Note to self on how to approach this (draft):
FileManager
{code}
...
@Override
protected ByteBuffer createByteBuffer() {
return bufferSize > 0 ? ByteBuffer.wrap(new byte[bufferSize]) :
super.createByteBuffer();
}
...
// inner class
private static class FileManagerFactory implements ManagerFactory<FileManager,
FactoryData> {
...
public FileManager createManager(final String name, final FactoryData data) {
...
// if Constants.ENABLE_THREADLOCALS is true,
// we use ByteBufferDestination to buffer the data
if (data.bufferedIO && !Constants.ENABLE_THREADLOCALS) {
os = new BufferedOutputStream(os, bufferSize);
} else {
...
{code}
RollingFileManager
{code}
protected void createFileAfterRollover() throws IOException {
final OutputStream os = new FileOutputStream(getFileName(), isAppend());
// if Constants.ENABLE_THREADLOCALS is true,
// we use ByteBuffer to buffer the data.
// Negative buffer size means no buffering.
if (getBufferSize() > 0 && !Constants.ENABLE_THREADLOCALS) {
setOutputStream(new BufferedOutputStream(os, getBufferSize()));
} else {
setOutputStream(os);
