static int	STATUS_MARKED_ROLLBACK           A transaction is associated with the target object and it has been marked for rollback, perhaps as a result of a setRollbackOnly operation.
static int	STATUS_NO_TRANSACTION           No transaction is currently associated with the target object.
static int	STATUS_PREPARED           A transaction is associated with the target object and it has been prepared.
static int	STATUS_PREPARING           A transaction is associated with the target object and it is in the process of preparing.
static int	STATUS_ROLLEDBACK           A transaction is associated with the target object and the outcome has been determined to be rollback.
static int	STATUS_ROLLING_BACK           A transaction is associated with the target object and it is in the process of rolling back.

Field Detail

英文文档：

STATUS_ACTIVE

static final int STATUS_ACTIVE

A transaction is associated with the target object and it is in the active state. An implementation returns this status after a transaction has been started and prior to a Coordinator issuing any prepares, unless the transaction has been marked for rollback.

英文文档：

STATUS_MARKED_ROLLBACK

static final int STATUS_MARKED_ROLLBACK

A transaction is associated with the target object and it has been marked for rollback, perhaps as a result of a setRollbackOnly operation.

Constant Field Values

英文文档：

STATUS_PREPARED

static final int STATUS_PREPARED

A transaction is associated with the target object and it has been prepared. That is, all subordinates have agreed to commit. The target object may be waiting for instructions from a superior as to how to proceed.

Constant Field Values

英文文档：

STATUS_COMMITTED

static final int STATUS_COMMITTED

A transaction is associated with the target object and it has been committed. It is likely that heuristics exist; otherwise, the transaction would have been destroyed and NoTransaction returned.

英文文档：

STATUS_ROLLEDBACK

static final int STATUS_ROLLEDBACK

A transaction is associated with the target object and the outcome has been determined to be rollback. It is likely that heuristics exist; otherwise, the transaction would have been destroyed and NoTransaction returned.

Constant Field Values

英文文档：

STATUS_UNKNOWN

static final int STATUS_UNKNOWN

A transaction is associated with the target object but its current status cannot be determined. This is a transient condition and a subsequent invocation will ultimately return a different status.

Constant Field Values

英文文档：

STATUS_NO_TRANSACTION

static final int STATUS_NO_TRANSACTION

No transaction is currently associated with the target object. This will occur after a transaction has completed.

Constant Field Values

英文文档：

STATUS_PREPARING

static final int STATUS_PREPARING

A transaction is associated with the target object and it is in the process of preparing. An implementation returns this status if it has started preparing, but has not yet completed the process. The likely reason for this is that the implementation is probably waiting for responses to prepare from one or more Resources.

Constant Field Values

英文文档：

STATUS_COMMITTING

static final int STATUS_COMMITTING

A transaction is associated with the target object and it is in the process of committing. An implementation returns this status if it has decided to commit but has not yet completed the committing process. This occurs because the implementation is probably waiting for responses from one or more Resources.

Constant Field Values

英文文档：

STATUS_ROLLING_BACK

static final int STATUS_ROLLING_BACK

A transaction is associated with the target object and it is in the process of rolling back. An implementation returns this status if it has decided to rollback but has not yet completed the process. The implementation is probably waiting for responses from one or more Resources.
