OptimizerTrace

public class OptimizerTrace (Code)

This class provides static methods for controlling the optimizer tracing in a Cloudscape database.

Cloudscape reserves the right to change, rename, or remove this interface at any time.

Method Summary
public static String	getOptimizerTraceOutput() Get the optimizer trace output for the last optimized query as a String.
public static boolean	setOptimizerTrace(boolean onOrOff) Control whether or not optimizer trace is on. Parameters: onOrOff - Whether to turn optimizer trace on (true) or off (false).
public static boolean	setOptimizerTraceHtml(boolean onOrOff) Control whether or not optimizer trace is generated in html. Parameters: onOrOff - Whether or not optimizer trace will be in html (true) or not (false).
public static boolean	writeOptimizerTraceOutputHtml(String fileName) Send the optimizer trace output for the last optimized query to a file with a .html extension.

Method Detail

getOptimizerTraceOutput
public static String getOptimizerTraceOutput()(Code)
	Get the optimizer trace output for the last optimized query as a String. If optimizer trace html is on, then the String will contain the html tags. The optimizer trace output for the last optimized query as a String.Null will be returned if optimizer trace output is off or not supported or no trace output was found or an exception occurred.

setOptimizerTrace
public static boolean setOptimizerTrace(boolean onOrOff)(Code)
	Control whether or not optimizer trace is on. Parameters: onOrOff - Whether to turn optimizer trace on (true) or off (false). Whether or not the call was successful. (false will be returned when optimizer tracing is not supported.)

setOptimizerTraceHtml
public static boolean setOptimizerTraceHtml(boolean onOrOff)(Code)
	Control whether or not optimizer trace is generated in html. Parameters: onOrOff - Whether or not optimizer trace will be in html (true) or not (false). Whether or not the call was successful. (false will be returned when optimizer tracing is not supported.)

writeOptimizerTraceOutputHtml
public static boolean writeOptimizerTraceOutputHtml(String fileName)(Code)
	Send the optimizer trace output for the last optimized query to a file with a .html extension. If optimizer trace html is on, then the output will contain the html tags. Parameters: fileName - The name of the file to write to. (.html extension will be added.) Whether or not the request was successful.false mayl be returned for a number of reasons, including if optimizer trace output is off or not supported or no trace output was found or an exception occurred.
