      com.threerings.export.util.LazyFileOutputStream

All Implemented Interfaces:

Closeable, Flushable

public class LazyFileOutputStream
extends OutputStream

Creates a FileOutputStream lazily, when data is actually written to the stream. For XML exports, this allows us to avoid overwriting any existing file when an exception is thrown in the process of building the object model before writing it out to the stream.

Field Summary

protected File	_file The file to which we will write.
protected FileOutputStream	_out The underlying file output stream, if created.

Constructor Summary

LazyFileOutputStream(File file)
Creates a new lazy stream to write to the specified file.

LazyFileOutputStream(String file)
Creates a new lazy stream to write to the named file.

Method Summary

void	close()
protected void	ensureInitialized() Creates the underlying output stream if necessary.
void	flush()
void	write(byte[] b)
void	write(byte[] b, int off, int len)
void	write(int b)
