void |
awaitReadable()
Block until this channel becomes readable again.
|
void |
awaitReadable(long time,
TimeUnit timeUnit)
Block until this conduit becomes readable again, or until the timeout expires.
|
int |
read(ByteBuffer dst)
Read a sequence of bytes from this conduit to the given buffer.
|
long |
read(ByteBuffer[] dsts,
int offs,
int len)
Read a sequence of bytes from this conduit to the given buffers.
|
void |
resumeReads()
Indicate that the conduit's
ReadReadyHandler should be invoked as soon as data can be read
without blocking. |
long |
transferTo(long count,
ByteBuffer throughBuffer,
StreamSinkChannel target)
Transfers bytes into the given channel target.
|
long |
transferTo(long position,
long count,
FileChannel target)
Transfers bytes into the given file from this channel.

throughBuffer
will be cleared. On exit, the buffer will be
flipped for emptying, and may possibly be empty or may contain data. If this method returns a value less than
count
, then the remaining data in throughBuffer
may contain data read from this channel which must
be written to target
to complete the operation.transferTo
