protected TransactionStatistics(ExtendedStatisticsContainer container,
                     TimeService timeService)

Method Detail

isCommitted

public final boolean isCommitted()

Returns:

true if the transaction committed successfully, false otherwise

setOutcome

public final void setOutcome(boolean commit)

Sets the transaction outcome. See TransactionStatistics.isCommitted().

Parameters:

commit - true if the transaction is committed successfully.

isReadOnly

public final boolean isReadOnly()

Returns:

true if this transaction is a read-only transaction.

markAsUpdateTransaction

public final void markAsUpdateTransaction()

Sets this transaction as a write transaction. See also TransactionStatistics.isReadOnly().

addValue

public final void addValue(ExtendedStatistic stat,
            double value)

Adds a value to a statistic collected for this transaction.

getValue

public final double getValue(ExtendedStatistic stat)
                      throws ExtendedStatisticNotFoundException

Returns:

a value collected for this transaction.

Throws:

ExtendedStatisticNotFoundException - if the statistic collected was not found.

incrementValue

public final void incrementValue(ExtendedStatistic stat)

Increments a statistic value. It is equivalent to addValue(stat, 1).

terminateTransaction

public final void terminateTransaction()

Signals this transaction as completed and updates the statistics to the final values ready to be merged in the cache statistics.

flushTo

public final void flushTo(ConcurrentGlobalContainer globalContainer)

Merges this statistics in the global container.

toString

public String toString()

Overrides:

toString in class Object

onPrepareCommand

public abstract void onPrepareCommand()

Signals the reception of the PrepareCommand.

isLocalTransaction

public abstract boolean isLocalTransaction()

Returns:

true if this transaction statistics is for a local transaction.

terminate

protected abstract void terminate()

Signals this transaction as completed and updates the statistics to the final values ready to be merged in the cache statistics. This method is abstract in order to be override for the local and the remote transactions.

copyValue

protected final void copyValue(ExtendedStatistic from,
             ExtendedStatistic to)

Copies a statistic value and adds it to another statistic.
