public class RateLimitingStreamSinkConduit extends AbstractStreamSinkConduit<StreamSinkConduit>
Allows send speed to be throttled
Note that throttling is applied after an initial write, so if a big write is performed initially it may be a while before it can write again.

Modifier and Type | Method and Description |
---|---|
void |
awaitWritable()
Block until this channel becomes writable again.
|
void |
awaitWritable(long time,
TimeUnit timeUnit)
Block until this conduit becomes writable again, or until the timeout expires.
|
boolean |
isWriteResumed()
Determine whether write notifications are currently enabled.
|
void |
resumeWrites()
Indicate that the conduit's
WriteReadyHandler should be invoked as soon as data can be written
without blocking. |
void |
suspendWrites()
Indicate that calling the conduit's
WriteReadyHandler should be suspended. |
long |
transferFrom(FileChannel src,
long position,
long count)
Transfer bytes into this conduit from the given file.
|
long |
transferFrom(StreamSourceChannel source,
long count,
ByteBuffer throughBuffer)
Transfers bytes from the given channel source.
|
void |
wakeupWrites()
Indicate that the conduit's
WriteReadyHandler should be invoked immediately, and then again as soon
as data can be written without blocking. |
int |
write(ByteBuffer src)
Writes a sequence of bytes to this conduit from the given buffer.
|
long |
write(ByteBuffer[] srcs,
int offs,
int len)
Writes a sequence of bytes to this conduit from the given buffers.
|
int |
writeFinal(ByteBuffer src)
Writes some data to the conduit, with the same semantics as
StreamSinkConduit.write(java.nio.ByteBuffer) . |
long |
writeFinal(ByteBuffer[] srcs,
int offs,
int len)
Writes some data to the conduit, with the same semantics as
StreamSinkConduit.write(java.nio.ByteBuffer[], int, int) . |
