Summary

public class  CaptureOutputStream
     extends java.io.FilterOutputStream
{
          // Constructors 1
     public CaptureOutputStream(OutputStream, int);

          // Methods 3
     public byte[] getCaptured();
     public void write(byte[], int, int) throws IOException;
     public void write(int) throws IOException;
}

CaptureOutputStream is a FilterOutputStream that captures and retains the last N bytes written to it, where N is a constructor arg. A copy of the captured bytes can be returned at any time, even after close().

Bytes are NOT captured if the underlying OutputStream throws an IOException from its write().

Summary  |  Top

   public CaptureOutputStream(OutputStream out, 
                              int N) 

Writes to OutputStream, capturing last N bytes written.

   public byte[] getCaptured() 

Return a copy of the bytes most recently captured. This will be fewer than N in the constructor if less than N bytes have been written. This will be none (i.e. a zero-length byte[]) if no bytes have been written.

   public void write(int abyte)  throws IOException

Write one byte.

Overrides:

write in class FilterOutputStream

   public void write(byte[] bytes, 
                     int offset, 
                     int count)  throws IOException

Write range of byte-array.

Overrides:

write in class FilterOutputStream
