Cloneable, InputBuffer

public class StreamInputBuffer

extends InputBufferImpl

For use in testing only; not efficient at all, and not completely implemented either. See ostore.mac.HMACDHHandler for an example use.

Constructor Summary

StreamInputBuffer(InputStream stream)

Method Summary

byte	nextByte() Read the next byte out of the buffer.
void	nextBytes(byte[] data, int offset, int length) Read the next length bytes out the of the buffer, and place them in the array output, starting at index offset.

StreamInputBuffer

public StreamInputBuffer(InputStream stream)

Method Detail

nextByte

public byte nextByte()

Description copied from interface: InputBuffer

Read the next byte out of the buffer.

nextBytes

public void nextBytes(byte[] data,
                      int offset,
                      int length)

Description copied from interface: InputBuffer

Read the next length bytes out the of the buffer, and place them in the array output, starting at index offset.

Parameters:

data - the array into which the bytes are written

offset - the index in output at which we start writing bytes

length - the number of bytes to read

nextBytes

public void nextBytes(OutputBuffer outb)

Description copied from interface: InputBuffer

Write all of the remaining bytes in this input buffer into the given output buffer. We need something like this so that (for example) the payload of an RouteMsg doesn't have to be deserialized on an intermediate node in its path. I'm not entirely happy with the idea, though, so please don't use it for now without talking to me first about what you're using it for.

Parameters:

outb - the output buffer into which the bytes are written

subBuffer

public InputBuffer subBuffer(int length)

Description copied from interface: InputBuffer

Create a new input buffer from the read point at this one, containing the next length bytes. Subject to change in the future.
