org.apache.tools.ant.util.LazyFileOutputStream
public class LazyFileOutputStream
Class that delays opening the output file until the first bytes
shall be written or the method open has been invoked
explicitly.
| 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. |
