Modifier and Type	Method and Description
void	addStackTrace(long threadId, boolean runnable, ThreadType type, java.lang.StackTraceElement... stackTrace)
void	beforeSampling()
void	dispatcherTransactionCancelled(Transaction transaction) The transaction on the current thread is being cancelled, either because of a serious internal error or because the activity on the current thread is now linked to another transaction and this transaction should not report.
void	dispatcherTransactionFinished(TransactionData td, TransactionStats stats) This usually runs on the request thread, but for transactions that end because of a token timing out, it can be called from an arbitrary thread that happens to run the onRemoval listener in TimedTokenSet.
void	dispatcherTransactionStarted(Transaction transaction) Called after a dispatcher transaction is started on the request thread.

dispatcherTransactionStarted

public void dispatcherTransactionStarted(Transaction transaction)

Description copied from interface: ExtendedTransactionListener

Called after a dispatcher transaction is started on the request thread.

Specified by:

dispatcherTransactionStarted in interface ExtendedTransactionListener

Parameters:

transaction - The transaction that was just started

dispatcherTransactionFinished

public void dispatcherTransactionFinished(TransactionData td,

Parameters:

td - the final data from the transaction

stats - the final metric information from the transaction

dispatcherTransactionCancelled

public void dispatcherTransactionCancelled(Transaction transaction)

Description copied from interface: ExtendedTransactionListener

The transaction on the current thread is being cancelled, either because of a serious internal error or because the activity on the current thread is now linked to another transaction and this transaction should not report.

Specified by:

dispatcherTransactionCancelled in interface ExtendedTransactionListener

Parameters:

transaction - the transaction that is completing abruptly.
