public LoggingConnectionDecorator()

Method Details

setPrettyPrint

public void setPrettyPrint(boolean prettyPrint)

If set to true, pretty-print SQL by running it through SQLFormatter.prettyPrint(java.lang.Object). If false, don't pretty-print, and output SQL logs in a single line. Pretty-printed SQL can be easier for a human to read, but is harder to parse with tools like grep.

getPrettyPrint

public boolean getPrettyPrint()

See Also:

• setPrettyPrint(boolean)

setPrettyPrintLineLength

public void setPrettyPrintLineLength(int length)

The number of characters to print per line when pretty-printing of SQL is enabled. Defaults to 60 to provide some space for any ant-related characters on the left of a standard 80-character display.

getPrettyPrintLineLength

public int getPrettyPrintLineLength()

See Also:

• setPrettyPrintLineLength(int)

getPrintParameters

public boolean getPrintParameters()

Whether parameter values will be printed in exception messages or in trace. This is different from trackParameters which controls whether OpenJPA will track parameters internally (visible while debugging and used in batching).

setPrintParameters

public void setPrintParameters(boolean printParameters)

setWarningAction

public void setWarningAction(String warningAction)

What to do with SQL warnings.

getWarningAction

public String getWarningAction()

What to do with SQL warnings.

setWarningHandler

public void setWarningHandler(LoggingConnectionDecorator.SQLWarningHandler warningHandler)

What to do with SQL warnings.

getWarningHandler

public LoggingConnectionDecorator.SQLWarningHandler getWarningHandler()

What to do with SQL warnings.

getLogs

public DataSourceLogs getLogs()

The log to write to.

                    throws SQLException
