public class LazyFileOutputStream
extends java.io.OutputStream

Class that delays opening the output file until the first bytes shall be written or the method `open` has been invoked explicitly.

Since:
  Ant 1.6

Constructor Summary
`LazyFileOutputStream(java.io.File f)` Creates a stream that will eventually write to the file with the given name and replace it.
`LazyFileOutputStream(java.io.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.
`LazyFileOutputStream(java.io.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).
`LazyFileOutputStream(java.lang.String name)` Creates a stream that will eventually write to the file with the given name and replace it.
`LazyFileOutputStream(java.lang.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.

Method Summary
`void` `close()`
`void` `open()` Explicitly open the file for writing.
`void` `write(byte[] b)` Delegates to the three arg version.
`void` `write(byte[] b, int offset, int len)`
`void` `write(int b)`
