Detailed Description

Tracks and logs the SQL that gets sent to the database. If the milliseconds used exceeds the time specified in the system property er.extensions.ERXSQLExpressionTracker.trace.milliSeconds.[debug|info|warn|error], and the entity name matches the regular expression er.extensions.ERXSQLExpressionTracker.trace.entityMatchPattern then the SQL expression is logged together with the time used and the parameters.
NOTE: To get patched into EOF, this class registers itself for the EODatabaseContext.DatabaseChannelNeededNotification notification and creates a new channel. If you would like to handle creation of the channel yourself *and* you need the logging feature, you need to:

• set the er.extensions.ERXAdaptorChannelDelegate.enabled=false in your properties, which will prevent creation of the channel here
• create the channel yourself and set the delegate to ERXAdaptorChannelDelegate()

otherwise you just need to set er.extensions.ERXAdaptorChannelDelegate.enabled=true

Member Function Documentation

void adaptorChannelDidEvaluateExpression	(	EOAdaptorChannel	channel,
		EOSQLExpression	expression
	)

void adaptorChannelDidFetchRow	(	EOAdaptorChannel	eoadaptorchannel,
		NSMutableDictionary	nsmutabledictionary
	)

Implemented so the the thread checks if it should get interrupted.

Parameters:

	eoadaptorchannel
	nsmutabledictionary

)

[private]

static void dataBaseChannelNeeded

(

NSNotification

n

)

[static]

Answers to the EODataBaseChannelNeeded notification. Creates a new EODatabaseChannel and sets its adaptorChannel delegate to a new instance of ERXAdaptorChannelDelegate.

Parameters:

n

synchronized void dumpLastStatements

(

)

Dump the last collected statements to the log. Use the property er.extensions.ERXSQLExpressionTracker.collectLastStatements set to true to collect executed statements.

LinkedList<String> lastStatements
