Class OutputContext

java.lang.Object

com.couchbase.mock.memcached.OutputContext

public class OutputContext
extends Object

This class is used for fine-grained output manipulation. It implements a system of smaller chunks into which responses are buffered. This is used by the MemcachedServer class to simulate network slowness.

Constructor Detail

OutputContext

public OutputContext(List<ByteBuffer> origBufs)

Create a new OuputContext

Parameters:

origBufs - A list of buffers which should be set as the initial buffers. If empty, additional buffers will be created as needed

Method Detail

getIov

public ByteBuffer[] getIov()

Get an array of buffers representing all the active chunks

Returns:

An array of buffers

hasRemaining

public boolean hasRemaining()

Check if there are unsent chunks

Returns:

true if not empty

getSlice

public OutputContext getSlice(int limit)

Get an OutputBuffer containing a subset of the current one

Parameters:

limit - How many bytes should be available

Returns:

a new OutputContext

updateBytesSent

public void updateBytesSent(long num)

Indicate that some data has been flushed to the network

Parameters:

num - ignored for now. This is because each individual ByteBuffer keeps track of how many of its bytes were sent

releaseRemaining

public List<ByteBuffer> releaseRemaining()

Truncate the output. This will empty the list of chunks

Returns:

The list of remaining chunks.

toString

public String toString()

Overrides:

toString in class Object
