public static final RemoteInputStream.Flag GREEDY
RemoteInputStreamand send data to the other side.
RemoteInputStreamis normally unbuffered, in the sense that it will never attempt to read ahead and only read bytes that are explicitly requested via
InputStream.read(byte, int, int)methods (and other overloads.)
This is sometimes important, for example if you are going to pass InputStream to the other side, read specific amount of bytes from the other side, then come back to this side and keep reading.
But inability to read ahead means every
RemoteInputStream.read(byte, int, int) call incurs
a remote roundtrip. A local buffering via
BufferedInputStream would help,
but you'd still block on a roundtrip whenever a buffer goes empty.
When this flag is set, it changes the underlying data transfer model of
RemoteInputStream from pull to push. The side that created
will launch a thread and start proactively sending data to the other side.
The side that received
RemoteInputStream will buffer this content,
and so now
RemoteInputStream.read(byte, int, int) will only block
when there's no data. In this way, it hides the network latency completely
when you send a large amount of data.
When communicating with earlier version of the remoting library on the other side, the channel falls back and behaves as if this flag was not specified.
