Inherited Methods

Class: Log

Log::alert(): A convenience function for logging an alert event. It will log a message at the PEAR_LOG_ALERT log level.
Log::attach(): Adds a Log_observer instance to the list of observers that are listening for messages emitted by this Log instance.
Log::close(): Abstract implementation of the close() method.
Log::crit(): A convenience function for logging a critical event. It will log a message at the PEAR_LOG_CRIT log level.
Log::debug(): A convenience function for logging a debug event. It will log a message at the PEAR_LOG_DEBUG log level.
Log::detach(): Removes a Log_observer instance from the list of observers.
Log::emerg(): A convenience function for logging a emergency event. It will log a message at the PEAR_LOG_EMERG log level.
Log::err(): A convenience function for logging a error event. It will log a message at the PEAR_LOG_ERR log level.
Log::factory(): Attempts to return a concrete Log instance of type $handler.
Log::flush(): Abstract implementation of the flush() method.
Log::getIdent(): Returns the current identification string.
Log::getMask(): Returns the current level mask.
Log::getPriority(): Returns the current default priority.
Log::info(): A convenience function for logging a information event. It will log a message at the PEAR_LOG_INFO log level.
Log::isComposite(): Indicates whether this is a composite class.
Log::log(): Abstract implementation of the log() method.
Log::MASK(): Calculate the log mask for the given priority.
Log::MAX(): Calculate the log mask for all priorities less than or equal to the given priority. In other words, $priority will be the highests priority matched by the resulting mask.
Log::MIN(): Calculate the log mask for all priorities greater than or equal to the given priority. In other words, $priority will be the lowest priority matched by the resulting mask.
Log::notice(): A convenience function for logging a notice event. It will log a message at the PEAR_LOG_NOTICE log level.
Log::open(): Abstract implementation of the open() method.
Log::priorityToString(): Returns the string representation of a PEAR_LOG_* integer constant.
Log::setBacktraceDepth(): Sets the starting depth to use when walking a backtrace in search of the function that invoked the log system. This is used on conjunction with the 'file', 'line', 'function', and 'class' formatters.
Log::setIdent(): Sets this Log instance's identification string.
Log::setMask(): Set and return the level mask for the current Log instance.
Log::setPriority(): Sets the default priority to the specified value.
Log::singleton(): Attempts to return a reference to a concrete Log instance of type $handler, only creating a new instance if no log instance with the same parameters currently exists.
Log::stringToPriority(): Returns the the PEAR_LOG_* integer constant for the given string representation of a priority name. This function performs a case-insensitive search.
Log::UPTO(): Calculate the log mask for all priorities up to the given priority.
Log::warning(): A convenience function for logging a warning event. It will log a message at the PEAR_LOG_WARNING log level.
Log::_announce(): Informs each registered observer instance that a new message has been logged.
Log::_extractMessage(): Returns the string representation of the message data.
Log::_format(): Produces a formatted log line based on a format string and a set of variables representing the current log record and state.
Log::_isMasked(): Check if the given priority is included in the current level mask.

addChild [line 242]

boolean addChild(

&$child, object
$child)

close [line 78]

True close(
)

Closes all open child instances.

Return: if all of the opened child instances were successfully closed.
Access: public

Overrides Log::close() (Abstract implementation of the close() method.)

flush [line 109]

True flush(
)

isComposite [line 209]

boolean isComposite(
)

Returns true if this is a composite.

log [line 138]

boolean log(
mixed
$message, [string
$priority = null])

Sends $message and $priority to each child of this composite. If the appropriate children aren't already open, they will be opened here.

Return: True if the entry is successfully logged.
Access: public

Overrides Log::log() (Abstract implementation of the log() method.)

Parameters:

mixed	`$message`	—	String or object containing the message to log.
