value.

PRIMARY

public static final VisitableCommand.LoadType PRIMARY

In non-transactional cache, load previous value only on the primary owner. In transactional cache, the value is fetched to originator. Primary then does not have to load the value but for write-skew check.

OWNER

public static final VisitableCommand.LoadType OWNER

In non-transactional cache, load previous value on both primary and backups. In transactional cache, the value is both fetched to originator and all owners have to load it because it is needed to produce the new value.

Method Detail

values

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

Returns:

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

valueOf

public static VisitableCommand.LoadType 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
