public java.lang.Object getAttribute(java.lang.String name)
null if there is no such attribute.
getAttribute in class LogFactoryname - Name of the attribute to returnpublic java.lang.String[] getAttributeNames()
getAttributeNames in class LogFactory
public Log getInstance(java.lang.Class clazz)
throws LogConfigurationException
getInstance(String) with it.
getInstance in class LogFactoryclazz - Class for which a suitable Log name will be derived
LogConfigurationException - if a suitable Log
instance cannot be returned
public Log getInstance(java.lang.String name)
throws LogConfigurationException
LogFactoryConstruct (if necessary) and return a Log instance,
using the factory's current set of configuration attributes.
NOTE - Depending upon the implementation of
the LogFactory you are using, the Log
instance you are returned may or may not be local to the current
application, and may or may not be returned again on a subsequent
call with the same name argument.
getInstance in class LogFactoryname - Logical name of the Log instance to be
returned (the meaning of this name is only known to the underlying
logging implementation that is being wrapped)
LogConfigurationException - if a suitable Log
instance cannot be returnedpublic void release()
Log
instances returned by this factory. This is useful in environments
like servlet containers, which implement application reloading by
throwing away a ClassLoader. Dangling references to objects in that
class loader would prevent garbage collection.
release in class LogFactorypublic void removeAttribute(java.lang.String name)
removeAttribute in class LogFactoryname - Name of the attribute to remove
public void setAttribute(java.lang.String name,
java.lang.Object value)
null value is equivalent to calling
removeAttribute(name).
setAttribute in class LogFactoryname - Name of the attribute to setvalue - Value of the attribute to set, or null
to remove any setting for this attribute
