Method Detail

getContainer

public org.apache.catalina.Container getContainer()
Return the Container with which this Logger has been associated.

Specified by:
getContainer in interface org.apache.catalina.Logger

setContainer

public void setContainer(org.apache.catalina.Container container)
Set the Container with which this Logger has been associated.

Specified by:
setContainer in interface org.apache.catalina.Logger
Parameters:
container - The associated Container

getInfo

public java.lang.String getInfo()
Return descriptive information about this Logger implementation and the corresponding version number, in the format <description>/<version>.

Specified by:
getInfo in interface org.apache.catalina.Logger

getVerbosity

public int getVerbosity()
Return the verbosity level of this logger. Messages logged with a higher verbosity than this level will be silently ignored.

Specified by:
getVerbosity in interface org.apache.catalina.Logger

setVerbosity

public void setVerbosity(int verbosity)
Set the verbosity level of this logger. Messages logged with a higher verbosity than this level will be silently ignored.

Specified by:
setVerbosity in interface org.apache.catalina.Logger
Parameters:
verbosity - The new verbosity level

setVerbosityLevel

public void setVerbosityLevel(java.lang.String verbosity)
Set the verbosity level of this logger. Messages logged with a higher verbosity than this level will be silently ignored.

Parameters:
verbosity - The new verbosity level, as a string

setHomeDir

public void setHomeDir(java.lang.String homeDir)
Required parameter so we can find the Log4J config file.


addPropertyChangeListener

public void addPropertyChangeListener(java.beans.PropertyChangeListener listener)
Add a property change listener to this component.

Specified by:
addPropertyChangeListener in interface org.apache.catalina.Logger
Parameters:
listener - The listener to add

log

public void log(java.lang.Exception exception,
                java.lang.String msg)

log

public void log(java.lang.String message,
