Method Detail

doPublish

protected void doPublish(ExtLogRecord record)

Do the actual work of publication; the record will have been filtered already. The default implementation does nothing except to flush if the autoFlush property is set to true; if this behavior is to be preserved in a subclass then this method should be called after the record is physically written.

Overrides:

doPublish in class ExtHandler

Parameters:

record - the log record to publish

preWrite

protected void preWrite(ExtLogRecord record)

Execute any pre-write policy, such as file rotation. The write lock is held during this method, so make it quick. The default implementation does nothing.

Parameters:

record - the record about to be logged

setWriter

public void setWriter(Writer writer)

Set the writer. The writer will then belong to this handler; when the handler is closed or a new writer is set, this writer will be closed.

Parameters:

writer - the new writer, or null to disable logging

flush

public void flush()

Flush this logger.

Specified by:

flush in interface Flushable

Overrides:

flush in class ExtHandler

close

public void close()
           throws SecurityException

Close this logger.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close in class ExtHandler

Throws:

SecurityException - if the caller does not have sufficient permission

safeClose

protected void safeClose(Closeable c)

Safely close the resource, reporting an error if the close fails.

Parameters:

c - the resource
