public RollingFileAppender()

Method Details

start

public void start()

Description copied from class: FileAppender

If the value of File is not null, then FileAppender.openFile(java.lang.String) is called with the values of File and Append properties.

Specified by:

start in interface LifeCycle

Overrides:

start in class FileAppender<E>

stop

public void stop()

Description copied from class: OutputStreamAppender

Stop this appender instance. The underlying stream or writer is also closed.

Stopped appenders cannot be reused.

Specified by:

stop in interface LifeCycle

Overrides:

stop in class FileAppender<E>

setFile

public void setFile(String file)

Description copied from class: FileAppender

The File property takes a string value which should be the name of the file to append to.

Overrides:

setFile in class FileAppender<E>

getFile

public String getFile()

Description copied from class: FileAppender

Returns the value of the File property.

This method may be overridden by derived classes.

Overrides:

getFile in class FileAppender<E>

rollover

public void rollover()

Implemented by delegating most of the rollover work to a rolling policy.

subAppend

protected void subAppend(E event)

This method differentiates RollingFileAppender from its super class.

Overrides:

subAppend in class OutputStreamAppender<E>

getRollingPolicy

public RollingPolicy getRollingPolicy()

getTriggeringPolicy

public TriggeringPolicy<E> getTriggeringPolicy()

setRollingPolicy

public void setRollingPolicy(RollingPolicy policy)

Sets the rolling policy. In case the 'policy' argument also implements TriggeringPolicy, then the triggering policy for this appender is automatically set to be the policy argument.

Parameters:

policy -

setTriggeringPolicy

public void setTriggeringPolicy(TriggeringPolicy<E> policy)

updateByteCount

protected void updateByteCount(byte[] byteArray)

Overrides:

updateByteCount in class OutputStreamAppender<E>
