Constructor Details

ProcessAwareServerOutputStream

public ProcessAwareServerOutputStream(ServerOutputStream unsafeOutputStream,
 ManagedObjectContext context)

Instantiate.

Parameters:

unsafeOutputStream - Unsafe ServerOutputStream.

context - ManagedObjectContext.

Method Details

write

public void write(ByteBuffer buffer)
           throws IOException

Description copied from class: ServerOutputStream

Writes a ByteBuffer.

This is to enable efficient I/O of writing content (typically cached).

Specified by:

write in class ServerOutputStream

Parameters:

buffer - ByteBuffer that should never change its content.

Throws:

IOException - If fails to write the ByteBuffer.

write

public void write(FileChannel file,
 long position,
 long count,
 FileCompleteCallback callback)
           throws IOException

Description copied from class: ServerOutputStream

Writes part of the FileChannel contents.

This is to enable efficient I/O (ie DMA) of writing FileChannel content.

To write the entire FileChannel contents, invoke write(file, 0, -1).

Note that the underlying implementation will need to support FileChannel efficiencies.

Specified by:

write in class ServerOutputStream

Parameters:

file - FileChannel.

position - Position within the FileChannel to start writing content. Must be non-negative number.

count - Count of bytes to write from the FileChannel. A negative value (typically -1) indicates to write the remaining FileChannel content from position.

callback - Optional FileCompleteCallback. May be null.

Throws:

IOException - If fails to write the FileChannel content.

write

public void write(FileChannel file,
 FileCompleteCallback callback)
           throws IOException

Description copied from class: ServerOutputStream

Writes the entire FileChannel contents.

This is a convenience method for write(file, 0, -1).

Specified by:

write in class ServerOutputStream

Parameters:

file - FileChannel.

callback - Optional FileCompleteCallback. May be null.

Throws:

IOException - If fails to write the FileChannel content.

write

Specified by:

write in class OutputStream

Throws:

IOException

flush

public void flush()
           throws IOException

Specified by:

flush in interface Flushable

Overrides:

flush in class OutputStream

Throws:

IOException

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class OutputStream

Throws:

IOException
