java.lang.Objectjava.io.OutputStream
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. | |
| Method Summary | |
|---|---|
|  void | close()Close the file. | 
|  void | open()Explicitly open the file for writing. | 
|  void | write(byte[] b)Delegates to the three-arg version. | 
|  void | write(byte[] b,
      int offset,

name - the filename.append - if true append rather than replace.public LazyFileOutputStream(java.io.File f)
f - the file to create.
public LazyFileOutputStream(java.io.File file,

public void open()
          throws java.io.IOException
Returns silently if the file has already been opened.
java.io.IOException - if there is an error.
public void close()
           throws java.io.IOException
close in interface java.io.Closeableclose in class java.io.OutputStreamjava.io.IOException - if there is an error.
public void write(byte[] b)
           throws java.io.IOException
write in class java.io.OutputStreamb - the bytearray to write.
java.io.IOException - if there is a problem.
public void write(byte[] b,
                  int offset,
                  int len)
           throws java.io.IOException
write in class java.io.OutputStreamb - the byte array.offset - write from this index.len - the number of bytes to write.
java.io.IOException - if there is a problem.
public void write(int b)
           throws java.io.IOException
write in class java.io.OutputStreamb - the byte to write.
