Enum Constant Summary

Enum Constants

Enum Constant	Description
AGGRESSIVE_HARD_DELETE	In addition to queuing cells for "scrubbing", we also: - (a) Scrub earlier than we would have otherwise, even at the cost of possibly causing open transactions to abort, and - (b) Block until the scrub is complete.
DEFAULT
HARD_DELETE	Hard delete transactions are different from regular transactions because they must queue cells for "scrubbing" on every cell that's modified or deleted.

Method Summary

Modifier and Type	Method	Description
static Transaction.TransactionType	valueOf(String name)	Returns the enum constant of this type with the specified name.

Enum Constant Detail

DEFAULT

public static final Transaction.TransactionType DEFAULT

HARD_DELETE

public static final Transaction.TransactionType HARD_DELETE

Hard delete transactions are different from regular transactions because they must queue cells for "scrubbing" on every cell that's modified or deleted. (i.e. not just write a value at the latest timestamp, but also clean up values at older timestamps)

AGGRESSIVE_HARD_DELETE

public static final Transaction.TransactionType AGGRESSIVE_HARD_DELETE

In addition to queuing cells for "scrubbing", we also: - (a) Scrub earlier than we would have otherwise, even at the cost of possibly causing open transactions to abort, and - (b) Block until the scrub is complete.

Method Detail

values

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

Returns:

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

valueOf

public static Transaction.TransactionType 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
