Modifier and Type | Method and Description |
---|---|
boolean |
isReadResumed()
Determine whether read notifications are currently enabled.
|
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. |
void |
suspendReads()
Indicate that calling the conduit's
ReadReadyHandler should be suspended. |
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.
|
void |
wakeupReads()
Indicate that the conduit's
ReadReadyHandler should be invoked immediately, and then again as soon
as data can be read without blocking. |
