All Implemented Interfaces:

java.lang.AutoCloseable, ByteBufferDestination

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.

Method Detail

writeHeader

private void writeHeader()

Writes the layout's header to the file if it exists.

isEndOfBatch

public java.lang.Boolean isEndOfBatch()

setEndOfBatch

public void setEndOfBatch(boolean endOfBatch)

write

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

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.

immediateFlush - flushes immediately after writing.

writeToDestination

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

Description copied from class: FileManager

Overrides OutputStreamManager.writeToDestination(byte[], int, int) to add support for file locking.

Overrides:

writeToDestination in class RollingFileManager

Parameters:

bytes - the array containing data

offset - from where to write

length - how many bytes to write

createFileAfterRollover

protected void createFileAfterRollover()
                                throws java.io.IOException

Overrides:

createFileAfterRollover in class RollingFileManager

Throws:

java.io.IOException

flush

public void flush()

Description copied from class: OutputStreamManager

Flushes any buffers.

Overrides:

flush in class OutputStreamManager

closeOutputStream

public boolean closeOutputStream()

Overrides:

closeOutputStream in class OutputStreamManager

getBufferSize

public int getBufferSize()

Returns the buffer capacity.

Overrides:

getBufferSize in class FileManager

Returns:

the buffer size

updateData

public void updateData(java.lang.Object data)

Overrides:

updateData in class RollingFileManager
