public class ConvertedAttachmentOutputStream
extends OutputStream

An output stream returned by an IConvertedPacketAttachment. Besides output stream regular features, this output stream allows the caller to write a complete or a part of an existing attachment. These additional write methods are more efficient than a byte-to-byte copy between two streams.

public ConvertedAttachmentOutputStream(com.ibm.rational.test.lt.testgen.core.internal.store.TemporaryAttachment attachment)
Method Detail

write

public void write(int b)
           throws IOException
Specified by:
write in class OutputStream
Throws:
IOException

write

public void write(byte[] b,
                  int off,
                  int len)
           throws IOException
Overrides:
write in class OutputStream
Throws:
IOException

write

public void write(byte[] b)
           throws IOException
Overrides:
write in class OutputStream
Throws:
IOException

write

public void write(IPacketAttachment attachment)
           throws IOException
Writes the content of an attachment to the receiver. The original content is referenced rather than copied, so this method is much more efficient than a loop reading bytes from the original attachment and writing them to the receiver.

Parameters:
attachment - A packet attachment.
Throws:
IOException - Any exception thrown by the I/O layer.

write

public void write(IPacketAttachment attachment,
                  InputStream inputStream)
           throws IOException
Writes the content of an input stream, starting at the stream current position, till the end of stream is reached.

Parameters:
attachment - If applicable, the attachment that the input stream was created from. If this argument is null, the stream will be copied. If this argument is non null, it must be the attachment that was used to create inputStream; in this case, the attachment content will be referenced rather than copied.
inputStream - An input stream. The remaining data in the input stream will be read and written to the receiver.
Throws:
IOException - Any exception thrown by the I/O layer.

close

public void close()
           throws IOException
Specified by:
close in interface Closeable
Overrides:
close in class OutputStream
Throws:
IOException
