The interface for channels that can read data into a set of buffers in a
single operation. The corresponding interface for writes is
GatheringByteChannel.

Reads bytes from this channel and stores them in a subset of the
specified array of buffers. The subset is defined by offset and
length, indicating the first buffer and the number of buffers to
use. This method attempts to read as many bytes as can be stored in the
buffer subset from the channel and returns the number of bytes actually
read.
If a read operation is in progress, subsequent threads will block until the read is completed and will then contend for the ability to read.
| buffers | the array of byte buffers into which the bytes will be copied. |
|---|---|
| offset | the index of the first buffer to store bytes in. |
| length | the maximum number of buffers to store bytes in. |
| AsynchronousCloseException | if the channel is closed by another thread during this read operation. |
|---|---|
| ClosedByInterruptException | if another thread interrupts the calling thread while the operation is in progress. The interrupt state of the calling thread is set and the channel is closed. |
| ClosedChannelException | if the channel is closed. |
| IndexOutOfBoundsException | if offset < 0 or length < 0, or if
offset + length is greater than the size of
buffers. |
| IOException | if another I/O error occurs; details are in the message. |
| NonWritableChannelException | if the channel has not been opened in a mode that permits reading. |
Reads bytes from this channel into the specified array of buffers.
This method is equivalent to read(buffers, 0, buffers.length);
| buffers | the array of byte buffers to store the bytes being read. |

| AsynchronousCloseException | if the channel is closed by another thread during this read operation. |

| ClosedByInterruptException | if another thread interrupts the calling thread while the operation is in progress. The interrupt state of the calling thread is set and the channel is closed. |
| ClosedChannelException | if the channel is closed. |
| IOException | if another I/O error occurs; details are in the message. |
| NonWritableChannelException | if the channel has not been opened in a mode that permits reading. |
