public class RollingRandomAccessFileManager
extends RollingFileManager

Extends RollingFileManager but instead of using a buffered output stream, this class uses a ByteBuffer and a RandomAccessFile to do the I/O.

isEndOfBatch

public Boolean isEndOfBatch()

setEndOfBatch

public void setEndOfBatch(boolean isEndOfBatch)

write

protected void write(byte[] bytes,
                     int offset,
                     int length)

Description copied from class: OutputStreamManager

Some output streams synchronize writes while others do not. Synchronizing here insures that log events won't be intertwined.

Overrides:

write in class RollingFileManager

Parameters:

bytes - The serialized Log event.

offset - The offset into the byte array.

length - The number of bytes to write.

createFileAfterRollover

protected void createFileAfterRollover()
                                throws IOException

Overrides:

createFileAfterRollover in class RollingFileManager

Throws:

IOException

flush

public void flush()

Description copied from class: OutputStreamManager

Flushes any buffers.

Overrides:

flush in class OutputStreamManager

close

public void close()

Overrides:

close in class OutputStreamManager

getBufferSize

public int getBufferSize()

Returns the buffer capacity.

Overrides:

getBufferSize in class FileManager

Returns:

the buffer size
