LazyFileOutputStream

• java.lang.Object
  • java.io.OutputStream

Fields Summary
private FileOutputStream	fos
private File	file
private boolean	append
private boolean	alwaysCreate
private boolean	opened
private boolean	closed

Constructors Summary
public LazyFileOutputStream(String name) Creates a stream that will eventually write to the file with the given name and replace it. param name the filename. this(name, false);
public LazyFileOutputStream(String name, boolean append) Creates a stream that will eventually write to the file with the given name and optionally append to instead of replacing it. param name the filename. param append if true append rather than replace. this(new File(name), append);
public LazyFileOutputStream(File f) Creates a stream that will eventually write to the file with the given name and replace it. param f the file to create. this(f, false);
public LazyFileOutputStream(File file, boolean append) Creates a stream that will eventually write to the file with the given name and optionally append to instead of replacing it. param file the file to create. param append if true append rather than replace. this(file, append, false);
public LazyFileOutputStream(File file, boolean append, boolean alwaysCreate) Creates a stream that will eventually write to the file with the given name, optionally append to instead of replacing it, and optionally always create a file (even if zero length). param file the file to create. param append if true append rather than replace. param alwaysCreate if true create the file even if nothing to write. this.file = file; this.append = append; this.alwaysCreate = alwaysCreate;

Methods Summary
public synchronized void	close() Close the file. throws IOException if there is an error. if (alwaysCreate && !closed) { ensureOpened(); } if (opened) { fos.close(); } closed = true;
private synchronized void	ensureOpened() if (closed) { throw new IOException(file + " has already been closed."); } if (!opened) { fos = new FileOutputStream(file.getAbsolutePath(), append); opened = true; }
public void	open() Explicitly open the file for writing. Returns silently if the file has already been opened. throws IOException if there is an error. ensureOpened();
public synchronized void	write(int b) Write a byte. param b the byte to write. throws IOException if there is a problem. ensureOpened(); fos.write(b);
public void	write(byte[] b) Delegates to the three-arg version. param b the bytearray to write. throws IOException if there is a problem. write(b, 0, b.length);
public synchronized void	write(byte[] b, int offset, int len) Write part of a byte array. param b the byte array. param offset write from this index. param len the number of bytes to write. throws IOException if there is a probem. ensureOpened(); fos.write(b, offset, len);
