Enum Constant Detail

NONE

public static final RuntimeContext.TransactionState NONE

No transaction exists.

IN_PROGRESS

public static final RuntimeContext.TransactionState IN_PROGRESS

Started, still in progress.

May flush, commit or abort.

MUST_ABORT

public static final RuntimeContext.TransactionState MUST_ABORT

Started, but has hit an exception.

May not IsisTransaction#flush() or commit (will throw an IllegalStateException), but can only abort.

Similar to setRollbackOnly in EJBs.

COMMITTED

public static final RuntimeContext.TransactionState COMMITTED

Completed, having successfully committed.

May not IsisTransaction#flush() or abort or commit (will throw IllegalStateException).

ABORTED

public static final RuntimeContext.TransactionState ABORTED

Completed, having aborted.

May not IsisTransaction#flush(), commit or abort (will throw IllegalStateException).

Method Detail

values

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

Returns:

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

valueOf

public static RuntimeContext.TransactionState 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

public boolean canFlush()

Whether it is valid to flush this transaction.

canCommit

public boolean canCommit()

canAbort

public boolean canAbort()

Whether it is valid to abort this transaction.

isComplete

public boolean isComplete()

Whether the transaction is complete (and so a new one can be started).

mustAbort
