Method Detail

getBundle

Bundle getBundle()
Returns the bundle that created this LogEntry object.

Returns:
The bundle that created this LogEntry object; null if no bundle is associated with this LogEntry object.

getServiceReference

ServiceReference getServiceReference()
Returns the ServiceReference object for the service associated with this LogEntry object.

Returns:
ServiceReference object for the service associated with this LogEntry object; null if no ServiceReference object was provided.

getLevel

int getLevel()
Returns the severity level of this LogEntry object.

This is one of the severity levels defined by the LogService interface.

Returns:
Severity level of this LogEntry object.
See Also:
LogService.LOG_ERROR, LogService.LOG_WARNING, LogService.LOG_INFO, LogService.LOG_DEBUG

getMessage

java.lang.String getMessage()
Returns the human readable message associated with this LogEntry object.

Returns:
String containing the message associated with this LogEntry object.

getException

java.lang.Throwable getException()
Returns the exception object associated with this LogEntry object.

In some implementations, the returned exception may not be the original exception. To avoid references to a bundle defined exception class, thus preventing an uninstalled bundle from being garbage collected, the Log Service may return an exception object of an implementation defined Throwable subclass. The returned object will attempt to provide as much information as possible from the original exception object such as the message and stack trace.

Returns:
Throwable object of the exception associated with this LogEntry; null if no exception is associated with this LogEntry objcet.

getTime

long getTime()
Returns the value of currentTimeMillis() at the time this LogEntry object was created.

Returns:
The system time in milliseconds when this LogEntry object was created.

"System.currentTimeMillis()"
