Constructor Detail

ResponseStream

public ResponseStream(java.io.OutputStream outputStream)

Core of the response stream. This class basically needs a new output stream to capture the artifact to.

Parameters:

outputStream - New output stream that is to be used to capture the response.

Method Detail

close

public void close()
           throws java.io.IOException

Closes the output stream

Specified by:

close in interface java.io.Closeable

Overrides:

close in class java.io.OutputStream

Throws:

java.io.IOException

flush

public void flush()
           throws java.io.IOException

Flushes the output stream

Specified by:

flush in interface java.io.Flushable

Overrides:

flush in class java.io.OutputStream

Throws:

java.io.IOException

write

public void write(int b)
           throws java.io.IOException

Standard write method that is used by downstream response processing.

Specified by:

write in class java.io.OutputStream

Parameters:

b - Byte of data to be written to the new captured output stream.

Throws:

java.io.IOException

write

public void write(byte[] b)
           throws java.io.IOException

Standard write method that is used by downstream response processing.

Overrides:

write in class java.io.OutputStream

Parameters:

b - Array of bytes to be written to the new captured output stream.

Throws:

java.io.IOException

write

public void write(byte[] b,
                  int off,
                  int len)
           throws java.io.IOException

Standard write method that is used by downstream response processing.

Overrides:

write in class java.io.OutputStream

Parameters:

b - Array of bytes to be written to the new captured output stream.

off - Offset of where to write the bytes to the new captured output stream.

len - Number of bytes to the new captured output stream.

Throws:

java.io.IOException
