LogRecord

public LogRecord()

getLevel

public LogLevel getLevel()

Get the level of this LogRecord.

Returns:

The LogLevel of this record.

See Also:

setLevel(LogLevel), LogLevel

setLevel

public void setLevel(LogLevel level)

Set the level of this LogRecord.

Parameters:

level - The LogLevel for this record.

See Also:

getLevel(), LogLevel

isSevereLevel

public abstract boolean isSevereLevel()

Abstract method. Must be overridden to indicate what log level to show in red.

hasThrown

public boolean hasThrown()

Returns:

true if getThrown().toString() is a non-empty string.

isFatal

public boolean isFatal()

Returns:

true if isSevereLevel() or hasThrown() returns true.

getCategory

public String getCategory()

Get the category asscociated with this LogRecord. For a more detailed description of what a category is see setCategory().

Returns:

The category of this record.

See Also:

setCategory(String)

setCategory

public void setCategory(String category)

Set the category associated with this LogRecord. A category represents a hierarchical dot (".") separated namespace for messages. The definition of a category is application specific, but a common convention is as follows:

When logging messages for a particluar class you can use its class name: com.thoughtworks.framework.servlet.ServletServiceBroker.

Futhermore, to log a message for a particular method in a class add the method name: com.thoughtworks.framework.servlet.ServletServiceBroker.init().

Parameters:

category - The category for this record.

See Also:

getCategory()

getMessage

public String getMessage()

Get the message asscociated with this LogRecord.

Returns:

The message of this record.

See Also:

setMessage(String)

setMessage

public void setMessage(String message)

Set the message associated with this LogRecord.

Parameters:

message - The message for this record.

See Also:

getMessage()

getSequenceNumber

public long getSequenceNumber()

Get the sequence number associated with this LogRecord. Sequence numbers are generally assigned when a LogRecord is constructed. Sequence numbers start at 0 and increase with each newly constructed LogRocord.

Returns:

The sequence number of this record.

See Also:

setSequenceNumber(long)

setSequenceNumber

public void setSequenceNumber(long number)

Set the sequence number assocsiated with this LogRecord. A sequence number will automatically be assigned to evey newly constructed LogRecord, however, this method can override the value.

Parameters:

number - The sequence number.

See Also:

getSequenceNumber()

getMillis

public long getMillis()

Get the event time of this record in milliseconds from 1970. When a LogRecord is constructed the event time is set but may be overridden by calling setMillis();

Returns:

The event time of this record in milliseconds from 1970.

See Also:

setMillis(long)

setMillis

public void setMillis(long millis)

Set the event time of this record. When a LogRecord is constructed the event time is set but may be overridden by calling this method.

Parameters:

millis - The time in milliseconds from 1970.

See Also:

getMillis()

getThreadDescription

public String getThreadDescription()

Get the thread description asscociated with this LogRecord. When a LogRecord is constructed, the thread description is set by calling: Thread.currentThread().toString(). You may supply a thread description of your own by calling the setThreadDescription(String) method.

Returns:

The thread description of this record.

See Also:

setThreadDescription(String)

setThreadDescription

public void setThreadDescription(String threadDescription)

Set the thread description associated with this LogRecord. When a LogRecord is constructed, the thread description is set by calling: Thread.currentThread().toString(). You may supply a thread description of your own by calling this method.

Parameters:

threadDescription - The description of the thread for this record.

See Also:

getThreadDescription()

getThrownStackTrace

public String getThrownStackTrace()

Get the stack trace in a String-based format for the associated Throwable of this LogRecord. The stack trace in a String-based format is set when the setThrown(Throwable) method is called.

Why do we need this method considering that we have the getThrown() and setThrown() methods? A Throwable object may not be serializable, however, a String representation of it is. Users of LogRecords should generally call this method over getThrown() for the reasons of serialization.

Returns:

The Stack Trace for the asscoiated Throwable of this LogRecord.

See Also:

setThrown(Throwable), getThrown()

setThrownStackTrace

public void setThrownStackTrace(String trace)

Set the ThrownStackTrace for the log record.

Parameters:

trace - A String to associate with this LogRecord

See Also:

getThrownStackTrace()

getThrown

public Throwable getThrown()

Get the Throwable associated with this LogRecord.

Returns:

The LogLevel of this record.

See Also:

setThrown(Throwable), getThrownStackTrace()

setThrown

public void setThrown(Throwable thrown)

Set the Throwable associated with this LogRecord. When this method is called, the stack trace in a String-based format is made available via the getThrownStackTrace() method.

Parameters:

thrown - A Throwable to associate with this LogRecord.

See Also:

getThrown(), getThrownStackTrace()

toString

public String toString()

Return a String representation of this LogRecord.

getNDC

public String getNDC()

Get the NDC (nested diagnostic context) for this record.

Returns:

The string representing the NDC.

setNDC

public void setNDC(String ndc)

Set the NDC (nested diagnostic context) for this record.

Parameters:

ndc - A string representing the NDC.

getLocation

public String getLocation()

Get the location in code where this LogRecord originated.

Returns:

The string containing the location information.

setLocation

public void setLocation(String location)

Set the location in code where this LogRecord originated.

resetSequenceNumber

public static void resetSequenceNumber()

Resets that sequence number to 0.

getNextId

protected static long getNextId()
