Package org.apache.commons.logging.impl
Class AvalonLogger
java.lang.Object
org.apache.commons.logging.impl.AvalonLogger
- All Implemented Interfaces:
Log
Implementation of commons-logging Log interface that delegates all
logging calls to the Avalon logging abstraction: the Logger interface.
There are two ways in which this class can be used:
- the instance can be constructed with an Avalon logger
(by calling
AvalonLogger(Logger)
). In this case, it acts as a simple thin wrapping implementation over the logger. This is particularly useful when using a property setter. - the
setDefaultLogger(org.apache.avalon.framework.logger.Logger)
class property can be called which sets the ancestral Avalon logger for this class. AnyAvalonLogger
instances created through theLogFactory
mechanisms will output to child loggers of thisLogger
.
Note: AvalonLogger
does not implement Serializable
because the constructors available for it make this impossible to achieve in all
circumstances; there is no way to "reconnect" to an underlying Logger object on
deserialization if one was just passed in to the constructor of the original
object. This class was marked Serializable in the 1.0.4 release of
commons-logging, but this never actually worked (a NullPointerException would
be thrown as soon as the deserialized object was used), so removing this marker
is not considered to be an incompatible change.
