Enum Constant Detail

THROW_EXCEPTION

public static final TransactionReadSentinelBehavior THROW_EXCEPTION

Throw an exception when a sentinel is read. This is the default value.

IGNORE

public static final TransactionReadSentinelBehavior IGNORE

Ignore the sentinel read, and pretend that there is no value for this cell. This should only be used internally for special long running transactions.

Method Detail

values

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

Returns:

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

valueOf

public static TransactionReadSentinelBehavior 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
