Constructor Detail

StreamTarget

public StreamTarget(OutputStream outputStream,
                    Formatter formatter,
                    String encoding)

Constructor that writes to a stream and uses a particular formatter.

Parameters:

outputStream - the OutputStream to write to

formatter - the Formatter to use

encoding - Desired encoding to use when writing to the log, null implies the default system encoding.

StreamTarget

public StreamTarget(OutputStream outputStream,
                    Formatter formatter)

Constructor that writes to a stream and uses a particular formatter.

Parameters:

outputStream - the OutputStream to write to

formatter - the Formatter to use

Method Detail

setOutputStream

protected void setOutputStream(OutputStream outputStream)

Set the output stream. Close down old stream and write tail if appropriate.

Parameters:

outputStream - the new OutputStream

write

protected void write(String data)

Abstract method that will output event.

Overrides:

write in class AbstractOutputTarget

Parameters:

data - the data to be output

close

public void close()

Shutdown target. Attempting to write to target after close() will cause errors to be logged.

Specified by:

close in interface Closeable

Overrides:

close in class AbstractOutputTarget

shutdownStream

protected void shutdownStream()

Shutdown output stream.
